Removed my seat this evening. ‘22 TB. There is a module to move over and you can mount an amp rack. You have about 18” x 6” or 7” for an amp. Probably will have to shave some foam, but it will work. It’s a pain in the ass. Thanks for the video.
Thank you,hope this helps someone.
There are 4 10 mm bolts under the seats that bolt to the wall. Remove head rests and the plastic tubes from seats. then there is 3 locks behind seat at top that release back seats. Don’t have to remove bench
the cloth straps are marking the locations of the pull up latches you need to access to remove the back seat /plus 4 10 mm screws under the seat and the seat comes out/use a rebar wire tie twister tool to pull up the latches/takes about 10 minutes
I don't have an amp. And I don't want a system. But I have a silverado, and you taught me something. Thank you so much. 100k more miles, and I'm sure I'll be using what I learned to fix it. Thanks
To remove the back of the rear seat you have to remove the headrests and then unplug the female end pieces that hold the headrest male ends down into the seat. Those hold the back of seat clipped into the back wall. Hope that helps. Thanks for the video.
Just 2020 silverado, after cutting box from under rear seat put 2 12" port box zstat rms 600. Probably near 500w now. Amazing sound. Thinking of getting new door speakers to increase clarity, but God is good.
What amp would you suggest for boss amps?
Boss sucks.
Back seat comes out by removing the headrests and pole sockets and four 10mm bolts at the bottom.
Yep. And enough room back there to mount amps or sound processors.
@@C5turbo 100%.. .hell, even their amp is back there lol
They prob. called their local GM dealership and those lazy ____’s don’t know difference in their ass from a hole in the ground. Or these guys don’t know to much about that period. I think they just rushed a video out because there are not many aftermarket audio install videos featuring these trucks
@@TrustedBanterSociety thats exacly what happened and even gm customer service was no help but thankes to a viewer they found a video of an upholstery shop that figured it out. We just didn't want to brake anything
@@lljcustomscaraudiofabricat7854 where can I find the loop harness and what is it called
Thanks a lot for this video. Lots of helpful install information!
There is tons of room behind the back seat. I have 2 Tru Technology amps and 4 DynAudio crossovers back there.
Correct unfortunately at the time of the video.No information on how to remove the seat was available. We reached out to gm but it was a week later they replied with the information and customer was from out of town. By then others had made how to remove it videos so we left it at that.but yes a good amount of space is available
I recently purchased my harness for my 2020 Trail Boss ran it to a LC2i pro and man it sounds perfect.
Would of liked a vinyl sticker for my window though.😉
Hi i have a 2020 custom and like to do sound system can u show me the harness u orden...and the wait u connected? Also have to run new wires for the door speakers?
Thanks for the video. I ordered the harness and amp mount for my 2020 2500hd.
Very nice and detailed. Thanks brother.
4 bolts and 3 latches and back seat rest comes out. Plenty of room for an amp
So the blank spot on the dash where the brake controller normal goes i 3d printer adapters to remove that blank and add a brake controller. Could make it so you can add the gain nob for the amp.
Great info and a cool piece. I unfortunately have the pleasure of fitting 2 Voce 5ch amp in a Denali this week. :0
Great video, thanks a los for your advice, appreciate your big help
They took my seat off in a 2019 GMC Sierra same seat doesn’t open down they took the seat off and mounted it and ran my wires through the back panel there’s tons of space in there where you had the zip tie came out perfect
Hello Blitzy, yes we found out after the video was posted that the seat could be removed by pulling out the head rest holders. Thank you
Nice vid and harness work!
Back seat comes out by remove the headrests and sockets and four 10mm bolts at the bottom.
Very nice. Thanks for the helpful install info.
Very clean looking kit. Love the loop harness. Do you have any photos of the mounting plate while in its place?
Hello earnie, yes sir we do on our Instagram page @lljcustoms.
Did you have to cut away the carpet underneath the acrylic?
I have a 2019 Silverado RST with boss sound system, and I would like to just add an amplifier with two 10" subwoofers, can you tell me which harness I need and what is the price, thank you
Hello, if you have the bose system you would want to use our Bose amp T-harness. We have a video on the location of the amp for a 2018 model. The only difference is how the seat is removed
I swear my Sierra is one weird Monday morning build. Passenger side bundle under the hood does NOT have that pass through for extra wires.
Uhhh.. theirs a factory amp behind the back seat in my 21.. head rests out.. tubes out.. yank 3 clips. 4 bolts in bottom. Its out
Hello Ryan, yes that would be the bose amp. This was the first 2019 silverado video and at the time that information was not avaliable. We found out 2 days after we recorded how to do it. The customer was here from California and we didn't want to brake something.
I have a 2020 Chevy 1500 double cab (non Bose). I want to add amplifiers for subs and speakers in the doors. What harness do I need to get from you?
