Awesome! By the way, the ACR-1 dash control knob is the correct one for the LC2i, in case you're curious. Thanks for supporting AudioControl and enjoy that sound system!
When it detects a signal it sends a big thump to the subwoofer and makes that pop sound. Using the remote out on the LC2i to the amp helps minimize it...
Do I need to use the actual speaker wire or can I T-off the speaker wire and plug in the new wire to the LoC? Thus the speaker wire is still connected to the speaker and is playing.
I have an Lc2i with an arc-1 remote. I made sure to adjust the device properly without the remote plugged in, The maximize light does not come on. So why do my subwoofers make a popping sound when I turn the knob up on my acr-1?
I have a 2012 Lexus ES 350 with Nav but without Mark Levinson. The bass rolloff isn't a plateau. It seems like it selectively reduces bass at different levels throughout the song. If I used an LC2i pro, would the bass still be choppy since it amplifies the bass signal from the input?
Great video, I love it. but what about if I want to connect only one single speaker cable with R+/L- to the LC2i speaker input, should I connect it to L+/L- or R+/R-?
We generally recommend bringing in your single speaker wire in to the left input (where GTO Signal Sensing lives) then jump that signal (+ to + and - to -) to the right input.

My sub amp keeps turning on and right back off while the truck and radio is off. It's an f150 running the lc2i in sensing mode controlling my sub amp remote wire. Any ideas?
Why does the lc2i put out signal at power on with the volume all the way down? You can see it in the RTA in the video @ 2:52.I can hear it, through my woofers. it’s a low hum!
Generally, this is due to most source units still putting out some signal, even with the volume all the way down. If you want to eliminate this, you can use a true turn on lead rather than using the signal sensing GTO turn on. Many times the hum heard in demo/training videos is produced by the 110v to 12vdc power supply, which wouldn't be an issue in an actual vehicle, of course.
Does anyone know how long the LC2i will stay on after the vehicle is turned off if I am using GTO? I have another brand LOC and it keeps my amplifier on for 10 minutes after the factory stereo is turned off. I looked in the manual for the LC2i, but I find no information on time out when using GTO. thanks
Question? When hooking up speaker inputs, does it matter what stage you use to hook up the lc2i! Like does the product need to be hooked up to the front stage wiring or rear? Does it matter?
Good question! It really depends on what you're using the LC2i for. If you are just adding a subwoofer amplifier/sub, then it really doesn't matter, so long as the signal you tie into has enough bass information present. If you are using the LC2i to add a full range 2ch or 4ch amplifier, the same applies. You would just want to be sure to tie into a signal that has the correct audio information present. Also, be aware that depending on what channels you use for signal, your fader may affect the output of your aftermarket amplifier/subwoofer.

How did you build turn out? If you dial down the bass from the head until to protect your "stock" speakers, does it also kill the bass coming out of the sub?
I have a gm kicker subwoofer installed from dealer. I want to add a soundstream bx-20z digital bass reconstruction processor. To controll the bass better for songs that dont hit as good. But I got it all connected a rememberd the kicker amp takes a high input from the left front speaker. And the output from the soundstream is a low line level output. Can the lc2 bring up the volume output enough for the kicker amp to work? The kicker amp has dip switches on the bottom do you know anything about the settings by chance?
Say if i wanted to get all new speakers, would I have to tap into all the factory speaker wires in order to get them to sound good with the aftermarket amp? I know most people just use 1 for the subwoofer install. Any help would be greatly appreciated. Thanks.
So I get that you pull signal from the existing speaker wire. But does it matter if it's before or after the factory amp and if the factory amp only powers the factory sub can I pull the signal from the inputs of the factory amp so I could remove it from the vehicle or should I get it from the rear speakers?
If you're only using the LC2I for an aftermarket sub, then the best place to tap into the speaker would be at the high level sub input.On my f30 bmw I was never able to get the lc2i to read the preamp signal coming from the head unit. On certain factory stereos, the head unit needs to see a load. The lc2i pro has an adjustable load feature, but the unit shown here does not.
Generally speaking, in most all vehicles, you'll want to obtain your signal for the LC2i or LC2i PRO from the output side of the factory amplifier. A line output converter like these is taking a high level signal and converting it to a low level signal. So chances are, you won't want to use the low level signal going into your OEM amp for signal. You'd end up with little to no volume.
