Introduction to AudioControl's LC7i part 3 "how to do 2 channel input and 3 channel output"

[@x58evo2puma7]

I have ordered one of these the main speakers wires from the unit if I’m correct do the wires from the main unit do they goin in the speakers main speakers for front and for the rear they go in the next one in the lc7i this will be my first time to install one of these bad boys

[@tkotx]

So what if I have front and rear tweeters in the factory system as well but no amp and no subwoofer but I'm going to be adding both. Basically I have 2018 Honda Accord sport and I'm going to be installing JL component speakers in the front and rear powered by a 4 channel amp and then installing a 8" JL powered Microsub. When I go to feed the signal to the LC7I do I pull front for channel 1 and rear for channel 2 or do I pull tweeters for channel 1 and mids for channel 2?

[@FunkJammer1901]

I have the same vehicle and want to do almost the same. Did you end up figuring it out?

[@rigolopez9639]

Just curious, do the (connected to main channel) green lights above output level controls not come on when running the unit this way? I have the lc7i also but I don’t think they come on?

[@LITSGARAGE]

Hey guys! Ok so i have a 2012 Ram with a factory touch screen with Bluetooth/GPS/DVD/USB etc. i need to convert my speaker wires to rca’s obviously and i have a 2k sub amp on 4 12’s in a blow through... now its time to add and upgrade my mids and highs!! So I wanna add an amp for those now so what would be my best unit and way of setting it up ?

[@lucianoking5]

Ok I’m looking to run mids and highs in my front and back doors as well as two subs would I need this LC7i to run three amps? 🤔 what would you recommend

[@fw1367]

Hey. Do i need this loc if i just Want factory stereo and loc and amp 4ch to front and rear speaker. No sub going to be installed ,,,, Or ist bass roll of anyway? Do it work set gain and stereo on 70%and not turn up vol higher in future.

[@Jpatel17]

I have a 2011 Nissan Maxima with Nav/Bose. What would be the best way setup the lc7i. Doing Component set in the froni, coax in back doors and sub.

[@NvTwist]

Question: why did the RTA show roll off on the very low freq when switched between the rear out put and the sub output. The RTA showed and very flat signal on the front and rear out pits but the sub just dropped off. I noticed when you turned up AccuBASS the lowest leveles came up but it was now level output was way to high in the upper sub freq range. Is there a way to keep the sub freq flat like it was in the front and rear channels and keep the sub channel just as flat? Hope I explained it well.

[@gun_shine_st8137]

Great videos Thank you, I have a small problem. After installing my LC7i I have no mids or highs, well i do but they are very, very low. I only have a 2 channel amp available at this time feeding my speakers after the LC7i. Will this cause the issue i am having? I am on my way to purchase an 4 channel after I post.

[@bigque1988]

Ok I’m lost I watched all 3 videos and I’m still confused I have a lc6i not 7i but I’m sure u run them the same however I have a 2012 vw Touareg tdi lux and it does not have a factory amp/sub how do I run lc6i to add a 4 channel amp and a sub amp any info would help thank you guys and great videos

[@ryche2882]

Love your videos guys. You make it seem so simple. Great work. I just purchased a LC7i for my vehicle. I have a new 2018 F150 without the Sony system. I am going to add my own amps, 1 for the speakers, one for the Sub. Question, to get my signal from the head I need to cut the factory wiring, which I would rather not do. I have been looking for a harness, and reverse harness to use instead but I am not able to locate them. Do you sell, or do you know of where I could purchase the harnesses?you guys rock!

[@rigolopez9639]

are you guys gettin the signal from the door speakers or head unit ?

[@kaliabehrav]

Hello sir, i have subaru legacy with Harman Karam amp and subwoofer. I wants to add 5 channel amp. Where is the best location to install it for lc7.1) After amplifier output? 2) amplifier has different channel outputs high mid and low. Which configuration should i follow ? No. 3 video ?

[@emiliomauleon3846]

I have a 06 Chrysler Pacifica with Factory Infinity system. My radio only has left and right front speakers wires going into a amp and the output has front, rear, front center and a sub . I am confused on how it works and how to make a true front, front center, rear and a sub. any better ways to do this?