Hello, you woukd want a loopback harness with a dsp/amp or with a link4/linkDQ this will give you the 6 rca options you need to add any amplifier configuration you want
Do you know what wires are the speaker wires to a 2022 Silverado custom
Got my amp behind the backseat mounted on back wall of the cab. Not sure why you can’t remove the seat
Hi Chase, yes ater the video was finished we found out that night how the rear seat could be removed.
Should make a video on how to remove the back seat thanks
Where did you tap the amp signal on wire from on the truck? I have a 2020 LT Trailboss and I am not sure where to tap power from for the signal wire. My truck does have a factory amp, unlike the one shown in the video, so I am thinking I can tap that power wire going to the factory amp, but I am not sure which wire that is, unless there is somewhere else to get that power signal from. Thanks for any advice.
Is there only 4 channel speaker level outputs from the factory radio that go into the LC61200? I’m just curious on how you wired in the tweets with that set up and also curious on how the factory has them wired in the factory amp
Hello Chris,
in this situation the lc6.1200 is the processor the dash tweeters are wired parallel to the front doors . if you use your own crossover, say you are using a 3 or 4 way setup you would run the additional wires separately or over the loop with the component configuration.
Very informative !! Im not gonna try any of this, but it's good to know this video exists..hehe
Great video, I seen in your comments on the 3" leg room for premium, I didn't realize that, I have a 2019 RST Z71 w/Bose, everything is behind my back seat, the inverter, bose amp, and I added 2 kicker 600watt amps, to run my 2 12" kicker comp speakers in sealed box, wish you guy's were close by me here in Dayton Ohio, I am having some issues with mine, I have been told I need to replace the bose system, I just want better highs, and I don't think the subs are hooked up correctly, thinking about going with a 1000watt Q-kicker amp, it has the digital processor, I am also getting my son's 2020 Malibu RS fully upgraded as well, I just bought a focal set up, I am going to check out your website. Thanks
Love it great job brother
Hi Luis - Will this work on a 2020 trail boss? No Bose system, I want to replace all my door speakers and install a sub. Ideally a would like an amp for each. What product would you recommend to do just that?
I have a Question regarding the System and Battery install. Connecting the Zero Gauge wire directly to the battery, is there any parasitic power draw after the vehicle is shut off?
not if you pull the remote from a source that turns off when the CPU does so that no draw happens after the car goes to sleep.
Keep them coming thank you
Is it possible to rise a little the back seat at all?
Any way to find out which wires are left & right front & back without testing it out?
So the kit will pretty much include everything but enclosure, sub, and door speakers correct? What the price point? Also noticed this truck was not Bose equipped, I have Bose, if I wanted to run my factory door speakers for now and upgrade later would the loop-back harness still work? Does the acrylic have to come with the TrailBoss etching??? Can it be changed or left blank.
That is correct the kit will come with everything needed if you have a bose system the connection will be done behind the seat ..vehicles with the premium package lose the 3 inch leg room so the bose amp and power inverter can go behind the seat. The amp rack can be blank or if you would like a custom rack that is something we can arrange .email us are sales@lljcustoms.com if you have any questions on the customization of the kit. Thank you
Thanks for video, I will be calling soon, I have trail boss with Bose need the harness to add boom boom and door speakers!
What size is that lug connection for ground wire?
Amy recommendations in the Dallas area?
I have a 2019 Trail Boss non-Bose 7" screen and have visited you website but I am unsure of what harness I need to hook up my powered subwoofer. Plus I have tried to contact you numerous times, email and text with no response. Can you recommend the right harness?
WHAT DO YOU WANT TO INSTALL?
I have the Bose system. Will the install be different? I have kicker mono and 12” Kenwood enclosure I took out my 09 Sil
Any reason why some trucks are aqua and tan and others gray and black connectors?
I just ordered 1, there is no issue running power next to the signal wires?
What harness would I need for my 2021 rst Silverado with the Bose and 8 inch screen
What would be the best harness if I’m just adding a 500 watt amp and 2 8” subs under back seat?
Hi, I am trying to install myself an amplifier for a subwoofer and I have a silverado 2020 but y don’t know where to connect the wires that control the on/off of the amplifier. I will appreciate if you can give me a heads up. Thank you
Do I necessarily need the amp for the mapa infinity speakers!???
Hello alex absolutely not you can use any amp you want. The kits we offer have matched specs. However you can use any combo of speakers and amps so long as they work together when it comes to playable frequency and power
What fuse did you run the signal wire off of? I have a 2020 Silverado 2500HD and im still trying to figure that out lol
I am in Los Angeles looking for a shop i can trust to do some great work on my 2020rst. Any info would be greatly appreciated. Great videos very helpful
Did you find one? I'll be going to SoundDiego.. in SD
I have a 2017 Chevy premiere with Bose system I have the subs, amp, and wiring kit. What else do I need to install my system?