You could use either one, but many times the front door speakers have a more useable frequency range and your aftermarket system will often sound better using that front door signal rather than the ohm sub signal. You could certainly try it with either and compare though, it won't hurt anything.
I installed my system, JL 12” with built in amp, lc2i Sounds good and clean, however once I start driving, specially on low speed, I head bass lines, consistant or come n goes. This is even when music is off On n off.. can’t wrap my head around where this is coming from
It's so hard to find a damn video. Where someone explains. What speaker wires you really need to hook up? If you're just doing a subwoofer, I've read that you only need to hook up one pair because it's mono, but I always see four wires going into that the speaker input. No one explains that at all, ever, never.
Bass is not always mono, even if it doesn't make sense. Some tracks will sometimes favor right channel, other songs will favor left channel, and i noticed this when i set stereo subs to my home audio system. When you connect both channels to lc2i, i suspect, you get a proper mono, so your bass will work the same no matter how the song is mastered.
Not sure I am clear on your question, can you clarify what you are wanting to do? Or if you'd rather, you always contact us directly at www.audiocontrol.com/contact/
I bought the Lc2i and I like it a lot. Diagram on paper shows you can install another amp for highs. I’m looking for install directions on that because I have factory amp and I can’t find any info about it ... I’m using already both rear speaker wires to power the Lc2i from behind factory radio... I would like to install a smaller 4 channel because stock interior speakers are not loud enough even after swapping door speakers. Can you point me to the right direction ?
Does the AccuBASS restorer require a full range signal to work, or I can I just use the factory amp subwoofer speaker cables which would only have sub level frequencies?
Mark, Do both speaker inputs need to be connected for the lc2i to turn on with the gto feature?? I only have access to one speaker at the moment to tap into.
If i want to run a mono amp for new sub only. Do I have to go through the factory deck, or does the hookup to the loc happen after the factory amp? I want to keep the factory amp running the stock speakers. I don't want to pull out my factory deck. Hoping it gets hooked up from the amp? Anyone know?
All of our products can accept signal from the outputs of an OEM amplifier. So if your vehicle has a factory amplifier, you can grab signal from it's outputs, feed that into our product's inputs, and end up with a nice clean RCA signal to send to your aftermarket subwoofer amplifier.
I installed a JBL BassPro SL2 powered subwoofer on my 2016 Volkswagen e-Golf (non Fender audio) by tapping the front speaker output wires and connecting them directly to the sub’s high level input. I noticed the head unit output now clips at a much lower volume and it gets unusually hot. It is almost impossible to set the sub amp gain as the levels are all over the place and slight changes to the amp gain cause the sub to cut in and out. I verified the polarity of all connections on both ends and everything seems alright. I would assume tapping into the speaker outputs effectively lowers the impedance seen by the head unit onboard amp causing it to go crazy. Wondering if using an Audiocontrol LC2i instead connecting directly to the sub’s high level input would make any difference.
You can grab signal from any speaker(s) in the vehicle that have enough bass in the signal presently going to them. Play a song with some bass in it, listen closely to each speaker (Put your ear up to it even?) and try to see if you can hear the speaker playing some bass. If you can, that speaker should be ok to grab your signal from. Remember, you don't have to disconnect the speaker either, you can just tap into the wires leading to it.

hello and good day, I recently installed the LCi2 into my car but when I close my door I get a progressive loud noise that comes out the subwoofer! Any ideas what I might be having an issue with?
When adjusting the gain knob on the LC2i for my aftermarket sub, is it the bass knob or the main knob?. Also should I have the gain on my amp all the way down when adjusting the gain knob on the LC2i?
Yes, start with the gain knob on your amplifier in it's lowest position. There are output controls on the top of the LC2i- MAIN and BASS. The MAIN knob controls the output level of the MAIN output RCAs and the BASS knob controls the output level of the BASS output RCAs. So the two knobs correspond to the two pairs of RCA outputs. Hopefully that makes sense- if not, give us a call sometime and we can help you through it.
@@AudioControlCar thanks that is exactly what I did. It is nice that my amp is getting a clean pre amp output signal. The gain on my amp is a 1/4" Turn away from being in the middle. It's good to know that I can always adjust the gain on the LC2i and amp some more if I want more bass
I’m having an issue with power. I have a constant 12 power hooked up but it turns on the lc2i and stays on with car off. Is there a certain way to hook up?