[@Maarrtinn]

Can you please explain?? @ 2:30 why is front and rear on the first channel and how are they wired ?? Doubled in there ??

[@samuelaiken2570]

Hey man I have a 2015 Toyota Highlander without JBL. I added a 4 channel amp for my door speakers and front tweeter and also another amp for my 2 12” skar subs. I installed the LC7I but the sound isn’t that great from my speakers, and also when I unplug the lc7i the sound still comes out of my speakers but I don’t have a factory amp.. what could be the issue? Thank you.

[@zoomgh0st]

You're supposed to get signal for the lc7i from factory wiring such as front and back. If you have an oem amp, you get signal from output side of oem amp. Additionally you can get front signal from front doors for main in 1 of lc7i, rear signal in from rear door speakers to channel 2 in of lc7i, then out to front, rear and channel 3 out of lc7i to aftermarket sub amp.

[@tony5089]

Guys I really need help I want to set up the Lc7i in my 2016 Tacoma I have the base system with the two upper tweeters, and the 4 door speakers. I upgraded to 4 focal co-axial’s in the doors and my focal amp(I’m going to add a sub later on). How should I wire this up? Do I need to use the summing options? I’m fine with losing my fader options I just want the cleanest sound to each of the speakers since I know I’m not adding any tweeters up in the dash. Thank You

[@hadbl12]

When you set the LC7 on initial setup, how often do you have to make adjustments to it

[@mrcc13]

Hi guys I am writing from Australia. Thanks for all yours post I have been learning a lot. I know you don't have this model of car in USA, but should be the same thing as in other cars. I have a Toyota Fortuner 2016 and want to use the oem or factory radio but I want to install a 5 channel jl audio HD900/5. Which LOC you recommend to use ( LC7i ) or maybe other brand ? How can I get the signal for the sub woofer If I only have 4channles front speaker and rear speakers. You have already showed me how to do it. But I saw the configuration that you did in Introduction to AudioControl's LC7i part 2 "how to do 2 way summing plus subwoofer". My question will be, Can I do some kind of the same configuration like separate the signal High, Medium and low? I am going to put in the front and rear Alpine SPR-60C 6.5" TYPE R Component Speakers. Thanks for your help. Cheers!

[@FiveStarCarStereoInc]

It sounds like you want to do a 3 way active crossover system. To do that you really only need a left and right output from the radio. You could use the Lc2i and go into a 5 channel amp that has the crossover ability to do that. Phoenix Gold makes the Ti2 1600.5 that works great for that type of install.

[@mrcc13]

Hi guys thanks for your answer. Sorry I am not a professional installer, I just need to understand a few things. I know you are very busy but if you could explain me a little bit more in detail I will be grateful for ever. The stereo of the cars comes with four pair of wires (8 wires): Two pair’s front (Right and Left side) and two pairs Rear (Right and Left side). I was watching the picture LC2i and it comes with two speakers input. How Can I connect everything? If you could provide me a diagram it will be easier to understand ([e-mail]). Also, the output exit is one in theory because the other one it will go directly to the sub woofer line rca in the amplifier. It means that only left one RCA output exit. I need to buy a simple RCA with double RCA at the end? To go the outputs of the LC2i to the inputs in the amplifier front (L-R) and Rear (L-R)? Thanks for all your help and sorry for the troubles!!!

[@dEeM0nEy916]

ey guys trying to decide between audio control lcq1 and kicker front row, your thoughts would be greatly appreciated! wanting to keep factory radio on my '17 Ram 1500 w/ 8.4 Uconnect non-amplified..thanks guys!

[@chriscormack8522]

So can you get 6 channel output from just a left and right signal input?