Ok I have 2 questions for my 21 rst with the Bose what harness would I need to add a couple subwoofers and is there a harness to loop back into factory harness if I want to add a 4 channel amp and change the door and dash speakers
Like to run amp for speaker's doors and amp for subs. This harness works on my silverado 2020 custom. Non bose.? Or wich one need to get, also have to run wires for the sepakers doors?
If you plan to upgrade the doors and add a sub all you need is a loopback harness with a 5 channel amplifier. The loop will give you signal and the return back to the speaker location. So no new wire runs are needed
@@lljcustomscaraudiofabricat7854 how can I order one!!
?
@viktorfrankenstein1240 on our website at the end of next month we will start taking order again for loops
@lljcustomscaraudiofabricat7854 thanks like to see the price, and can I git the link?
If a guy didn't want a sub would the stock system be ok to drive those infinity speakers?
Do you recommend doing a big three on these trucks ?
The benefits are minimal unless you are also planning on upgrading your alternator.
What is the harness # I need I have a 2019 trail boss with the aqua and gray plug on mine like yours
Hello, Here is the link to the Aqua/ Tan harness lljcustoms.com/products/2019-2022-gm-gmc-elite-t-harness-without-bose?_pos=3&_psq=aqua&_ss=e&_v=1.0
Where did you get your remote wire power?
were did you get remote from?
What size terminal do you need for the ground?
Nice 👌 amp
What size Torx bit did you need for the grounding bolt?
Which one are the color to connect?
Hey boss,
I have 2019 rst i need the harness
The truck has bass roll-off??
I have the epicenter amp i just need the harness
How much??
No bass knob? How do you control the subwoofer level without an aftermarket head unit? As far as I know, there is NOT a subwoofer level in the sound settings of the factory 6 or 8 inch touch screen from GM on these trucks. There is Bass, Mid, & Treb; however, tuning the bass setting on the GM head unit, tunes the bass levels on the door speakers and if you were to have a sub it would raise that with the door speakers. We all know that can make for terrible sound. Idk about you, but I don’t want to have to go fiddle with the settings on the back of the amp every time I wish to adjust my sub’s levels…?
Hello Bryce, this customer decided to add the bass remot later we did run the wire. Any quality amp will come with a remote or atleast the connector port. The gain remote is always the last connected anyway so not to throw off the gain set on the amplifier
Have you done a High Country? Curious if it's same as this trail boss...
Did you notice any motor ground noise in the system because of running the amp power wire along with the speaker wires?
NO, we use balanced wire in out harness (twisted pair) so any electric interference is blocked out. To this day we have never had that issue. This is another reason why we tell people to stay away from speed wire.
@@lljcustomscaraudiofabricat7854 Great! Can you give me the link to it? I am going to be adding two amps (one for the doors and a second for the subs) into my 2020 RST Silverado. So I would welcome any help. And thank you for the video!
@@johnphillips2582 Thank you for watching. Here is the link to this Harness system once you know the connector color make sure to select the correct harness.lljcustoms.com/collections/elite-harness-series/EHS
How does the acrylic amp base mount?
Hi do yuo have for sale t harnes for the new 2020 gnc sierra
DO I HAVE TO INSTALL AN AFTERMARKET CD PLAYER IN MY 2019 CHEVY SILVERADO FOR THE JACK PLUGS FROM THE AMPLIFIER TO WORK
No...you can use the high inputs for the amp and tap into the door speakers.
How did u break through the fire wall lugs?
How do I know if I need a high to low adapter? Its been 15 yrs since Ive
installed a system. I just bought a rockford fosgate powered ported
shallow fire sub 300rms for my 19 silverado. Do i need the high to low adapter? or just a
standard amp wiring kit?
Hello Bradbssargdons, your amp would determine if you need an LOC or not look at the input of your amp if it takes less then 5v the use an lp7-2. 5-10v get a link2 or lc2i pro 0-40v you can go in high/speaker level
very easy to remove the seatback and plenty of room behind for an amp.
Hi and thank you for your videos. Where can I mount my skar 2000?It’s kind of long and I don’t know where the best place is to put it. Somebody told me the backseat will come off after you remove the head rest, is that true? Thank you for your help.
Hello, yes that is correct. It was later discovered that by removing the head rest and the plastic guide for headrest can be removed and the seat with it
Ware did you buy your subwoofer box
what size speaker for the front 6x9? 6.5 in back?
So how do you get into the accessory port through the firewall? Did you go through the existing wiring or create another path?
we go in next to the main harness on the passenger side.
