Your videos are the best and very informative. Your knowledge I puck up and in turn help others to understand car audio or direct them to your channel, thanks.
Good video, very informative. The only other step I do is to check the clipping limit before the LOC. I have found most stock systems get to about 2/3's on the volume. I use a 1khz test tone, and an osciliscope (Seeed is my choice of due to ease of use) like can be found on some multimeters. Of course, the DM-RTA does this too.
absolutely perfect video. I wish everyone was like u when teaching us.
Excellent video..
Hi Mark. Great video and very informative!! You are very knowledgeable about car audio. I have started watching your videos and just went I thought I started to understand everything you introduce something else that leaves me scratching my head. I want to add upgraded rear speakers and a sub to my 2022 crew cab Silverado with factory Bose and a factory head unit I’m just upgrading the rear door speakers and adding a 10inch sub. Can you tell me please what I actually need to complete the task. I see all these different components and add ins to the install. What exactly do I need or maybe one amp to handle the whole job. Please help!! So confused. Again your videos are incredibly informative and I enjoy watching because of the technical aspect that you bring to the videos! Great job! But if you can please point me in the correct direction.
Question I have a two-channel loc with base lift . I currently have one input channel hooked from the factory subwoofer . I also want to wire a 4 channel amplifier. Should I use door speakers for input coming out of the stock amplifier in order to feed a full bandwidth of signal? I would imagine I'm not getting the right signal into it in order to have an output correct for a four-channel amp for mids and highs?
Hey 👋,
I have an LC2i connected to my factory amp and am getting a loud hiss from my components. The LC2i is powering a Rockford t1000-4ad any thoughts?
New subcriber here, i have two 6.5" coaxial 2 way speakers 200w 4ohms each and i want to make a box with them adding a 8" subwoofer 4ohms how should i wire'em? All together in parallel or series or separeted from each other? And what gauge of wire should i use? You have great videos
Mark are you going to do the JL Audio Fix 82 video ?
Is contact adhesive the same as contact cement?? Both from DAP
Now do you wire it and tune it please, trying to do it this week
So if I check my RCA cables out of my aftermarket head unit, I should get numbers with my multimeter correct? And what numbers should I be looking for?
So I've I stalled an jvc kwm745 head unit paired with an audison sr5.600. I have looked at the out put of the head unit using an oscilloscope there no cliping at full voltage . Although I have sent the gain to matched the pre out
I was thinking is there any reason why I cannt match it it to the speakers, which are audison rated to 100w rms @ 2ohm. Or set the gain as close to speaker max before oscilloscope shows cliping.
What are ur thoughts
Got one I can't seem to find much info on my factor car radio has a signal ground how do I ground that they don't make a wireing harness for my car so I had to build one the signal ground looks like an antenna wire but a lot smaller
To clear up information on some LOC and DSP they say maximum input of 40Vpp which is only 14.8V on an AC volt meter. Measuring peak to peak (Vpp) is not what a multimeter does.
Have not even got 30 seconds into the video and I know with watching this one it is going to tell me hopefully everything I need to know to add hopefully only needing the LC2i-Pro to do the job of connecting to my 09 Accord EX-L with (premium sound/NO navi). I have a project truck that is my build and wanting to throw just a little bump in the trunk in the new daily driver. Already have another XS D3400 for under the hood that will be sufficient for a DB Euphoria 1200.1 class D amp and a couple entry level Skar SDR-12s I got some time ago for the better halfs vehicle that she did not approve of, LOL!!!! I am hoping this video will tell me on the factory (Premium Sound system) I can use the stock 8" sub wires in the rear deck that I hope will give me the proper voltage to use said LOC and have been told doing so would after all adjustments and tuning made, be able to use factory sub volume control on the deck itself... That would be a perfect scenario of course! If you have ANY WORDS OF WISDOM TO SHARE with a REBORN Enthusiast please by all means let me know. I am a sponge to the industry as things have come a very long way since my earlier very basic knowledge set up years!!! I truly appreciate the way you explain EVERYTHING in a very detailed fashion. Very easy to follow your expertise!!!! Respectfully submitted by an eager to learn more always!!! Thank you for your services!!!!
Can u hook that to a 4 channel amp???
I know this video is old but I have a question about my car. It's a bit long, so is there a Way that I can send it to you directly. Or should I just throw it in the comments?
Question. My cars radio has it's own factory amplifier. When connecting my LC2 for my subs only. Should I use the speakers wires before it reaches the amplifiers (input connector) or the wires afterwards (output connector to speakers) to speakers, or does it matter since the LC2 can regulate the voltage?
Good question I’m waiting for answer for this to
Soooo I may be incorrect, but if you’re gonna hook up a LOC, let’s say for a subwoofer for you, you wanna tap into the speaker wire going to your already existing subwoofer, or the rear speakers or whichever of your factory sound system’s speakers deal with the lower frequencies, since you wanna take those lower frequencies into your aftermarket sub. So yes after the factory amp. As long as it’s going to your factory sub yes. Don’t want to get the tweeter speaker wire because there won’t be any lower frequencies sent to it.