[@dmain37]

I get it, I get it.... I don't get it... :-) Hello, and thank you for your time and efforts! 2006 Nissan Titan Crew Cab. Factory head with 6 disc changer, NON-Fosgate - no Sub. Replacing in dash tweeters, front door and rear door speakers with Infinity REF series. I plan on mounting LC7i under driver seat, as well as an amp with sub channel. How am I getting signal to the LC7i? Am I to keep original factory speaker connections? Am I replacing wires, or tapping into whats already run? Am I running new wires from amp to speakers? I see the block diagram: Radio Head Unit, to LC7i, to AMP, to Speakers. Then I hear youn say all signals into one? Then I see you connect your visual meter to each of three outputs. No one has had a video on a full install that I can find to help my feeble mind wrap around this stuff. Anything you can throw my way to help me understand would be greatly appreciated. Thanks Guys! David

[@FiveStarCarStereoInc]

So for you I would go by the BHA 7550 and the BHO 7550 reverse harness. This way you can make a nice "t" harness going to your radio. You will run the front inputs into main on the LC. Run the rears into input 2 on the LC. This will automatically create a sub output for input 3. Run the 3 RCAs out to your amps. Run your amps output the speakers input on the "t " harness. Basically you will make it a plug and play.

[@dmain37]

Hi Dean, OK, I think I do get it now... Pull the factory plugs from the back of the factory head unit. Take the Metra 70-7550 Wiring Harness now going to be plugged into the head unit, and make really long extensions to all wires to run from head unit to under the seat and attach to the LC7i. Plug short RCA cables from LC7i into amp for front and rear, run power out from LC7i to amp, and run longer RCA to sub under rear seat (does a sub only have one connection, then?). Add really long extensions to Metra Reverse Wiring Harness 71-7550, connected to output of amp back to head unit and connect its plug to the original head unit plug pulled at first step. Does all that sound right? When I searched for BHA and BHO, Metra always came up, so direct me to correct if needed. Thanks! (my head hurts a little.... :-) )

[@FiveStarCarStereoInc]

Yeah you got it. The Metra harness will do the trick, they are the same. This way no cut harness.

[@budaalamalamusic]

Thanks now I have another problem I can't find I fuse on my Lexus GS 2015 for a remote do know how to get it done and sorry for so many questions

[@FiveStarCarStereoInc]

The LC will make a remote turn on for you, It is the feature call GTO - great turn on. Just connect power and ground run the remote out to the amp. When the radio speakers turn on in input one the LC will do magic.

[@heribertofigueroa1895]

I have 6 speakers 8' inch and 2 horn driver 1.75inch each side doors do I need 2 audio control ?

[@gerardogomez4125]

When i run my signal wire from the factory stereo to the lc7i do i run it the opposite side from the power wire from the amp or can i run it on the same side ?

[@sidg8169]

Does the LC7I automatically generate a subwoofer Signal ?

[@FiveStarCarStereoInc]

+Sid G it take the signal off whatever is feeding the rear speakers.

[@ManuelMoctezuma]

i have a 2014 kia optima ex, basic oem stereo, no amps no subs. 6 speakers total 2(3.5) in the dash, 2(6.75) in front and rear doors. i want to keep the factory hu and replace all the speakers. i have already replaced the dash speaker's with polk audio db3.5's and installed the resistors and they sound decent. so my question is first do you know what the front and dash speaker config is for this model? is there a crossover for the two are they run in series from the HU? second assuming they are and i only have 4 channels out from the HU will this lc7i be what i need to run an amp to all 4 door speakers and keep the dash speaker's on the HU or can i run the 4 channels from the HU and then seperate the dash speakers from the lc7i? i dont want to install a sub just yet so i want to run the 2 dash speakers 2 front door speakers and 2 rear door speakers, would the config be HU-LC7i-AMP-SPEAKERS?

[@FiveStarCarStereoInc]

If the Kia is a base model stereo, then the dash and front speakers should be in parallel. The LC7i would be the right choice for this install. I would get a 4 channel amp and power everything from the amp ( dash and all speakers). Yes it goes radio- LC- amp- speaker. I hope this helps some.

[@daylaun]

Before I go out and get one my only question is... Does the acubass work on all outputs or just the sub output.. Thanks in advance

[@satanas666reyna3]

Samuel Matthew just the sub channel

[@k5_kiaupgrades622]

I get how this LC7i works but installing it in my car I’m confused on how to add it on. I have a 2013 Kia Optima sxL that comes with the infinity audio. And the front doors have mid range and tweeters and rear doors are hi pass how do I go about getting all speakers to play on this audio control I heard about suming but how do I go about doing it.

