I thought this shop was trying to get more money out of me but i see I actually need it for my factory radio . Appreciate you clearing it up
This guy's install and explanation videos are the best. At this point I watch for entertainment purposes
I like that you said that because after finding the help I've bee needing , I think I'll start showing up more often.
This is the only video I've seen that explains how the components work. Very helpful! Thanks!
Glad it was helpful!
Outstanding video. Perfectly explained. Thank you very very much.
I just subscribed. You have made wiring and terminating less scary for many of us.
Your videos mean a lot. Thank You!
Awesome, thank you!
Nice video, very professional and informative. Thanks for taking the time to make a great video!
Glad it helped!
This helped me to do this. Home theater AV receiver --> frontal main speakers --> LOC --> stereo amplifier --> One pair of speakers. Now I can use only one pair of main speakers for music and for movies and games. I don't see this solution very often. Thank you.
Great video! Helped me a lot with my amp install. Thanks!
Thank, buddy for this very informative video..... I like how thorough you are with your explanations.
Glad you enjoyed it Tony!
I do have a question though. If I'm just using the high level straight from the amplifier itself, do I need to have the remote wire extended all the way to the factory stock stereo? I guess what I'm asking is do high level installation have a trigger for remote turn on so that I won't have to connect it to the head unit (like the LOC here)?
Great video super helpful thank you
This helped more than any other video out there. Dope
💪💪💪
You are the best man, thank you. I have learnt a lot.
Glad you found it helpful!
Couldn't have timed this better. You guys have have saved me a lot of time. Please spare a few minutes for my complicated question but before that;
Amazing job done by the presenter explaining all the confusing things in layman term's. Was a Subscriber earlier but I tried subscribing again 😇✌
After countless hours of sleepless nights and hours of research with a tight budget, I wanted to have the best setup which suited my needs. Clear Full Range Music(EQ control) with Accurate BASS. Have bought a 840watt's Blaupunkt 4 channel GTA 470 Digital Sound Processor Amplifier , JBL CSX-1400BP 12" Subwoofer, PAC PDLC 21 Active 2 channel LOC, Surge F8 Flo True 8AWG 800W AMP wiring kit which is on its way. I'm hooking the the 2 channels of the Amp to the front speakers and the 2 bridged channels to the Sub.
Since I'm having a DSP Amplifier with various settings such as X-over control, Subsonic control, Phase control, Delay control etc. Does the front speaker signals give full range output i.e If I tap into the front speaker signals with the LOC, will I be able to achieve a full range surround sound system in my car with DSP control function working properly?
Was thinking about a 4 channel LOC but thought it would be useless since I'm using only 2 front channels of the amplifier for speaker and remaining 2 for a Sub. I can use the PAC PDLC21 with a low output gain settings since it can pump out 10V unlike a passive LOC and Adjust the gain in the Amplifier to adjust the Fader setting to achieve surround sound from a 2 channel LOC.
My stock HU is a 4 speaker outs with a stock 6 speaker(2 tweeters+4 mid speakers) setup. I'm planning to change my Stock front speakers too, Any suggestions for the type (and brand) of front speakers which will suit my setup?
Being that this a factory 4 channel with tweeter, it's likely that you have full range output on all four speakers, we never truly know without testing it. If I were to wager, I think your setup will be fine as described.
Quality Mobile Video Can I use a two channel LOC hooked up to a mono block amp with one sub woofer? Or is there an LOC for one channel apps?
I wish you were in my area with this kind of professionalism
Great video!!!! I'm so glad you showed the guts of the LOC and explained the internal parts. It really helps people like me to understand better. Thank you !!
Wooo! Glad it helped you out!
You are the real MVP for this video I tapped my Bose base speaker and all I get it base in my mids I'm gonna try the lci2
Woo!
Very clear and great video.
Thanks!
Finally a clear answer on the yellow and black wires! No other videos cover that.,
Glad it helped Chris!
