Just got my harness yesterday. I must say that the harness was beautifully put together. I thought it was going to be slapped together. I was wrong. Worth every penny
Could you please drop the harness number, or where you purchased. I need to find one online
Super nice setup. Love the plug and play! Might be a customer once I blowout my factory speakers!
Nice work, super clean and professional!
Great job. Hard to find people that dont do a sloppy job!
Thank you for your video. I was wanting to install a system in my 2017 Sierra and wasn't sure how I wanted to do it but and now I know I can do it after watching your video.
I spliced into my harness to get the audio signal and ran 9 strand wire to and from my amp for input and output!. That harness definitely makes it easier for plug and play!
gotta love the Chevy Sierra
technically the accubass on the audiocontrol amplifier and/or the LC7i isnt the same as the epicenter, the accubass is to help with the bass roll off of the radio... meaning as in the bass dropps as the higher you go on the volume to not damage or distort the stock speakers, the epicenter enhances the bass that was rolled off or cut off when the song was produced... but nice install, love your guy's harnesses
Hey LLJ, I got the amp rack plug n play from y’all. I was wondering which bolt y’all recommend using for the custom fuse box bracket y’all made. To everyone wondering if the product is worth it, HELL YES. The build quality is better than I could have expected, and the cost was barely over retail for the equipment included. For a novice, the rack is easily 20-30 hours of labor, if you even had the right tools. LLJ is the real deal
I needed that harness when i did my install on my truck way easier that way and that amp rack very nice. Like your work
That amp rack is fucking sick I need one for my truck
I need one of those loopback harnesses for my 2017.
Hi I’m interested in one of those loopback wiring systems have a 2019 Chevy Silverado high country but the factory Bose I actually text you can you please give me a call back when you get a chance and one more thing do you know where the OnStar module is
Chevy sierra???
That is very nice neat job i must say, good work!. My question you kind of answered but i wanted to be sure, I have 2016 SLT with BOSE system and all i want to do is add kicker sub box and amp. Can this be done with the BOSE system? If so, where do I hook the amp to?
Thank you Greg, and yes you can you would use a bose T-harness R2G and make the connection at the bose amplifier
So if you wanna tinker with your amp settings you gotta go through the trouble of taking the seat out?
I would like a Chevy Sierra SLE srt king ranch 😂
Are you wanting that with the rebel alpine system ?
😂😂😂
What an idiot
🤣🤣🤣
Do you do a Shelby SS Supra CTS model tutorial
Do you sell the entire kit to be plug and play?
Does the OEM loopback harness have the "Remote" wire for the aftermarket amps (Example: AudioControl LC4.800 in the video) or do you have to run that separate from a separate location? Thanks
Where you located that method you just did that’s exactly what I need to get done in my Silverado
so when connecting the AMP to the Stock GM stereo all you need is the loopback harness? Other than that, it is typical power and ground cables and then your connections to the SUB (from amp)
That is correct and an amp or processor like a dsp or lnik6 if your amp does not take high level in .If you do have any questions please reach out to us .happy to help !
Is this harness used so you don't have to cut into the factory wire?
That is correct. This is our old T-harness style our new harnes does the same thing but provides future expansion
@@lljcustomscaraudiofabricat7854 thanks for the reply. I'm trying to add a 4 channel amp for my door speakers and a separate amp for my subs. Is there a harness available to do all this?
@@agugabri14 Awesome, so yes there is and that is our Elite Lookback harness. Depending on the amp you have and if it takes high level input and if you have a factory amplifier or not you may also need a processor. We would be happy to help you with building out your system please send over the part number to the equipment you already own and our techs will give you a few options. Thank you
@@lljcustomscaraudiofabricat7854 so for the door speakers ill be using the Taramps DS 440x4 and for the subs I'll be using the Taramps MD 1800.1, no factory amp. Plus ill be using a LC6i or the LC7i
Hi, someone that such an apology will connect sound to a 2014 high country and when it accelerates, it makes noise to the bass I do not know if you can know what it is that woes so that it does not happen that greeting
Hello if you are getting any back feed to you subs when you accelerate you have ANC and need a bypass
if i have the bose system already in my truck and i want to add a sub, can the bose amplifier take a 400w sub? say a JL audio 12TW3-D4? or will i have to buy a new amp?
Hello Anthony, the factory bose amp does 80 watts so can you run an aftermarket sub yes will it power the sub properly no you would want to add a small amp like a acm1.300 or a Rockford 2.400 that can bridge to 1 channel at 400 watt will probably be 2 ohm so make sure your sub is the same impedance (ohm).