Sounds like your speaker wires are not hooked up properly. Fact: once there is any audio input into the LC2I, 12 volts is sent out of the 12 volts out.
I just installed the LC2i(with the GTO enabled), tapped into the rear left and right speakers for signal, connected the 12v+ and ground to the power and ground cables on the aftermarket AMP but I don’t seem to get the power light on all the time when I’m playing music even if the main dial is set to max… the power light keeps flashing instead of staying on all the time. What do you think that would be the reason? Thank you in advance!
You can use just one, if you need to, but you will then only get output from one of the RCAs. So, if you only have one channel of audio (one + and one -) to work with, we would recommend using short jumper wires to make sure that both the L and R inputs are populated. Check out this link where we explain this further in detail: www.audiocontrol.com/knowledge-base/factory-head-unit-mono-output-can-just-send-mono-signal-lc2i/
Sounds like you're using GTO to turn the unit on. Try bypassing GTO (using the jumper on the side of the unit) and then use a remote turn on lead to turn the unit on. This remote turn on can come from any +12v power source that turns on and off with the vehicle's ignition.
Yes im trying to use the gto but i thought itll turn off once you turn the car off? How would u bypass i see the two little prongs on the side but how would you hook it up beiing so little? Thank you for answering

@@dusaintel No, we meant it WILL absolutely work in a Mercedes. There is no reason why it wouldn't. If you are not able to get it to power on, and currently trying to use GTO to turn it on, you may have to run a switched +12v lead to the remote input.

Hello if I have a stock radio and after market amp 1 for door speakers and 1 for my sub can I use the matrix only? Or do I need a LC2i with the matrix. Thank u bro love ur videos
A light blinking of the maximized light is ok at high volumes. Preferably, the light would not be illuminated at all, but if it needs to flash on certain songs in order for you to get the desired output, that's ok.
Stupid question but Does this work with two amps? I see it works with the amp for subwoofers. Can I add my other amp for my front and rear door speakers? 2019 Honda Accord sport.
I’m very confused I had this installed by a friend who is knowledgeable but here is my question. It says it only puts out 400W per channel. I am only using the subwoofer channel right now. I have it connected to an amp that can put out up to 1400W. But since the audiocontroller can only put out 400W isn’t that limiting my amp to 400W?
The AudioControl LC2i (and most other AC products) can handle 400 watts of INPUT to their speaker level inputs and convert it into up to 9.5 volts of RCA low level output. Basically, taking an unusable factory signal and converting it into a usable signal your aftermarket amplifier can handle. The LC2i will have no effect on the actual wattage produced by your amplifier. It will work with a 100w amplifier or a 10,000 watt amplifier, but it will handle the signals the same way. So thankfully, your 1400w amp is not being limited in any way. You're on the right track, just getting a little mixed up in the specs/terminology. Hope that helps!
I have the premium Bose in my car currently with a passive kicker loc and today I will be installing the lc2i. It will work perfectly for it. I’ll get back with u and let u know more this afternoon after the install
Check your remote wire is properly installed into an ignition wire or a fuse that turns on with the vehicle when the key turns and then back off when you turn off the car.
Excelente informacion, me has sacado de muchas dudas, tengo un radio pantalla android y la calidad de audio no es muy buena... pensando en comprar uno de estos
My radio starts clipping at a little passed half way. Will intalling a LC2Ipro be better than using my amps high level inputs to get my amp to play at higher volume without blowing my sub?
Yes. The LC2i (or the LC2iPRO) will give you a cleaner, higher voltage signal to your amplifier(s), allowing you to get more from your amp/speakers with less distortion.
You can, although we recommend providing any AudioControl product with it's own power and ground. Occasionally, borrowing power and ground from the amplifier can result in noise or other issues.
Question- If I use the bass knob on the LC2i do I still need to run a bass know for the subwoofer amp or can I just run a bass knob for the amp itself?
In theory the LC2i is a cleaner source so boosting it before the amp might be more ideal, though I'm not 100% certain. But boosting a signal can add noise and with that could cause clipping and the like. So if the LC2i is indeed cleaning up and processing the audio, boosting it there might be where you'd want to do it while keeping the amp neutral.
MidnightMarrow the Bass knob for both are just attenuators. They don’t actually boost anything at all. Maxed out they just match whatever signal the output knob is set to. So the addition of one would just give you the option to lower output at the twist of a knob.
