LC7i Active Line Out Converter Discussion and Review

[@stickyleg6541]

This guy deserves way more subscribers. Some of most clear, and in depth car audio videos on KZbin.

[@WarriorsPhoto]

Agreed! I am learning a lot about sound system installation. 😊

[@logantic]

This was the most understandably clear explanation on the LC7i and its use and how to setup it up thank you so much 🤙🏽

[@bensiok]

Both of your LC7i videos are FIRE man!!! You explain it better than basically everyone. So easy it's simple.

[@TheTecatemn]

A lot of great information, that is truly appreciated. It's thanks to people like you, who take their time on the Tube, that help so many of us out here. Kudos! 👍

[@FreelancerGamer]

Finally someone explained the subwoofer channel Thanks!!!!! What do you think LC7i is enough or should I spend more money to buy the DM-608 with more options and software to configure it?

[@nicholasbaker2904]

Best description of this product I've ever seen. Answered so many questions. Thank you

[@jackleonard2088]

I was on the biz for years and you did a very good job of explaining a complex piece of equipment. Enjoy your tunes!!

[@honeybadgerwrx]

Thank you for making this content. It's helping me a ton with understanding how and why I would want to put this into 1 of my Subaru's. Although I so feel somewhat overwhelmed still with the process and how to do it correctly to get the peak efficiency of everything, I appreciate this video nonetheless. Thanks and I really hope you love your new STI as much as I love my 13 WRX and 07 STI.

[@LTSRIDE24]

I've seen more videos on the LC7 than I'd like to admit & this is by far the best & only one that truly explains the inner workings well. Thank you for that!! I purchased this recently & an still struggling on how to / where to splice into my factory amp. I'm trying to avoid running new wire back to my 4 door speakers & utilize the wiring that's already there.

[@akqjtn]

I mean, what exactly are you trying to accomplish?

[@LTSRIDE24]

@@akqjtn trying to figure out where I splice into the wiring at for my signal going into the LC8...the speaker wires going into the factory amplifier or coming out? I have a '14 Edge Sport w/ the Sony 12 speaker system and I plan to utilize the factory amp for most of the stock speakers and the front doors, front tweeters, & rear door speakers I plan to bypass the factory amp and run through my aftermarket amp. I'd like to avoid having to run new wiring and utilize the wiring that is already in place, but I'm a little confused on where to splice in and it's not the easiest to identify which wires are going in and which are coming out, with sooooo many wires! My end game goal is to utilize the LC7 to run an aftermarket amp to power 6 speakers that I've already upgraded (front doors, front tweeters, and rear doors - all aftermarket Infinity speakers) & also connect to the LC7, my Orion 2500 mono amp that is currently powering (2) SA-12 v2's, which at the moment I'm using a basic Kicker LOC.

[@akqjtn]

OK, the beauty about the LC7i is that the channels can handle up to 400watts in so you could easily plug in post Amp if that's easiest. That said, best practice would be to use the signal before the Amp because that signal is cleaner since it's not already amplified.

[@akqjtn]

Try the forums to find a diagram of your sound system

[@LTSRIDE24]

@@akqjtn so, I spliced into my front door speakers for my main input, rear doors for my channel 2, & spliced into my factory subwoofer wiring for my 3rd channel. If I'm understanding what you said, correctly, I think I have my settings correct. I switched my auto mode to OFF (DOWN), I left summing OFF (DOWN), & the other jumper DOWN also. Can you confirm that this is correct please?

[@thedjrush]

This product definitely made it possible to upgrade my entire basic sound on my 2016 Camaro by adding a 4 channel Amp and a Mono channel for my subwoofers 🔊

[@ProtomanBlues]

I just did the same on my 6 gen a life saver for sure!

[@ricric-po4pq]

Did you have the mylink Bose factory system??

[@thisistheslam]

CAF is a life saver for audio installation advice. I've learned so much from that channel. Just bought the LC7i for use in my 2016 F-150 with the 8" Sync 3 7-speaker system (not Sony). Just got it hooked up and am ready to blast some tunes with a clean signal using my OEM head unit. It's a spendy piece of equipment and I wish it had an EQ controller for the same price but maybe I'm asking too much? I don't really want to add in so many signal chain units because space isn't unlimited but maybe I'll end up doing that down the line because I'm sure I'll eventually get annoyed with my limited control with a simplistic 3-band EQ.

[@choochoochar]

Did you end up wiring the rear speakers to the main input or channel 2? About to do this install in a 2018 f-150. Thanks in advance

[@sansantos75]

1000 % I have an lc7i & still haven't installed it.. this episode has shed major light & now I'll be installing it.. thnx bro👍👍👍👍🙌🙌🙌🙌🙌🙌🙌🤦‍♂️

[@jorgel673]

absolutely great video i am completely new to LOCs and im getting ready to revamp my audio in my silverado and this video alone has helped so much.