Do you have a harness for people trying to run an amp for the door speakers?
Hello LS, yes we do we are the creators of the OEM loopback harness. This design lets you get signal on one side of the harness and then return it on the other to the factory speakers via the factory wires.
What does the other side of that loop back harness plug into? I have a kicker amp and sub I’m trying to use to just run my sub will that harness work?
@jackdecrow961 if you plan to just add a sub then a T-harness like a R2G or an R2R would be ideal
Did y’all have to run 2 9 wires for the 4 channel.
Absolutely not, 9 wire at the time this was made was only sold in 18Awg and can introduce static into your system. We used an early version of our twisted shock-wire that used 20awg for signal and 16 awg for the return. They now sell a cheap 16awg 9 wire to copy us, but its not twisted and doesn't prevent EMI.
Gotcha, just wasn’t sure on a factory non Bose system. How to get the 9 wire from factory head unit to the Lci, then lci rca to sundown amp. Then amp back up to the radio into harness to door speakers. Slightly confused.
Where did you get the harness wire loop
That goes from original stereo to small amp inputs and from small amp outputs to the original
door speakers?
Hi alejandro, we make them. You can purchase one on our website:
lljcustoms.com/store?olsPage=products%2Foem-loop-harnesses
LLJ Customs Car Audio Fabrication L.L.C I was just looking on site so with this I can bypass buying a processor? Does your harness control signal volume etc
You didn't show what bolt you used to hook up power
You are correct, our apologies. You will wire in at the bolt that comes from the battery connection befor the fuses
So what's the loop back harness I watched to see and you never showed it
You never showed where you hooked up the power cable to near the battery
Where can i get the harness ? I have the bose system for the 2014
Gustavo Rivera did you find the harness?
I never noticed the smokers cough in "Drop It Like It's Hot" until i watched this video.
What do u mean
Do you still need to run wires from ur amps to ur speakers
@@Austin-hl3dn not when you use our loopback harness.
Where you get power for the remot for the amp ?
Tap it from fuse box with a fuse tAp
Hi ! You said you sell the complete system already wired with amps and the rack ? I have a 2014 sierra sle
I have a 2017 Silverado LT . What will be the bolt spacing for the rack ?
Hey man how much was the wiring harness and where did you get it?
Hello, this is our Original Loopback Harness. It is available on our website:
lljcustoms.com/products/2014-2018-gm-gmc-elite-harness-for-vehicles-with-8-or-select-4-screens-without-bose
Need this setup in my truck
hey .would you help with my 2017 GMC SIERRA 1500 . DOORS SPEAKERS UPGRADE WITH AMP BUT. THE PROBLE THE DOOR CHIME INCREASE TOO LOAD >
For that you would use a dsp to limit the Dbs at the frequency the chimes use to lower the intensity of the audio
LLJ, I need this whole set up for my 2014 Silverado crew cab. Could you send me a quote?
I had this done on my truck.. now my air conditioner is acting funny.. if it gets really hot, when i turn the car on none of the AC knobs turn on. then sometimes they do work.. sometimes it blows cold air, and the it blows hot air.. what could be wrong??
If you ise a can bus based product like pac pro those are issues that will happen. Our products NOT mess with any of your factory settings
Is there a link for that green-clipped harness? 7:40

Mine is a 4" tall x 7" wide screen with a green plug but only has 2 wires. Hot and Ground coming out of it. 2014 Chevy Silverado double cab with a Bose system without a woofer. Do you sell a T plug with speaker outputs for this. I assume it would be for back at the amp. I need the speaker outputs to tie in a LOC PRO 7 RCA converter. I want to keep my factory system, just adding a woofer and amp
Can you please send me a quote for that exact set up same making model minus the power wire kit and epicenter. Thank you. I’ll order it as soon as you send it
I got a zero gauge wiring kit and it won't snap underneath the plastic foot panel did you guys run it under the truck or something?
I ordered the same harness, for a 2014 Silverado, I installed an amplifier for the midrange and one for the subwoofers, the problem is that in the midrange the seat belt alarm sounds very loud, how can I fix that problem?
who did you get your harness from ?
Super clean job 🔥 subscribed 🫡
Thank you ! welcome
How much does something like this cost?
Do the warning chimes amplify when install this amplifier
How do I get in touch with your company to get this harness?

Donde puedo comprar todo ese sistema que instalaste los harness y los amplificadores listos para conectar
I am just running a low end system with. Does the harness obsolete having to run the 2 rca cords? I Just wondered if I would need an interface
Where can I buy that loop back harness?