You could... Or you could use our DM-608 DSP processor and get all of that in one product. Our DM-608 and our DM-810 processors both have AccuBass (used to compensate for bass rolloff) built in.
It sure can! It is designed so that both sets of outputs are always functional. No need to switch them on/off or anything like that. Just plug in your RCA's front the LC2i to your amplifier(s) and go.
I've had this for a few years and since day one the gain knob does absolutely nothing. No volume change at all. The optimize light never comes in no matter where the gain knob is set. I think this is a lemon , sounds no different then my 20 dollar pac loc
@@RedBeardRebass nope hooked up correctly. I didn't realize that the bass adjustment was not actually a bass adjustment but s gain knob for the bass rca output. The gain adjustment is actually the gain for the main rca output. Kind of a confusing way of labeling the adjustments but I get it now. Once I went back and messed with it it I figured it out and optimized light started to come on. So far so good.
Thank you for the kind words. For power/ground/remote/speaker level input wiring, we recommend 14-22g wire, depending on the length of the wire run. Typical car audio primary wire will be 14-16g, and will work just fine.
Generally, just one pair for signal will be fine, when only adding an aftermarket subwoofer. If you want the OEM woofer to remain active, then just tap in. If you'd like to eliminate the OEM woofer and only have the aftermarket sub playing (recommended) then disconnect the OEM woofer completely. Hope that helps!
@@AudioControlCar so I would need to disconnect the oem subwoofer and run both speaker wires to get the full potential out of the aftermarket sub??? I'm running a apocalypse AAB-2900.1D and a apocalypse 270 15 d2 and I'm having the same problem at half the halfway point on the bass knob
@@adlerdefender8067 If you please, why wouldn't the y-adapters be sufficient in this case? I'm just about to do this exact thing. Thank you in advance.
Shouldn't be an issue, from what we understand of Kicker's Key technology. The LC2i's BASS outputs are set at 30hz-1khz, and the MAIN output is full-range, from 30hz-20khz. Of course, all of this will depend on the signal being fed to the inputs of the LC2i.
@@AudioControlCar That seems inconsistent with the instruction in the video. At 6:45, the video says you get the full frequency range from both Main and Bass outputs. Is this incorrect?
@@jayholt2101 If the amp and LC2i are close by, you can connect the 12v into the port of the amp itself as it's coming off the battery already. No need to run long lines for both. Also because the LC2i has the GTO feature, you also connect the remote OUT from the LC2i to the remote in of the amp and once the device detects signal from the left channel, it will turn itself on as well as the amp you've connected to it!
so I have 4 speakers (2 front and 2 back) and a subwoofer in my car. How do I connect all of the 4 speakers with only those 2 outputs? and then the bass will be connected to 1 output? I'm a bit confused how's the connection can be done..
The LC2i is a 2ch device, so it is generally used to add a bass amplifier & subwoofer to a factory sound system. It does however have an additional set of outputs, labeled "MAIN". So... if you feed signal into the LC2i that is full range, meaning it has highs, mids, and low frequencies present, you could use the bass output to a sub amp and the main output to a 2ch or 4ch amplifier. Then, you would connect your speaker wires to the outputs from your amplifier(s). In the scenario of a vehicle with front and rear speakers, you would lose the ability to fade front/rear. If you would like to amplify all of the vehicles speakers, as well as maintain the ability to fade, you would want to use an LC6i, LC7i, LC8i, DQ-61, etc. etc. etc.
@@AudioControlCar - Thank you that helps a lot. Just one last question, I have a factory "premium amplifier" that comes with my audio setup. So when I do the connections to the "speaker inputs in the LC2i". Do I connect the signal that comes directly from the HU? or after it gets amplified?

But I got it all connected a rememberd the kicker amp takes a high input from the left front speaker. And the output from the soundstream is a low line level output. Can the lc2 bring up the volume output enough for the kicker amp to work? The kicker amp has dip switches on the bottom do you know anything about the settings by chance?
Say if i wanted to get all new speakers, would I have to tap into all the factory speaker wires in order to get them to sound good with the aftermarket amp? I know most people just use 1 for the subwoofer install. Any help would be greatly appreciated. Thanks.
So I get that you pull signal from the existing speaker wire. But does it matter if it's before or after the factory amp and if the factory amp only powers the factory sub can I pull the signal from the inputs of the factory amp so I could remove it from the vehicle or should I get it from the rear speakers?
