After watching a lot of these videos on LC7i's and LC2i's, I found that some critical information is not being told. Most of these videos instruct everyone to just set the gain on the LC units by looking at the "maximized" lights. The maximized light is just a guide and I believe that the light will always light when DC (clippling) is detected. Most amps have a maximum input sensitivity of 4 - 6 volts on the low inputs. So basically, it's possible that the signal from the LC7i could be too hot for most amps. I got this straight from the audio control website: "The idea is to send the hottest signal possible out of the converter, without distorting the output of the converter, and also not going over the max input gain of the amp. This helps ensure you get the cleanest signal to your amp as possible. For example, if the max input gain sensitivity of your amplifier is 5 volts, we will want to make sure the output of the converter does not go over 5 volts. ***THE MAXIMIZED LIGHT ENSURES YOU DO NOT DISTORT THE OUTPUT OF THE CONVERTER, IT DOES NOT ENSURE THAT YOU WILL NOT DISTORT THE INPUT OF YOUR AMPLIFIER*** The maximized light is a handy tool if you do not have a volt meter handy. It serves as a guide in helping you not distort the input of the amplifier." So basically, these units are great, but we must be careful in adjusting them because if the gains on the LC units are set OVER the maximum input sensitivity of an amp, it would be like using the amp's low input connections as high input connections and that can't be a good thing.

if you start properly, with your amp gains turned all the way down, the maximize light will show clipping before you ever go above the amp's input voltage. unless it's a very well built amp, with extremely clean circuitry , but chances are, if your system contains an amp of this quality, an lc7i would have no place in that system build in the first place.

That just answered the question I posted. Thanks

Thank you Marc! Your teaching is excellent information for my project

Thank you Mark The Jedi Car Audio Master. Always amazing content, lessons, tutorials, & explanation. So gracious & humble.

I'm glad I watched this. Saved a bunch of money. I have a sound processor that only has a single pair of rca inputs, so I can sub everything to the main output and send a full range signal to my processor input

Had an Lc7i in my 2016 Ram 1500 with stock Apline. You definitely need it to bypass the stock amplifier! Did great for me! Now going to use it in my 2018 suburban with Bose system!

Mark is a pro, love that guy, great video

Just got rid of my DSR1 and had the LC7i installed. DSP was so complicated and frustrating. The LOC is set at the start with the amp and that's it. What got me is the sound quality of the LC7i. Blew my mind how clean it sounds and the bass output.

@AudioControl Thanks for the informative posting, helped me make the final purchase decision! I have bought the LC7i along with the ACR-1 Dash Control for a 2015 F-150 with 7 speakers (no sub) that are distributed as follows: 2 front tweeters that share channels with the 2 front door speakers 2 rear speakers and a center dash speaker for a total of 7 speakers. I will be driving two amps with the LC7i: Amp1 is four channels but will drive all six speakers. Channels 1 and 2 will power front speakers and tweeters while channels 3 and 4 will power rear speakers (center dash speaker will have to remain connected to factory source ☹️); Amp2 will power subs. Q1 - Can I run the 4 speaker level inputs from the source unit to LC7i Main Input and Channel 2, Sum channel 2 into the main output, feed AutoMode signal into channel 3 to drive the subs with the mono amp? Q2 -Is there a more suitable set up or recommendation on something that I may be overlooking? Q3 - I will not use GTO, so for the remote power lead, can I connect LC7i at the end of the circuit (after the amps) so that I do not have to fuse the remote out or is there a benefit in placing the LC7i in front of the circuit? Q4 - will I be able to retain fade? Q5 - is there a way to accommodate the center dash speaker to the audio solution? Thank you for your response and for making a great product!

Damn....I NEEDS this!!!!

Well detailed👍. Many guys out there uses this just as a regular hlc, not realising the potential this got 😁

this is great. i’ve had this nightmare problem for 2 years

Really quite helpful. Thx

Thanks 🙏🏿 very informational

Great video explaining the setup for this device. One question: Let's say that your factory Bose amp has separate channels for mids and tweets in the front door, full range speakers in the rear doors and a factory sub. If using the summing feature how do you still retain front to rear fade capability from the head unit?

@AudioControlCar

7 жыл бұрын

With one LOC like the LC7i, to retain fade, you will need to create your sub signal from the front doors and leave the factory sub disconnected. Connect front tweets to input 1, front mids to input 3; sum channel 3 to main. Connect rear to input 2 and leave separate. Now, you will connect the front main output (summed fronts) to the front channel of the after market amp, output 2 to the rear and you can use the front door mids (they usually play into sub woofer range) on channel 3 to the sub amp. Hope that helps.

Hi. Mark!! Just watching your video. Very inspirational and to the point!! Kudos!!! I wanted to learn more about how to upgrade my stereo system, using my stock head unit. I own a 2018 Jeep Compass that comes with the Uconnect sytem like you've mention with a lot of other car features integrates in it. Anyway, what I wish to know is how to upgrade system, but I'm not striving for anything too complex. I'm thinking of replacing all four of my door 6x9 speakers with some JBL 939's and I also have some tweeters up in front but my car also have a 6 inch mid dashboard speakers so it'll be 7 speakers total. I've never done this before so I would need some advice on how to connect all seven speakers with an LC7i unit of something alike and I don't know how many amps I will need. Like I mentioned before, I just want to have a simple but effective upgraded system that sounds decent but I'm not trying to blow my head off with subwoofers or anything alike. What would be your best suggestion to me for the system that I'm intending to build? Thanks in advance for your prompt response.!! 😁👍

Well that explains why the subs I bought sound nicer when they were on display then in my car... Now I know why I loose bass as I turn up my volume. I gotta adjust my threshold than. I never knew that about these new car systems. I have a brand new car . And expected to get the same sound as I heard in the installation shop. And it doesn't sound as great to be honest. But they did install this in my car so now I know how to control my bass and hopefully get a ritcher clean tone.