Ballpark figure to get this buy the parts and install? Thanks in advance
install is 250.00 flat fee, the price on this exact kit is 1350.00.
I have a 2014 Chevrolet Silverado 1500 LT Crew cab with an 8 inch factory
radio screen. I'm adding 4 sundown 8 inch 800 watt 2 ohms subwoofers running off of a
810 DM digital processer and the orion 5000 watt class D amplifier.
My truck model does not have the bose amp system.
Which custom harness would you'll recommend for this setup?
Hello , you would want to go with a T-Harness and an LinkDQ. This will let you fix and boost the full bass frequancy range. lljcustoms.com/store/ols/products/2014-2018-gmc-chevy-silverado-sierra-oem-lp7-2-amp-t-harness
How much does something like this cost
Our S.i.K kits at the time where 1200-3000 depending on equipment. now we have a lot of company's who have stolen our designs and try to sell them for 8 and 10 grand a kit with parts you absolutely dont need. definitely do some research before you buy anything from anyone.
Is there any other places you could mount the amps other than the back of the cab,so you didn’t haft to cut anything
Yes sir there is lots of places depending on your set up, how much equipment your installing . You can go under the seat or the center council if you have one u can go under the dash if you doing a micro amp u can install in the top glove box.
Nice install guys looks good are u guys gonna sell that amp rack also
Yes sir we are. We are currently in production and will be shipping in a week.
Nice I’ll make sure to check back with you guys for that
@@MarioTorres-bv3dj sure thing ! You can also visit out sit and send us a message we will add you to the waiting list and email you when they are ready
@@lljcustomscaraudiofabricat7854 I'm interested in the harness that connects to the factory stereo. How much is it?
@@jonisupra the harness prices depends of how you customize it. Send us an email to Sales@lljcustoms.com and we will help you fined the right harness for your vehicle.
Curious what box you used to go under the seat and if it was a single or double. I am trying to locate a good single 12" for my 2016 double cab. Any suggestions?
I like the amp rack. Maybe we can do some business on these.
Hello Raymond, thank you for watching the video. We used a simple ground shaker double 12"'s with some Rockford P3s's. We make a point of showing that expensive doesn't mean its better. Tuning is key . any box you buy make sure your subs will fit and at what frequency that way you know what your looking to get when it comes to your amp and the signal you feed it.
Where did you run the ground?
I have noticed on a lot of UA-cam videos people dont elaborate on their grounding points for this specific generation of trucks smh... grounding is the most important part
How long was the Harness you used? I am doing a similar install in the same type of truck and want to know what I should order.
Im wondering the same thing. Their phone lines are down and they take forever to answer emails.
hello this harness was 20 feet
We apologize Jack Aldridge, we have been work on our new shop. The length on this harness is 20 feet
I’m trying to get a install like that on my truck but I’m scared to let anyone touch my screen deck and mess it up , how much would something like that cost me ?
Have you had any customers complain that the amps get to hot behind the seat?
Hi josh, no sir we have not . It does help that the cab vents are located on the rear well .
Some one needs to show this guy how to clean under the hood that shits dirty hahahah
i need a epicenter if i have a audiocontrol with audio rectifying already !!
i have a 2015 Silverado 1500 and there's only 2 wires coming from the green plug. a red and a black on the far right of the plug. Where would i find the audio wires in this case? Its a rally edition with Bose speakers
Hello, soubds like the vehilces has a Bose amp behind the rear seat. All of the audio will be running through the amp. The wiring behind the screen would just be data.
@@lljcustomscaraudiofabricat7854 Yup, you're right. i did find it.
I need one for a crew cab 15 Silverado with lc7i. What size leads on the lc7i do I need. Don’t even know what that means lol
Leads is the term we use for the overall length of the harness.
Whats the name of the Harness
This is the Elite OEM loopback harness. You can visit our site to build your own. Www.lljcustoms.com
nice install...all i need is that harness. i've done talked to you via email i just have to order it lol
Thank you. Order soon This week and next week you get 10% off all online orders.
What harness is it been looking for it
Im from phoenix where you located at i have the same truck, audio express installed a complete system but did not like it can you help me with some concerns i have or maybe start all over let me know thanks
Dude looks awesome any way possible you can set mine up i have 2017 silverado crew cab lt but set as ltz with leather lmk thanks!
Hi Alex, we have a few different options for this vehicle. Send us an email to support@lljcustoms.com we can help you find the correct set up for your vehicle and project.