If you're only using the LC2I for an aftermarket sub, then the best place to tap into the speaker would be at the high level sub input.On my f30 bmw I was never able to get the lc2i to read the preamp signal coming from the head unit. On certain factory stereos, the head unit needs to see a load. The lc2i pro has an adjustable load feature, but the unit shown here does not.
Generally speaking, in most all vehicles, you'll want to obtain your signal for the LC2i or LC2i PRO from the output side of the factory amplifier. A line output converter like these is taking a high level signal and converting it to a low level signal. So chances are, you won't want to use the low level signal going into your OEM amp for signal. You'd end up with little to no volume.
can i use stock signal from my stock sub on my 13 ram 2500 to lc2i?? or it have to be from door speakers?
You could use either one, but many times the front door speakers have a more useable frequency range and your aftermarket system will often sound better using that front door signal rather than the ohm sub signal. You could certainly try it with either and compare though, it won't hurt anything.
I installed my system, JL 12” with built in amp, lc2i
Sounds good and clean, however once I start driving, specially on low speed, I head bass lines, consistant or come n goes.
This is even when music is off
On n off.. can’t wrap my head around where this is coming from
Great video and explanation Mark, but I have one question: What alternatives would there be next to the LC2i from other brands ?
It's so hard to find a damn video. Where someone explains. What speaker wires you really need to hook up? If you're just doing a subwoofer, I've read that you only need to hook up one pair because it's mono, but I always see four wires going into that the speaker input. No one explains that at all, ever, never.
Did you ever happen to figure that out?
Bass is not always mono, even if it doesn't make sense. Some tracks will sometimes favor right channel, other songs will favor left channel, and i noticed this when i set stereo subs to my home audio system.
When you connect both channels to lc2i, i suspect, you get a proper mono, so your bass will work the same no matter how the song is mastered.
so when you install this to the factory speakers, where do you hookup the RCA if there is the factory amp?
Not sure I am clear on your question, can you clarify what you are wanting to do? Or if you'd rather, you always contact us directly at www.audiocontrol.com/contact/
Can the lc2 work if i get signal from one single speaker??
Yes. Just parallel the plus and minus at the LC2I inputs.
I bought the Lc2i and I like it a lot. Diagram on paper shows you can install another amp for highs. I’m looking for install directions on that because I have factory amp and I can’t find any info about it ... I’m using already both rear speaker wires to power the Lc2i from behind factory radio... I would like to install a smaller 4 channel because stock interior speakers are not loud enough even after swapping door speakers. Can you point me to the right direction ?
Same here I'm trying to figure that out too. I think we would have to look for the door speakers wire and connect to the high amp.
Can I disconnect the stock sub, use those wires to the lc2i, set up the lc2i with the amp and run an after market sub JUST for bass ?
Yes
So I setup my lc2i changed nothing about the setup except vehicles, and now with my stereo volume at 0, my subs still hit. Why?
Does the AccuBASS restorer require a full range signal to work, or I can I just use the factory amp subwoofer speaker cables which would only have sub level frequencies?
Exactly what I’m wondering
Mark, Do both speaker inputs need to be connected for the lc2i to turn on with the gto feature?? I only have access to one speaker at the moment to tap into.
If i want to run a mono amp for new sub only. Do I have to go through the factory deck, or does the hookup to the loc happen after the factory amp?
I want to keep the factory amp running the stock speakers. I don't want to pull out my factory deck. Hoping it gets hooked up from the amp?
Anyone know?
lakermd before the factory amp, it’s going to amplify your amp with cleaner power
All of our products can accept signal from the outputs of an OEM amplifier. So if your vehicle has a factory amplifier, you can grab signal from it's outputs, feed that into our product's inputs, and end up with a nice clean RCA signal to send to your aftermarket subwoofer amplifier.
I installed a JBL BassPro SL2 powered subwoofer on my 2016 Volkswagen e-Golf (non Fender audio) by tapping the front speaker output wires and connecting them directly to the sub’s high level input.
I noticed the head unit output now clips at a much lower volume and it gets unusually hot. It is almost impossible to set the sub amp gain as the levels are all over the place and slight changes to the amp gain cause the sub to cut in and out.
I verified the polarity of all connections on both ends and everything seems alright. I would assume tapping into the speaker outputs effectively lowers the impedance seen by the head unit onboard amp causing it to go crazy.
Wondering if using an Audiocontrol LC2i instead connecting directly to the sub’s high level input would make any difference.