Great video!

hello a question I have a Jeep Grand Cherokee limited 2018 and I have two amplifier and it has a little noise. it is possible that this piece works thanks

The set up that’s gotten my subs the best signal have not been a factory with line converters. Let me know if there are converters that go over 400 watts.

Thanks for the video, great stuff.I have a question about my current build. I have AudioControl LC7i Black 6-Channel Line Output Converter, 2 after market amps(4ch amp and 2 ch amp(for subs) connecting to a factory Ford radio(i have no choice of using an after-market radio). I'm running 125watt rms to the doors(4ch) so I will use after market speaker cable, not factory internal speaker wire. So with this, im thinking these speaker wires will connect from 4ch amp to the door speakers, which makes sense but my question is where does the 2 sub speaker wire connect from the LC7i to the harness(im using PAC LPHFD31 harness) as the harness will only have the 4 pairs, not 6 which I would need?

Question, I have a Prius with the jbl factory amp wired to components front and back. First which would be the best place to grab signal for lc7i? Also I’m installing new component speakers in font and back so I’m just gonna run new wires off the 4 channel amp and wire the crossover from component speakers to woofer and tweeter right?

My installer connected the first 4 channels on the Lc7i and I still have balance and fade control. I'm assuming that this was done by connecting the front tweeter channels on 1 & 2 and the rear doors channels on 3 & 4? Would this be correct? Can I connect all 6 channel outputs from the HU into the Lc7i, sum them into the first 4 output channels and get full signal on each output?

I have a stock audio 2022 Tacoma and have an Infinity Kappa 6x9 front component speakers with tweeters and crossovers, Infinity Kappa speakers rear, JL Sub and a 5 channel JL amp. Using the LC7i, would I wire my tweeters and front in parallel and use input 1? Rear would go to 2? Sub goes to 3? Then output 1 goes to front amp, 2 goes to rear amp and 3 to sub amp?

So I'm lost on one thing. If im only hooking up a subwoofer. Should I be splicing into all the level inputs? Does it sum the bass output? Or is this overkill for that task? I want to maintain the speakers being powered by the factory amp for the time being, but I want to make sure this thing wont rob power from them.

@AudioControl I just purchased your LC8I to install in my 2014 F350 Platinum with the Sony Sync 2 premium stereo system which has the factory Sony amplifier with subwoofer my question is what speakers should I run into the main high level input the fronts or the tweeters. This is what I've found the...the front tweeters and center channel are together, my front door speakers are bt themselves my rear door speakers are tied together with the rear tweeters and the sub is by itself, what would be the best way to set up my LC8I. Note I'm adding 2 amps 1 for mids and highs and 1 for sub.

Pl give a list of all Audio Control products to upgrade existing sound system in Jeep Compass. Thanks

Installed my LC7i yesterday, and noticed that i was having some crazy noise in my system. I mean CRAZY. After trouble shooting (checking grounds, etc) I found that my LC7i is apparently wired exactly backwards. The "main" outout is actually my sub, and my "sub" is actually my front stage. Also, I have to keep all 3 outputs from the LC7i just off the bare minimum setting. Anything more, and it sends rediculous noise into my amp. After finally figuring this out, I have the gain on my amp at or slightly above "normal" gain setting. I thought I was supposed to be able to keep it low...?

Can someone answer if im using the summed feature. my inputs are from my tweters and my door speakers , do I only connect to the main output ? or will the subwoofer output also work? reason im asking is I understand how the summing works and a fullrange signal comes out of the main but do I then split this main to my amplifiers or can i use the second and third outputs also in this summed mode ?

I obviously have 4 speakers, two in each door. Do I just need to hook up two doors to the midrange inputs?

Can I wire the LC7i before the stock amp for my bmw speakers and out of the channels main and 2 back to the stock amp and the 3rd channel of the LC7i to the aftermarket amp for the aftermarket subs? Appreciate all your videos, really helpful for my home projects. Thank you!

I would like to know why on stock stereos some install techs use the front speakers to power the sub signal in the LC7i, I thought this wouldn't matter since both front and rear are full range in a basic stock radio.

When a factory amp is present, you will interface with the signals coming OUT of the OEM amplifier. You would interrupt the signals coming out of the factory amp and send them into the LC7i. Then, the other side of the wiring left will be the leads that connect to the vehicle's speakers. These wires will need to be connected to the output side of your new aftermarket amplifier.

It is usually best to connect direct to the battery. Most installers run a heavy gauge wire from battery for the amp into a distribution block. From the block connect the LC2i and the amp.

You would probably want your LC7i channel 1 output running to a 4 channel amp, which would drive your front and rear speakers. It would also power your tweeters, because you would run your tweeters in parallel with your front door speakers using a crossover. I know this is late but it might help somebody.