You should always keep that in the back of your mind. That when in most cases, when dealing with car audio a yellow is always gonna be a constant. Twelve volt and black more than likely most of the time is a ground.
Thanks for the video. Very informative. I have a 2013 Cadillac XTS, in which I'm trying to hook up two 12 inch subs to the Cadillac's CUE infotainment factory head unit.
Glad it helped!
awesome overview!
:)
This helped a lot! I got a used 2016 buick regal pre wired for a amp and sub and got lost when I saw the loc. I thought I was doing something wrong.
So helpful took so much stress away watching this video.
Thank you so much for this vid! The PAC LOCs in particular was a revelation(the load circuits!) and will solve a big problem for me whereby I lost fader capability when connecting an aftermarket amp to stock vw head unit :D
Glad it helped!
Awesome. Thanks for this. It definitely helps
Awesome!
Phenomenal video brother good job
Much appreciated
this has saved my bacon, Thanks!!!!!
really good video man
Appreciate it!
He said 20,000 KHz....lol Just bustin' your chops, man; Your vids are awesome!! Sparks in Daytona
Thanks!
Best LOC video I've found, extremely informative. Only one question remains for me: Is there a limit to the length of wire ran on either side of the LOC? Should the speaker level side be short and very close to the head unit, or should the low level side be short with the LOC closer to the amplifier? Is there a medium, or is it not important? I see how yours are setup and I'll mirror that for now. Thank you very much.
Ok
In addition to running speaker wires from the LOC to the car speaker wires, I just realized I ran an additional set on both car speakers and ran them into the speaker terminals on the sub amplifier obviously where the sub speaker wires go into. The sub works and sounds great I just don’t know if there’s any issues to having another set of wires on each side of the car speakers running into the speaker terminals on the sub amplifier
Great video, if I were wiring my LOC behind the radio where would I get my power from?(yellow cable)
Glad you guys operate near to where I live. I'm going to call soon someday to see if you guys install stuff too, and not just sell it online(it does sound like you guys do install). Thanks!
excelente muy interesante ese dispositivo me necanta ese video, esta muy bien explicado, le sugiero colocar un fondo musical mas bajo..para oir mejor,
Hi
Great video👍
I have a 2017 Honda Civic Rs hatchback 1.5T(Australian model) which is probably equivalent to a touring or sports touring except without navigation.It has a premium factory stereo with 12 speakers including a factory subwoofer and factory amplifier.
I have the pioneer gm-d8601 monoblock amp which accepts high level speaker inputs up to 16.5v and therefore don’t need a loc.
Installers here in Australia can’t give me a straight answer about installing this amplifier with a aftermarket subwoofer.
This is what they tell me:
1)Use the existing factory subwoofer wires straight to the pioneer amp. These wires are coming straight from the factory amplifier and therefore watts going to factory subwoofer is unknown.
2)tap into speaker wires from behind the factory head unit and straight to the pioneer amp for the signal.
3)I can’t get a signal directly from behind the factory head unit because the signal is digital and not analog and therefore I need to get a signal for the pioneer amplifier after the factory amp. Meaning I can’t bypass the factory amplifier.
Any help advice would be appreciated. Seems like installers here down under are not that knowledgeable.
Cheers mate

im planning on doing something like this on my 00 323i. My rear deck speakers are blown as of right now and im thinking of just using the wires from that, and putting an loc in my trunk with the rear deck speaker wires running to it. Then running rca to my amp. Do you think it would work?
Can you post a video on how to set the gains on these
Amazing this is professional engineering technical work, for like this professional work you must pay any amount of labor charges. Excellent explanation.👍👍👍
Question.
Car with fiber optic amplifier systems to upgrade sound unit to aftermarket Sony or alpine.. Etc how can used the original amplifier with fiber optic cable, or delete all systems or what the best solution or option I have.