If I'm only hooking up my subwoofer (with amp) to the lc2i where do I get the speaker wire from?
You can grab signal from any speaker(s) in the vehicle that have enough bass in the signal presently going to them. Play a song with some bass in it, listen closely to each speaker (Put your ear up to it even?) and try to see if you can hear the speaker playing some bass. If you can, that speaker should be ok to grab your signal from. Remember, you don't have to disconnect the speaker either, you can just tap into the wires leading to it.

hello and good day, I recently installed the LCi2 into my car but when I close my door I get a progressive loud noise that comes out the subwoofer!
Any ideas what I might be having an issue with?
Can you use the Lc2i pro for 4 door speakers and an amp?
When adjusting the gain knob on the LC2i for my aftermarket sub, is it the bass knob or the main knob?. Also should I have the gain on my amp all the way down when adjusting the gain knob on the LC2i?
Yes, start with the gain knob on your amplifier in it's lowest position. There are output controls on the top of the LC2i- MAIN and BASS. The MAIN knob controls the output level of the MAIN output RCAs and the BASS knob controls the output level of the BASS output RCAs. So the two knobs correspond to the two pairs of RCA outputs. Hopefully that makes sense- if not, give us a call sometime and we can help you through it.
@@AudioControlCar thanks that is exactly what I did. It is nice that my amp is getting a clean pre amp output signal. The gain on my amp is a 1/4" Turn away from being in the middle. It's good to know that I can always adjust the gain on the LC2i and amp some more if I want more bass
@@AudioControlCar Does that mean we can leave the gain all the way down on the amp and use just the lc2i to adjust gain?
Lc2i pro newer model is what I use. All on the pro model you can easily see and make changes on front, love it
I’m having an issue with power. I have a constant 12 power hooked up but it turns on the lc2i and stays on with car off. Is there a certain way to hook up?
Sounds like your speaker wires are not hooked up properly. Fact: once there is any audio input into the LC2I, 12 volts is sent out of the 12 volts out.
I just installed the LC2i(with the GTO enabled), tapped into the rear left and right speakers for signal, connected the 12v+ and ground to the power and ground cables on the aftermarket AMP but I don’t seem to get the power light on all the time when I’m playing music even if the main dial is set to max… the power light keeps flashing instead of staying on all the time. What do you think that would be the reason? Thank you in advance!
Love the vid! But do i have to hook up both speaker inputs or can i just use one?
You can use just one, if you need to, but you will then only get output from one of the RCAs. So, if you only have one channel of audio (one + and one -) to work with, we would recommend using short jumper wires to make sure that both the L and R inputs are populated. Check out this link where we explain this further in detail: www.audiocontrol.com/knowledge-base/factory-head-unit-mono-output-can-just-send-mono-signal-lc2i/
Good question, excellent answer, thank you
Hello, can you hook an epicenter after the LC2I ? If so it would go to the main or subwoofer ? Regards
What settings is door Speakers
With lc2i can you add a epicenter?
Yes you can
You sure can. In case you're wondering, the order will be: source unit>LC2i>Epicenter>amplifier(s)
Thanks 😊
I have a question regarding the lci2 not turning off once the motors off? Can you please help?
It power up right away after you plug your speaker wires to your main back speakers even though the motors off
Sounds like you're using GTO to turn the unit on. Try bypassing GTO (using the jumper on the side of the unit) and then use a remote turn on lead to turn the unit on. This remote turn on can come from any +12v power source that turns on and off with the vehicle's ignition.
Yes im trying to use the gto but i thought itll turn off once you turn the car off? How would u bypass i see the two little prongs on the side but how would you hook it up beiing so little? Thank you for answering
What do I do if my LC2i isn’t shutting off?
That means you have noise on your speaker lead inputs if I am understanding you correctly (not good). Most likely it is installed incorrectly.
Would it work on a mercedes vehicle?
Absolutely!
@@AudioControlCar im having issues. It wont power up. Im tapping into the rear oem harmon/kardon subwoofer. There is 4 wires. On the LC2i: I have - green into positive, grey into speaker negative, red - +12v, and black - ground. Then I switched black into rem. still nothing. Please advice how i should wire it?
@@AudioControlCar you meant Absolutely No right? Sorry I misunderstood
@@dusaintel No, we meant it WILL absolutely work in a Mercedes. There is no reason why it wouldn't. If you are not able to get it to power on, and currently trying to use GTO to turn it on, you may have to run a switched +12v lead to the remote input.