Which subs did you use in this application? Also, was the box custom made? I have a 2016 Silverado and I am being told I cannot add anything decent due to the trans hump in the back.
Hello Curtis, i am sure that was followed up by u needing a seat lift and a custom box . No, you dont, and that's the point of this video, we used a single 12 Rockford P3s and a ground shaker box at 380 Watts rms . It is important to tune it correctly, and that is what most shops dont know how to do and why they upsell
@@lljcustomscaraudiofabricat7854 would that work for a dual sub setup?
@LLJ Customs Car Audio Fabrication L.L.C where are you located? If ypu are close enough I am going to pay you a visit.
@@curtiscraft1633 absolutely the make doubt 12inch you could even get a double 13.4 inch jl subs iv had them in our test truck for over 5 years now still sounds great
@@curtiscraft1633 we are located in Phoenix,az . Your are welcome anytime
A Chevy Sierra?
I’m assuming he meant “Sierra/ Silverado” since they’re basically the same exact vehicle.
Where do you land power on the battery? I think I missed that part!
So what your saying is if I have a Bose system I do not have to pull the head unit to add subs?
That is correct the connection is done at the bose amp, thst is on the back wall.
@@lljcustomscaraudiofabricat7854 aswesome thanks.
Price for all that was used here? What size subs were used? Thanks!
I bought your harness for a 2014 Silverado with an LP7-2R. I’m trying to figure out how to tune the system now. There’s gain adjustment in 3 or 4 different places so I don’t know which to adjust and what to set the others to. There’s gain on the LP-7 and the remote gain that connects to it. There’s also gain on my kicker amp and I think there’s a gain setting in the factory radio. Should the all be set to the lowest and adjusted only with the remote gain knob that came with the LP7?
I'm looking in to using that line out put converter. It seems as though that knob is specific to ch 3 the "bass" channel... each gain should be for each channel ..
How much was the whole set up I have a 15 denali I want to do that to.
Hello manny for pricing pleas email us at sales@lljcustoms.com. thank you
Well I was told I need a processor to hook amp to factory radio for door speakers? I have new speakers to put in
Would you happen to know where to get a front speaker mount for 2016 Canyon? The 6x9" OEM mount is about 2.5" thick but the speaker is glued in so I can't reuse that one.
Where are y’all located?
I would like that install on my 2014 GMC Sierra how much and where are you guys located?
Hello Juan, we are based out of Phoenix, AZ. There are a few different options available for this vehicle. You can send us an email to support@lljcustoms.com with your project details, we can help you find the correct set up.
How long is that harness ? @LLJ CUSTOMS
I've been trying to get into contact with llj ....no phone service?
Hello no .the number of calls to shop techs is 150 to 1 its impossible to answer all calls . So we do text,email, social media. This way we get to everyone
Were did you get leaf to put the amplifier
Hola, necesito la base para instalar los amplificadores o de que material es y donde puedo conseguirlo? Mi auto es Chevrolet Silverado 2018 doble cabina extendida
Tienes algún video donde hables español?
I can't use a high power surround sound system because it drained my hearing Aides battery and it will damaged my hearing Aides and my ears .
hello, sorry, how can I get a harness of that for silverado 2020 custom, I'm going to do a similar installation, could you give me the link to buy it or the part number, thanks
Can you use that plug with Bose system to
How much does it cost for you to install this setup?
When you purchase this kits from us locally we just charge a flat $125.00 labor fee. kit takes 2 hours to fully install and tune
Do you sell a kit for these 2017 silverados basically everything you just installed
Hello Andres, yes we do they are out S.I.K Kits
Nice install
Is there any difference in the harness or install if you have the Bose amp in the back if you"re adding two amps or a five channel amp?
Hello, the only difference would be in the amps or amp that you have. Some amps dont use or do need and lc7i depending on there high or speaker level inputs. The bose amp outputs 32v so make sire your equipment is compatible
Hey buddy I install my aftermarket sound system on my Chevrolet 2017 but it's making a lot of noise from the motor how can I fix it
Definitely worth watching !
How many watts is the amp that comes with the loop back harness kit?
How can I get my hands on a setup like this with amp rack? Do I just call the number on the left hand side of the screen, if so who do I ask for?
I ordered that same wiring harness, and the blue one (aux) did not work for me, do you know what the problem would be?
Hello Antonio 👋 when u say AUX and blue what do you mean ? Our harness doesn't have an aux option and the blue wire MAY be the remote turn on depending on your ordered configuration.