[@Maarrtinn]

The jumpers that are in the lc7i. You have to remove the cover to switch them. if you really need to do that

[@joem7331]

Great videos!!! I have a 2015 accord w/navi where do i put my lc8i inputs? After headunit? Or after oem amp??

[@FiveStarCarStereoInc]

Joe M it would go after the amp. In that car you may be able to go before the amp by just adding so RCAs. I believe the radio has a variable line output into the amp. Check out this video for more information. kzbin.info/www/bejne/bIvaYWeDi8eBqa8

[@joem7331]

Ok thanks, either way its ok to go after amp than?

[@FiveStarCarStereoInc]

Joe M yes that is were it goes.

[@opalocka7430]

Five Star Car Stereo hey I have a 2013 avalone with the Jbl set up and it suck.the head unit only have bass, mids and trouble.I replace all my factory speakers with 2way and 3ways but you hear nothing out of the tweeters only mids.what must I don't.I wish their was a way to hack the system

[@TommyBlazeHD]

Five Star Car Stereo Wrong! It goes BEFORE the amp!

[@donhommy4251]

I will have the same setup 2 input 2 out speakers and 1 sub but I want to add a crossover how and where install

[@jdoggy314]

i know..i figure that out but i got aftermarket speakers and so i should turn down the acute bass all the way down and turn up stereo until i hear it's bass drop which is kind of hard..and turn acute bass..

[@FiveStarCarStereoInc]

Try this- Turn the AccuBASSTM Level control fully down, rotate the threshold control fully clockwise to lock in the bass equalization. Now you can turn up the AccuBASSTM Level control for the amount of bass you want.

[@jasongodinez8061]

I have a 2013 Dodge Charger, with the small touch screen/climate control. I want to keep it but run two amps. One to run 4 channel to doors and rear deck and one monoblock for a single 12 inch sub (front dash speakers to be powered by deck alone). Would this LC7i be the product I need to do this?

[@FiveStarCarStereoInc]

Yes it will also check out there amps the lc7i is built in. kzbin.info/www/bejne/mnarppuCfaisr6s

[@savionsmith7418]

Five Star Car Stereo I have the same car...2013 charger. I am pretty sure that the rear speakers have more bass than the front channels do, this being said, should I sum the front and rear together then use my amplifiers hpf, or could that much summing hurt the lc7i or make it cut out?

[@mendezeddie1322]

Does this benefit aftermarket radios?

[@hvcool]

how about a 01 740 bmw which has 4 rear deck , front and rear door factory speakers - i believe total of 10 plus speakers - how do u connect this to that or we need a different LOC unit

[@FiveStarCarStereoInc]

hvcool is it the I drive system? If so behind the radio has four outputs you can use.

[@xSlider2009x]

What would be the best configuration for a 2013 F150 with factory head? I want to keep my factory head. My truck has pillar tweeters and door speakers. I believe the crossover is in the factory head. I want to replace all factory speakers and power them with a separate amp. Also, want to add another amp and sub. Does the accubass only work on sub bass or can it restore bass frequencies in the mid bass/door speakers?

[@FiveStarCarStereoInc]

First question would be dose it have the Sony system? Is there a factory amp under the dash kind of by the steering column? Is there a factory subwoofer?

[@xSlider2009x]

+Five Star Car Stereo No it does not have the Sony system that I'm aware of. No subwoofer. It has the sync system, no nav, no touchscreen. 2013 F150 STX supercab. BTW, great videos on the AudioControl gear.

[@thenapierfamily]

Did you ever get one for your f150? I have one coming for my 2011 f150 with just the basic radio like you got. Did it make a great improvement?

[@FiveStarCarStereoInc]

Devin Nguyen if your radio has just front and rear output and you are going to front, rear, and sub. Do nothing, that is factory default. That you for watching

[@DeezyTheDude]

I'm wanting to run 3 amps in an 2013 audi a7 prestige that has the bose system. I'm going to run 2 polk tweeters and a pair of kicker 6 in speakers from a 125.2 amp... another pair of kick 6 inch and a pair of kicker 6x9s with a zx 400.4 amps.... and a pair of JL 10w3v3 's with a dx 1000.1 amp..... Would this product be best for setting that up then?

[@FiveStarCarStereoInc]

It may, it depends on how may channels you have to sum together to get the outputs you want. You need to know that first before you get the summing device.