Thanks man , I have a question. I tapped in to my factory subwoofer but my PAC LP7-2 won’t play a beat. I’m guessing it doesn’t pick up those frequencies right? Should I upgrade to a LC2-I
Makes sense now my line output converter never had a ground wire to cancel out the humming from my subs happens sometimes and other times I turn the car on doesn’t happen I have to get one with a ground wire
Very informative video! One question - how did you test for Full Range Output?
Roxshot Use a test tone disc and DMM.Test 40hz...400hz.....1000hz......4000 hz at the same volume level.If the voltage output is basically the same for each frequency then you've got a full range signal.If say 40hz has a much higher voltage reading than 400hz than that signal has a low pass filter on it....etc
nice video, a quick question, i have 2 amplifiers 1 for my door speakers which i understand for low line output converter is installed on stock radio, but for my subwoofer amplifier where do i connect signal wire for a low line output rca to my amp? thanks hope you can help
Hey guys thanks for all that information! I still have a question tho... I’m about to install a Kenwood 6 channel amp on my 2017 Honda Accord that has the 4 speaker only factory system, so far so good right... 4 channels from factory HU to the amp then out to 4 speakers... my question is, what channel from the factory stereo/hu should feed the subwoofer since all 4 are taken??
Do I split the signal from the LOC’s RCA output so I can feed the subs input rca on the amp? What do you recommend I should do?
If I get a six channel LOC I face the same problem only at the inverse.
What type of solution do you recommend? Your help is greatly appreciate it!!! :)
As a Formally Trained Audio Engineer and a guy who cut his teeth doing car stereos I thought that was actually a pretty good breakdown for folks that don't have an electronics background or a lot of inclination to get deep on how all this audio stuff works. I employed one of these adapters in a Bar where the Owner asked if I could run the output of his Jukebox (which only had a Left and Right External Speaker Output) into the speakers He had in the ceiling (or more correctly to the amp that powered those speakers) and it worked beautifully - also it's great because it mirrors the volume of its source relatively speaking. Not sure why this got so many thumbs down - I thought it was fairly spot on. Also for the record this doesn't replace the speakers in the circuit - it sits in parallel with the speakers (a "tap" so to speak) which keep the Ohm load correct to the amp - You'll have much more success than trying to completely use this device by itself without those speakers. - MM in Denver CO
Thanks bud!
Do you recommende LP7-2 over LP7-4? My question is if I want to keep the balance of my stock stereo with an Amp but with additional Amp to a Subwoofer.
OKAY this is what i needed so i did the same thing with my rear deck speakers and i had a high level output harnas for months. And today i wired the 4 wires to my LOC and connected it now my amp nor subwoofer will turn on
please help
Your amp using high level input probably had audio signal sense turn on. You will need to double check your owners manual to see if it is possible to have signal sense turn on using RCA inputs, if it doesn’t you need to run a remote turn on wire.
but I want to run an aftermarket kenwood amp what watts can I use with this rca
Does anybody make a video for people who need videos? Everybody skips the only part of the instruction I actually need.
I've been trying a reverse to this without much success, converting pre-out RCA from my head unit to line-level to feed the factory amplifier, it's good enough for me. Originally with the high-line output to the amp it was too loud, as you'd expect but now with the pre-out it's too quiet at full volume. Not sure how I can find a middle ground. The amplifier in the head unit should be good enough as it's a new high-end Alpine unit so I'm tempted to rip out the factory amp and install passive crossovers instead for my 12 speakers. Still considering my options.
I have similar setup as you. I have problem that playing music wakes amp, but playing radio does not. Do you have problem waking factory amp with aftermarket head unit?
I have a 2016 Chevy Silverado. IV installed everything and it works but how do I adjust the radio to maximize quality and bass?. Turn bass up or down? And then turn gain up on amp?. Not much tuning options on factory radio, Thank you for your time
Can i just go off the passenger rear speaker on my 14 dodge ram. Used the loc2. Just not sure if im not getting full range by not going on driver side as well
Hi, my 2018 honda fit seems to have pretty aggressive low frequency cut off on stock head unit as the bass is very lacking so im wondering if its going to affect the sound of the sub amp when using a LOC ?