[@Withlovefrominterent]

For anybody with a newer car, you should look into whether your stock radio requires a certain resistance level from the speakers to work correctly. After I installed the LC7i in my 2022 Outback Wilderness, I wasn't getting any sound from the rear speakers and the radio volume control was sluggish and not actually controlling the volume anymore. It turns out, the LC7i does not place an electrical load on the stereo, so the car thought that the rear speakers had been disconnected and stopped working properly as a result. To address this, you can look into the AC LGD made by Audio Control that attaches very easily to the LC7i, or if that won't work (some cars require a very specific resistance), you can just order and install a couple of resistors to the signal leads right before they go into the LC7i to get the stereo to behave correctly again.

[@akqjtn]

Thank you very much for taking the time to share that. Take care!

[@4545Tiny]

Had the same issue with my car when I added an amp to my 6x9s.

[@Dying_Breed.300]

Can’t u just use a matrix with the lc7i

[@NOSHISHIPANTEEZ808]

You need 47 ohm 5 watt resistors connected to the front left and right channels will make your system scream. It should work

[@jamesfair9751]

Thank you for this video!! You answered all the questions I have for this unit's operation!! This confirmed that I made the right decision in buying this!!

[@alexron2023]

I just ordered my LC7i and can't wait to connect it -thanks for your info

[@AlbertBrotherProductions]

Only question I have is will this bypass the issue of a factory amp? Just spent 10+ hours in a sound shop and my Jeep gladiator is causing havoc with trying to have 2 amps. I’m looking for a solution and I am tempted to pull the trigger on this to see if it works

[@christianwood3072]

[@josea.garcia3994]

Great video and very informative,but with all the features and capabilities of that LC7i the install can easily get some one confused if your not very familiar with it!!! I'm new to your channel now as a subscriber so I will continue to watch your videos and hopefully learn a lot more of all the new car audio equipment that's out in the market like the LC7i and other products from AUDIO CONTROL and from other brands that you may present in your videos!!! 👍👍👍

[@baruwrxyz9772]

Great vid as always! I have a question about your previous video (long long ago but somewhat related to this vid) about the Alpine KTP-445U. I know you ran that to your Rockford Fosgate amp in your WRX - but would I be able to run the KTP445U as the only amp I have? If so, I believe I'd have to tap it to the battery directly to power it, am I correct?

[@SirBrass]

I'm wondering where you accessed all the headunit outputs, and also if you made sure the aftermarket tweeter impedence matched what the telematics unit was expecting to see.

[@bckyazzup1b611]

[@nickvidz2458]

Best explanation yet!

[@bradleysproul5478]

Best video on the LC7I on basically how to install. What is the Alpine unit you have in the video? I was considering the Rockford fosgate 6 channel AMP in correspondence to the LC7I. Do you think that would be okay or would you use a separate in line amp for the speakers

[@bradleysproul5478]

Boost & Shutter that’s what I figured, since it is grabbing the signal from that second channel for the sub. Do you think it would still be alright to run dual subs, or just one

[@M.GVARGAS]

Bradley Sproul to answer your last question. You can run duo duals depending on how much watts the subs are and how much watts are on your amp. For example I have 2 12 inch subs that are 1800 watts total so I got a 2500 watt amp. Also your door speakers for example if they are power range: 5-55 watts RMS (110 watts peak power) than you wold need the 2500 watt amp to hang with that amount of power. Sometimes it depends on the brand of amp you got too.

[@bradleysproul5478]

Hey boss, good work. Where did you get/buy the diagram for your factory stereo, to find out which channels are being attenuated and which are full range without processing by the head unit? I'm in the process of upgrading my 2020 Jeep Grand Cherokee stereo and that is the one thing I need to know before biting the bullet, spending over $1000 just to then get a crappy signal to my system is annoying.

Thanks very helpful I just bought the lc7i

[@GrownManGames]

I hope you are still active on here, you have the best explaination video on this ever. Question. How would i tap into my factory amp (in my case mark levinson amp from 08 lexus gs 350) so that it can connect to the audio control unit?

[@Withlovefrominterent]

Regarding your front speakers and tweeters that you mentioned at 1:19, how do you combine the signal for each on this unit when only using the first two sets of inputs (assuming the third set will be left empty in order to duplicate the rear speaker channel for the sub)? Edit: nevermind, I watched it again and you mentioned they are already wired in parallel. I wonder if the same is true in my car for the front door speakers and tweeters (factory)... most likely as they are technically only one channel.

[@hectorortega9131]

Hello what I would like know is if you connected this Pack Unit before or after the original equipment amplifier, on the input side coming out of the stereo or on the output side coming out of the factory amplifier?

[@nasoccerplayer311]

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?

[@hadbl12]

Once this is setup how up properly.... how often do you have to tweak it? Is it wise to mount it inside the dash or is it something that should be mounted out in the open, which would allow easy access to continued fine tuning??????