Question...is the maximized light supposed to blink when bass is hitting?
no
Only if you have the gain set too high.
A light blinking of the maximized light is ok at high volumes. Preferably, the light would not be illuminated at all, but if it needs to flash on certain songs in order for you to get the desired output, that's ok.
Stupid question but Does this work with two amps? I see it works with the amp for subwoofers. Can I add my other amp for my front and rear door speakers? 2019 Honda Accord sport.
Yes. You can use a "Y" RCA cable to run 2 amp inputs.
Can I just jump power off of the amplifier and jump ground to the ground on the amp??
Many do this with fine results, but we generally do not recommend it.
I’m very confused I had this installed by a friend who is knowledgeable but here is my question. It says it only puts out 400W per channel. I am only using the subwoofer channel right now. I have it connected to an amp that can put out up to 1400W. But since the audiocontroller can only put out 400W isn’t that limiting my amp to 400W?
The AudioControl LC2i (and most other AC products) can handle 400 watts of INPUT to their speaker level inputs and convert it into up to 9.5 volts of RCA low level output. Basically, taking an unusable factory signal and converting it into a usable signal your aftermarket amplifier can handle. The LC2i will have no effect on the actual wattage produced by your amplifier. It will work with a 100w amplifier or a 10,000 watt amplifier, but it will handle the signals the same way. So thankfully, your 1400w amp is not being limited in any way. You're on the right track, just getting a little mixed up in the specs/terminology. Hope that helps!
I have a question. I know this has a control knob but my amp has one too. Do I have to install both or how does that work? Thanks
No. Just use your original bass control knob.
Would an LC7i work better for a premium bose system or would the LC2i I have be sufficient enough?
I have the premium Bose in my car currently with a passive kicker loc and today I will be installing the lc2i. It will work perfectly for it. I’ll get back with u and let u know more this afternoon after the install
Good stuff brother. I've recently installed an lc2i with a crossover and a 4 channel Boss amp. My question is why are they staying powered on?
Check your remote wire is properly installed into an ignition wire or a fuse that turns on with the vehicle when the key turns and then back off when you turn off the car.
Awesome video and great info to do my first custom install 🤟🏽
Excelente informacion, me has sacado de muchas dudas, tengo un radio pantalla android y la calidad de audio no es muy buena... pensando en comprar uno de estos
My radio starts clipping at a little passed half way. Will intalling a LC2Ipro be better than using my amps high level inputs to get my amp to play at higher volume without blowing my sub?
Yes. The LC2i (or the LC2iPRO) will give you a cleaner, higher voltage signal to your amplifier(s), allowing you to get more from your amp/speakers with less distortion.
@@AudioControlCar increasing the Bass level on LC2i is better than increasing the gains on the amp? Also, how do I tune LPF?
@@kuanliu3383 That is my question as well!
Why does my light say maximized and its not working
Can you link the 12v and ground from your amp?
Yes
You can, although we recommend providing any AudioControl product with it's own power and ground. Occasionally, borrowing power and ground from the amplifier can result in noise or other issues.
@@AudioControlCar what problems does it cause ?
Can I connect 2 amps voice and bass to this converter??
Yes
Yes, you sure can! The LC2i has both a BASS and a MAIN output, perfect for doing exactly what you asked about.
Question- If I use the bass knob on the LC2i do I still need to run a bass know for the subwoofer amp or can I just run a bass knob for the amp itself?
You can run on knob from either one that you want. You don’t need one on both. Either or do the same exact thing.
In theory the LC2i is a cleaner source so boosting it before the amp might be more ideal, though I'm not 100% certain. But boosting a signal can add noise and with that could cause clipping and the like. So if the LC2i is indeed cleaning up and processing the audio, boosting it there might be where you'd want to do it while keeping the amp neutral.
MidnightMarrow the Bass knob for both are just attenuators. They don’t actually boost anything at all. Maxed out they just match whatever signal the output knob is set to. So the addition of one would just give you the option to lower output at the twist of a knob.
Can I use the lc2i for the base roll off & a dsr1 for the Dsp at the same time?
You could... Or you could use our DM-608 DSP processor and get all of that in one product. Our DM-608 and our DM-810 processors both have AccuBass (used to compensate for bass rolloff) built in.
Lc2i has a built in high pass filter at 33hz. The pro does 20hz.
