One of the best how tos I've seen. Getting ready for an install this weekend amd doing it with my 14 yo. Great video to explain the process better than I could.
This is so helpful! I've four sundown 8s and subdown 2000 watt amp, lc2i and harness for bose sitting in mybgarage for 1.5yrs because people wanted to charge me outrageously to install.
Straight to the point, no BS.
I just installed a slim subwoofer in my '21 1500 AT4 Duramax and it was a hassle to run the power cable. Kudos for the engineers who figured out how to come up with most complicated battery removal process in the history of mankind. Not sure if it because mine is diesel, I didn't have space to squeeze my hand in order to pass the battery cable through the firewall without battery removal. Now after all the work, I am returning the slim sub since it is very weak. You can only feel it if you are in the back seat. Going to try a 6.5" bass tube since I don't want to lose the storage bin and also don't want to pay $700 for the Kicker OEM solution. An 8" bazooka would be too big to fit the storage bin.
and probably sound better. i have always used two 6.5" or one 8" bazookas in all of my trucks. i'm thinking about putting them in my 2022. i have been too lazy to tackle this. Another thing i would like to do is to tap into both front channels instead of one. I need to find the wiring colors for my non bose truck.
Very informative video if not the best, very detailed and in depth for newer gm trucks, I am about to install a sub for my dads 2020 silverado. This defintely clears up any questions and concerns I had for this specific make and model. Thank you very much Leaman!
You ran a speaker wire along the passeger channel to tap your audio line for your LC2, but isnt that signal already in the back right on the amp harness?
Finally an AWESOME VIDEO on how to install a sound system THANK YOU!!! What gauge is the power wire 4? Would 0 Gauge fit thru the slot in the fire wall well?
Any answer to this ?
I ran 0 gauge today. I was having trouble, it might sound silly but I put a little Vaseline on it and fed it in until I could reach it from inside the cab.
For the 2019 gmc sierra 1500 non bose the wires you need on the passenger side are blue and white braided together
I have 2 blue and white braided but one has a darker shaded blue?
Know the color for 2021 Silverado trailboss custom
So could you hook up a 4 channel if needed be threw that harness that you tapped into??
Waiting to see a video of you operating the subs. Hate to tap in to those wires and get no bass signal through the LC2i pro.
Wdym?
Would be nice if you made a video on how to wire the amp :/ New to all of this but I got most of it done , ran the power Thru firewall and have the fuse on the battery cover like you did but Im not sure how to tap in to the radio speaker cable ( can’t find the correct colors for my 2020 Silverado custom ) tried both passenger and driver side harness and I’m trying to figure out wiring the amp itself I got the Power and ground cable in but now I’m trying to figure out the rest.
Another installer said in his video that the yellow and yellow/black wires were a sub channel. Wonder if he got it wrong.
Thanks for the tip 👍
For that 1500 watt amp did you have to upgrade your electrical? Big 3? Battery? Or alternator? And voltage lose?
Did you have to bypass the anc module?
So did I hear you say you used the 12v power from the amp to the LC2 instead of tapping in to a fuse?
which wires is for the low signal?
Can you run 0gauge sire through that channel where you fed the power wire through?
What size t taps did you use?
You have the Bose system. You could have pulled the speaker input right off the factory amp on the back wall behind the seat. Would have had to pull and use less wires. Clean install 🤙🏼
Is it the same wiring for Chevy Silverado 2021
Thank you.
Would you happen to know why my amp won’t shut off? I have it wired exactly the same as the video but the LC2 just stays powered on. There is a hum coming from the subs as well. I unhook the power and plug it back in and it’s off and then a close my door and the amp powers up again.
Could 0/1 gauge fit the factory grommet
I got a 2024 silverado with bose pre installed and for the rubber grommet near battery terminal it doesn't have the accessory plug for me to feed through for positive. Any ideas?
What size gauge are your speaker wires??
Where did you get the box from ??
What size bolt you use for the ground?
Did you disconnect the factory sub
How much wire length from battery to rear?
if youre tapping into a speaker wire then aren't you tapping a signal that has already been amplified? It seems like you're amplifying an already amplified signal. Or does the factory amp only amplify the factory sub and not the doors?
I have a 2019 Chevy Silverado 1500 LD.
I looked up the wiring online and want to make sure I have my wire taps going into the right spot. It says yellow and black for the front right speaker. This is a non Bose system.