[@DeezyTheDude]

I dont think I need to sum any, the stock system has "high, mid, sub"

[@FiveStarCarStereoInc]

+Landau Lang are you going to an active system?

[@jdoggy314]

hey i notice that when I play it at 1/2 then turn it up to 3/4 of volume the bass just from low to real high like a delay. ..any advice

[@FiveStarCarStereoInc]

Check the accubass setting. It sound like it is turning on at the wrong time.

[@spongeturd33]

I have a 2011 Nissan Juke with s factory sub and I wanna run a sundown x15 but I have a factory radio would the lc6i allow me to do this ??

If you are just doing a sub all you would need is the lc2i.

[@nolamoons5759]

Five Star Car Stereo I read everyone's comments but I'm confused. The lc7i says it has may speaker level input of 400 w rms...so I can't run 2 X 12s at 400 rms each on a 1 ohm impedance?????

will do..thanks

Does the lc7 take the place of a equalizer,or is it better and possible to add an equalizer?

[@Islandsilvia]

Hey guys I have a question and I will be as detailed as possible. I am interested in purchasing either an lc6i or possibly an lc6i (unsure just yet). I have a 2009 be Jetta without a premium sound system. The plan is to replace the main 4 door speakers with NVX VSP65 both front and rear with a pioneer GM-D8604 to power them and for bass I am using a Rockford P300-10. Would I need to leave the automode on, run the front into ch1, rears into ch2 and would ch3 provide me with a clean output to run my P300-10 cleanly? If not would there be another way to set up the jumpers internally to have ch3 as dedicated bass output? Additionally would you recommend the lc6i or lc7i based on the above.

[@kenmasters1403]

Can u use the lc7i wth a after market stereo

[@zoomgh0st]

You defeat the purpose of it

[@budaalamalamusic]

Can I run the power from my power amp cable need a fuse ?

[@FiveStarCarStereoInc]

Yes you can connect it to the amp for power. If the unit is going to be a far distance from the amp and the wire is a risk of getting pinched use a fuse.

[@adameccleston554]

How did you connect Phonic PAA3 to LC7i?

[@FiveStarCarStereoInc]

Adam Eccleston we made a XLR to RCA cable. It will take speaker level or line level in

[@adameccleston554]

I'd like to make a XLR to RCA cable, what do I need to make it? Your videos are on point!

[@LRSS2455]

I think you should make a whole video on the PAA3 or PAA3X. How to tune a system with it, how to identify distortion, and how to make those wonderful cables you have made.

[@Mmadad30]

sorry should have been more clear on what I'm doing I'm installing the LC7i and also 2 12in apline type r with with seperate amps running the subs could I use one of the other inputs to run the second amp and sub or will I have to split the channel 3 signal

[@FiveStarCarStereoInc]

Mmadad30 most sub amps have an input and an output for a second amp. What amps did you get.

[@Mmadad30]

Five Star Car Stereo audio pipe 1500 watt mono D

[@FiveStarCarStereoInc]

Mmadad30 yes that sub amp has an in and out

[@jdoggy314]

p.s how do you tune it

[@FiveStarCarStereoInc]

+jdoggy314 here is our steps for tuning. First check the Phase on all the speakers to make sure there are none backwards. you can get an app on you phone or a phase checker on Amazon for $8.00(search-Black-Speaker-Polarity-Tester)Next- turn all the level and gain to there lowest settings, make sure Bass and Treble are 0, and unplug the RCA's to the amps. Then get a pink noise generator ( on your phone or disc)and play it in the radio with the volume 3/4 of the way up. If you have access to a SMD-DD1 you can use that for a more accurate volume level. Next turn up the output levels on the LC7i until the Maximized light starts to flicker, it is best for it to stay off altogether. Now turn the volume down, remove the pink noise and plug in the highs amp rca only. Play some music you know well, set the Xover on the amp to your liking. Check sound at all levels if you feel you need more Gain you can add some but I would not go past a 1/4. Turn it back down and plug in the sub amp, repeat previous steps. Make sure the blend is good with small adjustment to gain or levels( Maximized light will come on with music, it is OK). Play multiple types of music for best performance. Enjoy.