What do you mean by this? The lc2i won’t play under 33hz?
@@xxah54nxx it means it falls off rapidly under 33hz. I changed it out for the pro and the lows are much better.

Can the LC2i run both main and bass output at the same time?
It sure can! It is designed so that both sets of outputs are always functional. No need to switch them on/off or anything like that. Just plug in your RCA's front the LC2i to your amplifier(s) and go.
I've had this for a few years and since day one the gain knob does absolutely nothing. No volume change at all. The optimize light never comes in no matter where the gain knob is set. I think this is a lemon , sounds no different then my 20 dollar pac loc
sounds like it's not hooked up correctly
@@RedBeardRebass nope hooked up correctly. I didn't realize that the bass adjustment was not actually a bass adjustment but s gain knob for the bass rca output. The gain adjustment is actually the gain for the main rca output. Kind of a confusing way of labeling the adjustments but I get it now. Once I went back and messed with it it I figured it out and optimized light started to come on. So far so good.
Do you recommend hooking up both rear speakers or can I us one?
Need to hook up both for stereo left and right 👍
Hey been waiting and great video love your work keep the kitchen hot man
Awesome video! What's the best gauge/ type of wires to use to connect speakers, power, ground and remote?
Thank you for the kind words. For power/ground/remote/speaker level input wiring, we recommend 14-22g wire, depending on the length of the wire run. Typical car audio primary wire will be 14-16g, and will work just fine.
Great video very informative. I have a question . My factory subwoofer is a dual voice coal. Should I tap into all 4 wires or just 2 ?
Also should I cut them or just tap into them ? 2011 Toyota 4Runner JBL subwoofer
Generally, just one pair for signal will be fine, when only adding an aftermarket subwoofer. If you want the OEM woofer to remain active, then just tap in. If you'd like to eliminate the OEM woofer and only have the aftermarket sub playing (recommended) then disconnect the OEM woofer completely. Hope that helps!
@@AudioControlCar so I would need to disconnect the oem subwoofer and run both speaker wires to get the full potential out of the aftermarket sub??? I'm running a apocalypse AAB-2900.1D and a apocalypse 270 15 d2 and I'm having the same problem at half the halfway point on the bass knob

Nice video. Can I run a Kicker 600.1 out of the bass rca’s and a Kicker Key 200.4 out of the other set? No issues with tuning the “Key”?
Shouldn't be an issue, from what we understand of Kicker's Key technology. The LC2i's BASS outputs are set at 30hz-1khz, and the MAIN output is full-range, from 30hz-20khz. Of course, all of this will depend on the signal being fed to the inputs of the LC2i.
@@AudioControlCar That seems inconsistent with the instruction in the video. At 6:45, the video says you get the full frequency range from both Main and Bass outputs. Is this incorrect?
Where do you get the 12v power from???
Run a 18gauge wire with a in line 1amp fuse straight from the battery.
@@jayholt2101 If the amp and LC2i are close by, you can connect the 12v into the port of the amp itself as it's coming off the battery already. No need to run long lines for both. Also because the LC2i has the GTO feature, you also connect the remote OUT from the LC2i to the remote in of the amp and once the device detects signal from the left channel, it will turn itself on as well as the amp you've connected to it!
so I have 4 speakers (2 front and 2 back) and a subwoofer in my car. How do I connect all of the 4 speakers with only those 2 outputs? and then the bass will be connected to 1 output?
I'm a bit confused how's the connection can be done..
The LC2i is a 2ch device, so it is generally used to add a bass amplifier & subwoofer to a factory sound system. It does however have an additional set of outputs, labeled "MAIN". So... if you feed signal into the LC2i that is full range, meaning it has highs, mids, and low frequencies present, you could use the bass output to a sub amp and the main output to a 2ch or 4ch amplifier. Then, you would connect your speaker wires to the outputs from your amplifier(s). In the scenario of a vehicle with front and rear speakers, you would lose the ability to fade front/rear. If you would like to amplify all of the vehicles speakers, as well as maintain the ability to fade, you would want to use an LC6i, LC7i, LC8i, DQ-61, etc. etc. etc.
@@AudioControlCar - Thank you that helps a lot. Just one last question, I have a factory "premium amplifier" that comes with my audio setup. So when I do the connections to the "speaker inputs in the LC2i". Do I connect the signal that comes directly from the HU? or after it gets amplified?