If my aftermarket radio has a front rca output and a rear/SW output, would it be a good idea to use Y rca cables to split the signal so I can connect both the sub amp and the front and rear amp? Or should I convert the high level outputs to Low level RCA and use that as my outputs
So, I cut the right front speaker wires from the factory unit.. now I connect the wires to the LOC and then use the other side of the speaker wires and run it to the amp?
I am on my second p a c LP 7-2. My first was reading very low voltage. My second one did the same thing, I'm trying to target 2v but the highest reading is 0.017 ac.volts on both converters. I used two different multimeters with the same reading. My car is 08 Acura TL and I tapped into the rear speaker. I know for a fact I have it hooked up correctly. Do you know what's going on?
I will say, which he stated as well that the factory deck does make a difference in outputs signals to different speakers so go for whats best. I have a 2017 wrx and have had nothing but trouble so far with my system. First I bought the PAC LP7-2 and honestly sounded like crap. My sub didn't sound nowhere near what it sounded like I'm my truck with aftermarket deck and everything. So I purchased a Skorpion LOC which did help a lot more but still wasn't "clean" bass. Used the Skorpion LOC before in a different car and worked amazing But not for my wrx. Next step would be the audio control LC2i active LOC. Main reason for this long comment, any amp takes about 5 volts input signal to the amp. The PAC LP7-2 only puts out about 1.6 volts. Audio control LC2i puts out almost 7 volts! Little more than needed and for 40 bucks more the than PAC, you do the math. May be the reason why you might have sound quality issues as well. You pay for what you get. In some applications its perfect but others, no. Worked on car audio for 7 years now and learned to much crap on my own. Even the hard way. Hope this helps👍
I have a 2017 STI Base Model and I have been looking at upgrading my sound system. I went to many car audio shops in my area and I've been getting different recommendations from each of them. Anyway, I want to keep my stock head unit, so some of them recommended me to get an LC7 and some of them told me just to get this Line Output Converter. I am really confused on who should I listen to. I feel like some of them just want my money and don't really care what the outcome is gonna be for my sound set up. So idk if i wanna do just the LOC or an LC7.
@@BinaryBroadcast The speaker level inputs of an amp are the same thing as a LOC so I never understand why people use LOC's if their amps have HLI's?
If you're not getting a clean signal, then you're not getting a great crossover or the source signal doesn't possess the range needed for the output speaker.
Crossovers designate which frequencies go to which speakers, and are usually necessary to give an aftermarket system a truly "clean" sound. It will only allow the target speaker(s) to produce the specified frequencies.
Again, it also matters where the source frequencies are coming from.
So I want to put this set up "Rear speakers and a sub" with el 4 channel amp RockFord Fosfate R400. Do I need a 4 channel line output converter and the same process of tapping the rears? How do I wire for 4 channel tapping the rear
Im having a boooom if i cut off my radio do i need to ground the 2 brown wires on my PAC SNI-35 ADJUSTABLE 2 CHANNEL LINE OUT CONVERTER SPEAKER WIRE HI LOW RCA SNI35 ?
Quick question I got the kicker version of this loc which has the remote wire. But my question is, is it OK to tap into the stock OEM subwoofer connection? Is it too much power for that little device or will it be OK? It’s the stock amp and subwoofer plug in the back of the mega cab behind the seats . Just because it’s easy to access is why I’m asking
I have 1200watts Car Stereo, and I have 4stock car speakers, and I want to add 400watts woofer and 2-speaker 2way 800watts
...so total speakers are 7
.will.it works/connect to my stereo?
Do you have any experience with a Cadillac ATS with the premium Bose package on the CUE head unit? I'm trying to install two 12" kicker subs and a 1400W kicker amp
do you just connect the constant 12v to the power wire from the battery? and also connect it right to the ground connection on the amp itself?