@@ketchumthekid3880^
If you got low frequencies already in the wire your pulling the audio from you can just use a regular passive LOC. But I just ended up getting the LC2i pro anyway cause it just seems like it be cleaner. Iv heard pulling to low of a frequency into the LC2i can cause problems but I haven’t had any mine was hard to figure out cause I had a DVC @ 2ohm x2 factory sub with 4 wires to it. Damn that was a pain.
@ketchumthekid3880 was wondering...I have 2 kicker cvr 10s I wanna run at one ohm so should I gwt a skar loc or should I do a CT or lc2i?
Is there a LOC with 10 outputs?
Hey mark what if I'm not reading output voltage from my lc2i when playing a 40 hertz -5 DB test tone? I was able to read output voltage with the multimeter previously but now I don't get any reading my ground is fine and it still powers up my amplifier and plays bass I just can't accurately tune it?
It's a lc2i pro could the speakers im tapped into possibly be blown? Be the cause of no output voltage I'm sorry I'm new to car audio ☹️
Could I use one of these to boost my line out voltage from a aftermarket head unit that has low RCA pre out voltage?
I did that with the KeyLoc, so yes.
Why is there no video on a LC8i?
Hey, just wanted to ask, I have a fullrange speaker and mid bass in my car. Is it better if i change the fullrange to twitter and add crossover in my system? I notice that my high end sound is quite destroyed kindda sound like. Tq
Hello new to the loc side of things im looking to push about 4k rms between sub,mid,&highs will the lc2i pro give enough power?
Hey Mark I just installed a small system in my 2018 subaru crosstrek.
I have kept the stock system so used an lc7i into a 5 channel amp. I have 2 questions.
#1- when tuning the the sub on the amp side what is the best way to do that in regards to using accubass?
#2- the first thing may solve the 2nd but trying to set the accubass per the instructions I have to bring it to almost all the way on for it to do anything (I do have bad roll off of the bass at volume 30) but when I change the volume after that it's just a random on off switch of the bass (it randomly goes like max bass at different volume levels ... running a test tone or music) any idea why it would do that?
Side note today I turned off auto for channel 3 and used jumper wires. Just incase
Something I don't like about the lc2i is how high my subs play. Before i had my channels connected to a high-low converter and my bass would sound clean, but once i replaced it for the lc2i, my subs play more mid frequency despite how much i play with the lc2i and my amp's frequency filter.
You may want to install a DPS to fix that problem.
Hi Mark.hope i spel your name corectly.i just want to find out the RCA leads.can i run them with the power and remote wires or not.
If you are running them to the amplifier in the same wire channel with the power and remote, you can introduce EMI into the system. I would run the RCAs on the opposite side of the vehicle.
I have always wired everything together.dit not hear enything strange.i wil try that and listen if i hear enything diferent.thanks.wil try it.
@@hendrikhennie6811 Yes, depends on power levels and the quality of the cabling. The good practices mentioned above are ideal. I have always run my cabling separately too. Often I will later change speakers or amps to better or newer quality, while increasing the power levels, and not needing to pull the car apart again to move the wiring.
Thanks.
It's usually best practice to run signal wires on the opposite side of the car as the power wire to reduce the chance of any interference.
That being said if you're only running low-pass signal wires for a subwoofer, you should be okay to run them together.
is it okay to use the LOC from the outputs of the stock amp?
Check your LOC to see how many watts or volts it can handle. Some can handle what a factory amp can send out.
My radio reception isn’t as good since I installed the LC2I pro in my Subaru. Why is that?
Is the antenna plugged in all the way?
@@Yukon_DO_it I’ll check that.
What was the problem ??
Could be RF noise given off from the line out converter , that’s just my theory
What will happen if i connect converter but with wrong speakers polarity ?>
i believe it wont pick up the lows correctly if any
Why wouldn't you by-pass the factory amplifier and feed the line-output converter directly from the head unit?
Because many factory systems use a digital signal from headunit to factory amp.
The line out converter gives your rca signal more voltage so you get a clearer sound out of your aftermarket amplifiers.
Hello I really need help with my system. I need to send you a video. Please let me know how I can contact you. Thanks
My audio system in my 2020 f150 I have two amps 1500 watt one running 4 8s at parallel for 2 olms and a 1800 that was running two kicker lc7 12s at 2 olms my amp is audiopipe. The amp is wired from batter and ground from the bed but keeps blowing subs or killing the voice coils or whateva it’s doing. I tested the amps from the battery like one of your videos stated and it was at 13.54 volts and the volts on the amp was at 13.50. So that’s a 0.04 volt loss which is not much so why are the speakers blowing.
I do hope you get to see this message and help so I can send you the video. I also use a LC2i