[@luisaceves2728]

Great video with enough information to do it yourself, definitely accurate video!

[@DogFamBamNededog]

Thanks for the info! Your video answered my LC7i questions. With regards to your front tweeters and mids did you take each of +/- wires from each driver (left & right, respectively) and combined them, then run a single wire (+/-) to the LC7i? Thanks in advance for your feedback.

[@rum3459]

Love the video and how you explain how the LC7I work my question is I’m putting 2amps in my 2021 jeep wrangler will this work for me because I want to hook everything up to my factory radio

[@ClaudBol]

Right now I currently have a cheap regular high to low converter hooked up to a 4 channel amp and a subwoofer amp with the audio control Epic Center

[@B15SDMDESIGNS]

Is there any lag between the changes to the volume knob and the signal output?

[@floridahockeydadschmidt8348]

very helpful, thank you. For a 2017 Toyota 4 Runner with a non JBL stereo, would you recommend using the stock speaker wire? I've upgraded the dash and front door speakers. Thanks in advance!

[@DJMEDIC671]

Very informative but I’m still confused on if the stock car came with 5 speakers (4 doors a center speaker and 2 Pilar tweets) will the lc7i work? Will I still have access to fade and balance from the stock control of the deck?

[@Narcolepsykid]

So you cut your speakerwires at your oem unit?

I have a 2020 WRX and have done a lot of work using your videos as guides, so thank you! I currently have a 5 channel amp powering my speakers and sub. The amp came with high level inputs so I didn't NEED a line output converter, but I've been very disappointed with the sound. I feel like I'm not getting the best out of the amp and speakers, so I think I'm going to get get a LC7i. This should really improve the sound, right?

[@danbernal7419]

Great diy video no bs direct and to the point . Liked the video very much

[@xiphiperformance9086]

Great Video - If I have a Factory Amp (Honda Civic Si 2013) It is my understanding the LC7i would accept the wires for all 5 channels (F, R, SW) from the Factory Amp, then the LC7i would convert the signal form High to Low, the I can run the signal to Amp 1 (Front and Rear) and Amp 2 for Subwoofer. Am I understanding that correctly? Thank you for the hard work on the videos.

[@dbwiskus]

Basically same setup I have. Not having much luck with setup tho. On my amp, Ch 2, Ch 4 have 38 volts on the speaker outputs with the gain at 0. But Ch 1, and Ch 3 have 17 volts which I have adjusted for gain setting. Amp keeps overheating. Very frustrating

[@ClaudBol]

Yes

[@newmoney8128]

He really made me feel like the people I paid to do my install did not do it right because using the LC7i for what he indicated and how it should properly be done I do not feel that the audio company I went to went in depth to making sure I got the quality sound I deserve for the money I spent on all of my equipment

Hey my man I need some help!! I watched your videos many times and still a little uncertain of what I need to do. I have a 2020 Wrx that I installed Alpines S series on the doors with kicker tweeters. Still have factory head unit that I am trying to work with. To make sound quality better your saying I need a LC and amplifier? Do I have to cut into factory wires to ensure STARLINK still works? How did you do that with the telematics? Sorry for being so long, I want to learn how to do this, electricity has always been my weakness smh.

[@iNDOmOTO1]

What if I have 3 way speakers? Can I still bridge them together and still use it as 4 channel? And use the sub line ? I have 6(tweeter, mid, woofer) in the front and 4 (tweeter, woofer) back doors

[@alexandrupara4574]

If you have a setup like that in the car, mostly you have a premium audio system by factory's default. Honestly even if you upgrade to a active line output plus a DSP and amplifier, you won't "hear" a big difference (not for the money you invested, at least). But at the end of the day, if you still want to do it, keep in mind that 3 way speaker setup from the door, is most likely a single Ch with a build in crossover.

[@erichernandez4983]

Is the signal coming from the front speakers out of the head unit stronger than the rear like you said in the video? But wouldnt that be sending more high and mids to the subwoofer when it should be getting lows? Asking because I installed it that way and feel like the bass isnt hitting the lows but rather the highs and mids.. Should i just switch the rears to the channel 2 and the fronts to the main that way the sub gets more lows?

[@julesbruchez-outperformtra2020]

Does anyone know that if your stock radio has a subwoofer is it equalized also? Meaning this 1. Does it have till off like the front stage speakers 2. Does it have a subsonic filter not allowing it to play low frequencies such as 30-40hz? Regardless of this I am also running the LC7i in my Lexus 350 with multiple amps. Will the LC7i work on the sun channel connected directly to the subwoofer output from the Lexus OEM amplifier with a FULL single? I swear my bass sounds muddy as I turn it up LOUDER. I have a Kicker 1200.1 on two sealed 10” Infinity Subs. If there is a crossover issues coming from the stock radio from the amp to the LC7i can I correct it and turn it back to a full single?