Did you ever have a backfeed on the speakers? have a minor backfeed ( thump ) every 5-10 minutes even if the truck is off
That’s normally a bad ground on the amp or a rca converter
I need to see how to connect those wires into the radio
Where did you get the sub box from?
How did you deal with the RVC?
Looking forward to listen how the bass sounds, like I said previously, I have a 2021 Tahoe High Country and would like to install a similar system? Where exactly would I find the color of the Bose speaker wires?
It’s gonna be the two braided wires inside the harness one plain and one with the black stripe I don’t have a Bose so mine is on the driver side and they are lime green and lime green with the black stripe
Won’t work
I have this set up on my 2022 Trailboss and need to know if there is something I can add to remove the bass from the front speakers and only come from the kicker base?
Turn the bass down on your head unit. If your subs turn down to the point where your not happy get a bigger amplifier
So with the LC2 you didn’t have to run a remote wire? Also what amp is that? It fit perfect on the back of that box
Correct. The amp is a ct sounds mono 1500w
@@leamangriffin very nice… How well is it pushing those subs
Kicker makes a cheaper version called the kisloc2 it has the auto sensing for the remote wire but you don’t have all the eq adjustments but it’s super small and will fit inside the channel too if you don’t want to have something as big as the lc2
I have this install the exact same way. But I don't like the sound. I can't figure out gain is all set. No clipping on any indicator. But the speakers sound like they raddle when being pushed. Everything is tight. Super frustrating on my 2024 trail boss
How many watts are you running bro? Stock alternator?
Anyone know what a 2023 Chevy Silverado no Bose wires would be? Or how to find it out? Any help would be much appreciated.
Bet them shorts are louder than them subs
so instead of running 4 wires from left positive and negative, and right positive and negative. you just ran from the right and jumped it at the LOC?
Yes. The only thing you lose is if bass sigbals are in the left channel only.. but that is rare for songs to direct low end sounds like that.
What size bolt did u use to replace the bolt used on the ground wire .
Did you end up doing it ,?
hey, great video.. I just installed a kicker hideaway powered sub in my 22 silverado. tapped into these two wires (yellow/black) but I got no sound from sub. Am I missing something?
If you have Bose, those are the wrong wire colors
@432stinger it is bose yes. everything i seen online said to use those
You’re not getting sound bc that’s the wrong signal wires. Door speakers on a Bose system doesn’t play the low bass frequencies like the factory sub plays therefore you need to tap into facorty sub wires which is blue/grey and green/black on Bose amp
@432stinger you were 100% correct. Thanks a lot. I removed side panel to center console, located blue/green wires to factory sub for signal, and perfect! worked like a charm. Also, Kickers instructions are wrong and their tech support did not know the answers.
If I don’t have the Bose system can I still tap into those same wired for the RCA’s or where can I plug them in at?
NOPE, THE HIGH AND LOW FOR NON BOSE ARE THE GREEN AND GREEN WITH BLACK STRIPE TWISTED TOGETHER ON THE DRIVERS SIDE JUST UNDER THE ROCKER COVER BEHIND THE FRONT SEAT BOLT AREA. THE LOOM IS IN THE MIDDLE WHERE IT GOES UNDER THE SEAT.
How are you going to have a stereo signal if you only tapped one sides speaker wire? You’re only going to amplify a mono signal and miss everything that would have been coming out of the other channel?
Do u think my 1500 skars monoblock push my svr 8 d4 skars
Great video. What size was the nut for the ground?
came to ask the same
@@deloreshaze I ended up using the bolt that holds the backseat down on the driver's side because I was in a rush. Later on I may go back to that area and I'll report the size
@@CaptPayback just went to AutoZone. M10X1.5X11
@@deloreshaze appreciate it! Thanks!
Did I see something running like a little mice or cockroaches? By the pillar
could really use some help. got the exact same truck and the Bose using an LC2i pro and the GTO will not turn either the amp or the lc2i on. I tapped into the yellow/yellow and black wires and I have speaker signal. I verified by switching the lc2i to "audio" turn on but it only stays on once and then shuts off and won't turn back on. Wondering what the deal is. don't want to have to run a remote wire.
Bad ground?