I have a 2018 Accord lx. I took a monoblock amp and a Kicker L7 out of my Tundra that absolutely pumped I use the same line output converter that you have in the video with the remote turn on I kicked the gain all the way up on the line out converter and the amp and it barely puts any sound out I don't know what to do???🤯 I also disconnected the noise cancelling system behind the glove box but it's like the Accord does not put much bass sound through the rear speakers so I don't have a good enough signal I have no clue what to do I'm about to rip it all back out of the car
Do you know if the 2015 and up Dodge Chargers SXT rear speaker wires are full range? I want to connect Audio Control LC7i or DQ-61 so I can connect 3 amps each for high, mids and lows from the just rear speaker signal.
I have subs installed to my stock radio but now I have a aftermarket head unit was wondering how I use a universal bass knob without having any rcas going to the head unit since I still have my line output converter
I have a 2017 lexus is300 I wired the loc to the factory amplifer 8 inch woofer wires left and right together since I only have one 8inch factory sub. Will this be OK or would my signal be weak because I don't have a left amd right signal
I have the opposite problem. I have an aftermarket head unit with RCAs out and I would like to use a stock stereo I have sitting around because it fits the area. How do I do that?
I have a six speaker system, two tweeters in dash on 2015 Volkswagen Passat, do I need the fancy Lin out due to tweeters possibly being high level? Where do I go about finding this out?
Can you still use the PAC LP7-2 if you are tapping stock amplified 2ohm leads? replacing the 2ohm full range speakers with the LP7-2? Will this great an issue with the existing untouched existing 8 speakers.?
I've watched vids where they cut the wire right next to the factory stereo and then others that did your way. Can I connect the LOC directly from each speaker rather than cutting the factory harness? And do I have to connect all the speakers to the LOC?
Did you run the remote wire on the loc to the amp directly or are you finding another 12v source to connect it to ?
Yes what did you run the remote wire to? Most of the fuses in my car are constant Im curious to what fuse turns on when the ignition key is turned on. I have a 2007 cadillac escalade.
@@benkea445 I have a lexus with stock subwoofer I'm curious if I should run the loc from the stock woofer or to the door speakers
Ben Kea the fuse that says ACC but please be mindful those fuses are constant on one side and not constant on the other side. Took ten years installing stereos and replacing dead batteries before TH-cam was invented hahaha. Hope this piece of info helps, consider yourself blessed for coming across it. I know I was... Love you guys, Happy New Year 2020
I have the loc pro LP7-2. With this converter you can just connect the remote wire directly to the amp with out having to run a remote wire through your vehicle. It’s all just depends on which converter you have. Hope this helps
I hope u read and reply to my question. I have 2 channel stereo without line level out how do I use this device for add Com.
I have a 2011 murano with the factory bose amp and sub. Can I tap into the amp to hook up the loc? All I'm looking to do is add another amp and 12 inch sub. I would run separate power from the battery. Looking for some ideas thanks
I was hoping you were going to tune it. Im not sure the relation between the gain on my monoblock and the gain on the line out converter
Hey.
I want to install a 4ch amp and a Mono amp to a factory head unit. Could you please help me on how to install the LOCs for the same..
Couldn’t have explained it better 👍👍
Glad it was understood easily!
Amazing vid my speakers pop when I turn it up after turning up the volume. Also there is no bass to the subwoofer ( I’m only running a sub to a 4 channel amp) can you help me out?
How do you know if your amp can decipher hi and low from a simple rca split from a line output converter? What would be in description on amp ?
I have a 2016 Cadillac CTs vsport with Bose 13 premium speakers and factory amp my questions are what’s the best loc to use? I’ve tried the lc2i and keyloc on my old Cadillac ats when just adding a subwoofer, but if I wanted to change the door speakers and use a four channel amp, is there a way to bypass the factory amp or can I just replace the front speakers with some more high output speakers that I have, and keep the factory amp?