I just got my loop harness from you guys! Please tell me how you got the original harness detached. I feel like I’m going to break the original khaki and teal ones. HELP🥲
Hello David, there is a lock tab on the OEM plug that need to be pulled back then press down amd wiggle the connector out
@@lljcustomscaraudiofabricat7854 this is going to be a terribly worded question & please feel free to tell me you don’t understand. Does the lock tab get pushed toward the wires or away from the wires to unlock?
@@123killermiller123 its will slide back away from the radio unit towards the wires
@@lljcustomscaraudiofabricat7854 still can’t get it. I suck. I can’t find what the lock tap is and nothing will budge. I got a good shot of the OEM plug is there anyway I can contact you guys to send you a picture of what one seeing and you can tell me exactly where the lock is?
What type of speaker box did y'all end up going with
we did a single Rockford p3s in a sealed box . you can check out the video on of facebook page
Where did you connect for the remote wire?
Rafael Fuerte did you find out how to connect the rem wire?
What's the price on the harness
I have a 2020 RST, I would like to purchase a harness.
Where did you get your ground wire connector? I am trying to use that same bolt to ground amp. The amp kit doesn’t come one big enough to fit under.
Hello Obediah , would you tell me what you mean by amp kit ? Like the power kit or one of our S.I.K kits ?
@@lljcustomscaraudiofabricat7854 I was talking the wire lug you were using. My wire kit didn’t come with one big enough to go around that bolt but I found one. Thanks
@@obediahanderson788 yes ours are 5/8 most wire kits are 1/2 or smaller
Can you use a line out converter in a 2020 gmc sierra elevation also what can I tap into?
Yup eBay has them
yo i got a 2021 silverado i will be using my own equipment i just want the wire harness
You can buy just the wires from our site so you can use any equipment you already own. we support that heavily
I’ve looked everywhere for a plug and play adapter for a kicker key amp. Do you guys make one? If not do you have any info on what color the speaker wires are?
Yes we do make one, it is our OEM Loop Back Harness. Here is a link: lljcustoms.com/store?olsPage=products%2Foem-loop-harnesses
Any noise issues running signal wires next to the power wire in the channel there?
hello J Cook, no not at all our wire uses a 3mm thick jacket and we then twist the wires inside the harness
Do you still sell this kit?
Is this kit still available?
I have an LT trailboss with the bose sound system. My question is can I just do a sub instead of full speaker install?
Hello, yes of course you would just use our bose amp T-harness with a link2.
@@lljcustomscaraudiofabricat7854 whats the difference between the link 2 and an lc2i
will this work on a rst?
yes it will just need to know the color of the connectors.
Can you guys make a video similar to this one on the 2020 Chevrolet 2500 HD ?
hello I just need t harness for a 2019 gmc with bose speakers with black and grey connectors (just wires)
What length did you use for the Loop Back Harness?
Hello, we used a 20 foot loop and that left 3 or so feet extra
Too bad we couldn't sample the final results
Dont worry there will be a park 2 including the finished sub woofer set up.🎸🔊
where is this located ive bn trying to put subs in mine but no one wants to do it
we are in Glendale AZ but we ship world wide
How much does it run for every
This kit was 1200 shipped
Where is the rem wire on this truck?
Adam Smelser did you find the rem wire?
You’re running the zero gauge power right next to the audio signal harness??? Wtf
Rookie mistake, what are you thinking?
No thats not it .. see we use and introduced the twisted speaker wire to car audio. Just how 5 star copies it. We actually know what we are doing. And twist our wire so that we create an EMI shield that prevents any and all electrical interfaces from entering your audio signal. Something speed wire doesn't do.
@@lljcustomscaraudiofabricat7854 5 star says never run your power and audio signal in parallel, but they can intersect.
I’ve never heard that you can run a twisted wire along a power wire and it’s okay.
Forever me if I’m ignorant, I’m just a regular Joe and not a professional…. But I’ve heard this repeated from every car audio guru video and car audio shows.
@tylerwitte714 yea 5 star is not what we call a great example they are paid to push products by pac and metra, and just like Pac and metra, 5 star copies our designs and methods. If you go back in video you can see that we have always twisted our wire to prevent EMI in the audio wire its the same method used in ethernet wire. The twist lets the wire create an electromagnet shield that prevents interface. Look up EMI twisted wire and you will see a few people explain how it works. 5star also used expandable pvc and we use ABS or HDPE they also ground there amps together and thats not ideal in case of a surge. They dont do a lot right, but to people who dont know better, it seems right. They also stole our under hood fuse mount idea. They have taken the quality that we built and try to copy it in order to validate overcharging given that they use speed wire and not 100% copper. They push the lc2i when the LinkDQ is far superior. They give some useful tips but are far from expert's.
Guess you didn’t spend enough time trying to remove back seat. What dealership would tell you that you can’t remove back seat loo
speak spanish ??