@@edboy2784 I actually got the "audio" turn on setting to work. I was only using the right side of the speaker inputs and not both. Either the lc2i needs to get audio signal from both, or it needs it from the left side. So it works not. But the GTO will not work what so ever. Others have said they had to use a remote wire from the fuse panel.
@@edboy2784 I'm an idiot. So the left side is what is primarily used for the turn on signal. GTO does work and I have to use the left side of speaker inputs, not right side.
@@TeeCamp10 I’m trying to figure this out also..lol. Currently running wires to the driver side loom for the input converter!
@@edboy2784 many videos like this one that show how to do it. I went on the passenger side and connected to the front door speaker. I will eventually try and hook it to the oem bose sub wires because i think the door speaker has a crossover in the lower frequencies. Its just a PITA to get to the sub wire.
What’s the size of that grounding bolt. Need to go buy it too.
Did you ever figure it out ??
I did but don’t remember what it was. Just bought multi pack and found one that fit lol
@@ImGootz did you figure it out
@@SpookyMontero I did bro but I forgot 😂
Did you disable the active noise cancelling?
Ever get an answer from this?
i have a '21 gmc sierra elevation WITHOUT Bose and im having trouble finding the right wires to tap into for the rca if anyone could help id be thankful
Did you find out? I have 2020 no Bose
👍👍🥳❗
Doesn’t work on a 21 trailboss with Bose. The Bose is wired differently
Sound Storm EV4.400
MY 4 CHANNEL AMP LOOKS LIKE THIS IN THE REAR 🧐🥴

HOW TO SET UP 4 6.5" SPEAKERS BRO WITH LOUDEST PERFORMANCE. CAN YOU MAKE ME A DIAGRAM USING (RED ♥️/BLACK 🖤) SYMBOLS, INSTEAD OF (+/-). No subwoofers
Is the lc2 needed?
I was going to ask the same question. I was curious if tapping into the front speakers means that you will hear treble or voices through the subs more. Maybe it’s a silly question for me. But good question from you
I usually use a loc7
@@Lerchcon i tapped the front speakers for aftermarket mids and it amplified the door chime. At the same time i got a bad high pitch like an alternator pitch that i cant stil get rid of. I changed the ground to another place and still cannot get rid of it. So i just unhooked the mid speakers and just tapped the sub to the rear speakers. The rear speakers have less volume from the front ones that i know on the 2019 and up.
Tried both, lc2i, and regular LOC the other day on a 2020. There's an audible difference in sound quality. Definitely worth getting the lc2i
You just need a loc converter. Doesn’t have to be this one. There are some cheap on Amazon that work just fine if not better then this.
IF YOU HAVE A BOSE SYSTEM, DO NOT CATCH THE YELLOW/YELLOW-BLACK. Those are the wrong signal wires. You need to catch factory sub signal which is blue/gray + and then green/black is negative(at Bose amp behind rear seat on back wall). I am certified installed and someone sent me this video after not getting the right sound
The OEM kicker sub GM offers has directions that state to tap into the yellow & yellow/black wires. I’m adding a subwoofer soon. Which wires do I do……?
@@joshuaplace9095 if you have Bose system it’ll be the blue/grey & green/black wires at the amp on back wall, if not the wires you said are fine to tap into
@@432stinger3 thank you for the input. Helps out a lot. Thinking about getting a T harness to plug directly into the bose amp. Would I be covered and okay to pursue this route without problems. I don’t believe the 23s have ANC
@432stinger3 what if you DONT have the Bose. Which wires would they be?? Thanks
@432stinger3 I have a 21 silverado non-bose. I was thinking about doing the Fix86 from Jlaudio to give me a clean signal into the vxi amps. Will that work or should I go a different route? Thanks
Does anyone know what the colors the wires are for a 2021 Silverado with out Bose
Did you ever figure it out?
Pretty sure it’s Green & Green/Black on the driver side. I have a 2020, should be the same.
Green/black & Blue/grey.
**at the bose amp at least. Top black plug. You'll have to cut the tape on the harness off to be able to work with it better.
Anyone with a smidgen of car audio knowledge knows this guy is completely wrong, you don’t run your power and signal wires down the same side of truck, passenger side traditionally used for signal/speaker wires and driver side used for power wires, to maximize noise interference, there a grommet under the steering column that’s ideal for your power wire to pass through the fire wall
Do I need a in line converter or do I just tap the yellow braided wires
That probably sounds like sh!t 😂