Can you make a video on how to run the remote wire the yellow and blue wire
i have a civic 2018 coupe. i have acces to rear really easy do you know if i have full powwr to rear? or i need to tap the front?
Installed this today. 2012 Malibu rear speakers. Loc will not shut off for 10 min tho I think it's the radio. I would understand if it was connected to front drivers due to chime. I may have to put mine on acc 12v
What if you have any aftermarket radio with one rca pre out can I still use the lp7-2?
If the blue Remout ON wire is connected to a constant power like in your installation, the amplifier will be ON all the time and may drain your car battery when the car is not running. Is it better to connect the blue wire to an "Accessory" or "Ignition" power?
I have a corolla 2015 with after market-powered sub. The part where you connected the remote turn on for the amp was on the LOC, I dont have an LOC on my arrangement just a powered sub.. if you can please help me with where to connect that? thanks
Are there any benefit of using powered LOC over non-powered LOC?
is there a LOC the can turn my factory radio two channel into 4 channel? or should I just get a 4 channel loc and t the wires together
Do you only need to use 1 speaker when tapping in to them? Or do you need to use 2 speakers? I have mine set up running off of my right front door speaker. But it’s seems that I am only getting single, or power, or very week response out of one of my subwoofers. Thanks in advance for any help!
Is it possible to run a line out converter off of a amplified speaker wire? I have a upgraded system in a factory car.
Hooked up a sub and amp to my factory dodge Dakota. Not using a LOC! I just spliced into my rear speakers on the door with speaker wire and converted the ends to RCA plugins. Seems to work fine. The bass hits. But when I turn up the volume quick it cuts out and loses bass. I then have to turn down bass on the radio for the sub bass to kick on again. Why is this happening? Thanks.
So you hooked up both rear speakers to the LOC?? I had mine installed "Profesionally" and they only hooked up the 1 side should I redo it to have both for better sound and quality? I have aftermarket rear speakers as well and a amp and sub, amp is only for the sub. TIA
Mono block amp? Is there an advantage to wire 2 rear speakers to the LOC or can i wire just 1 speaker output to both +and- of the LOC if just used for a Subwoofer amp?
What is the advantages of a loc with 12 v power input over the one without any power input?
Can a line output converter like audio control with all the adjustments and 10 V out sound better than a good aftermarket head unit?
What should I do if I want to add 2 amps to my head unit ?
My car doesn't have a stock sub, so I can't use audio control LC6 or LC7.
Can I use a 4 channel LOC or 2 2 channels LOC to power 2 different amps ? 2 2 channels are better to adjust voltage right ?
I'm looking for a wire harness for a 2012 Infiniti QX56. I'm trying to run the RCA from the front of the truck. It's to add the complete system, crossover, amps for mid/high and a bass amp. I have search all over for the wire harness and can't find one. Any ideas on where I can find this in Florida?
Question and it may be a dumb one...
I purchased two amps, one is 4 channel and the other one 2 channel and aftermarket kenwood. Now I'm not a pro but the guys (audio shop) who did al the installation. Installed 2 10's ,9 6's mids, 4 tweeters. Well I noticed they connected everything using high inputs . Which I didn't understand knowing the radio kenwood has 3 outputs RCA's for hi, mid, sub.
I'm I wrong or right that they should of used the RCA inputs ensted?
have you guys tried adding a amp onto a 2017 mazda with a factory amp , im looking for advise and any help
Can you use this if you got a aftermarket radio? I was thinking about buying a SC6 line output signal converter. But I only wanted to use it for having the max input voltage for my sub amp and my 4 channel. I could just plug rca in from aftermarket radio and rca out to the amps?
what if you have only one speaker (sub) on the back. can you connect the two positives and two negatives on LOC (front and rear ) to the single wires from the speaker?
I have a request. Can you make a vedio for a 2000 Lexus ES300 model. I really want to upgrade all my speaker systems. But I want to keep my stock radio cassette player. It would be a great help for me as I am very much interested and like your work. It's so neat. Please make a vedio on this vehicle model.
