2022 Yukon AT4 wants BASS

[Trey Hardy]

I talked to my buddies they said they deleted the main battery all together because the stock battery or agm battery would drain down the lithium if their all connected and that the new lithium cells would be the new main battery to run the truck

Better pics of Chris’s wiring setup

I’m pretty sure you do away with the battery if I’m not mistaken I’d have to check with my two buddy’s I haven’t actually done this setup yet but a couple of my bass head buddy’s have and had great results. Plus the lithium is supposed to last 10years or so supposedly over a normal battery which might get what 3 years? Before needing to be replaced

What do you mean do away with...as in remove the stock battery or just leave the stock battery alone, drop in the lithium, wire up amp/LC2i to the lithium and call it a day? If not connecting in some fashion to the stock battery, how does the lithium bank recharge? As in the videos ive watched, they said dont mix AGM and lithium...so slightly confused this moment lol.

Yes you completely do away with the stock battery and the wiring for it and run new wiring directly from the inline fuse to the lithium bank and ground it underneath where you mount it at by running bolts through the frame or finding a good ground point that’s already there I’ve used seat bolts before for amps but not for something like this.
For our setup a 6 bank lithium setup would be plenty and a stock alternator should handle it fine chris has I think 10-12 but he also has 20,000 watts in his Tahoe

[Trey Hardy]

From my understanding you put a battery delete or “distribution block” in place of the stock battery pretty much a empty case

Going the Lithium route might be the best route to go, but seems like alot of things to do and then maybe also needing an alternator (over the 170amp stock) upgrade. Me knowing me....once I get done with a project, I change my mine. So with that being said, I think i'll just keep it simple to gauge my interest long term and just got with an additional AGM 12v XS Power battery.

Can snag this local for (asking) $300: https://www.amazon.com/XS-Power-Battery-Top-Post-Terminals/dp/B074T3RX2Z

if you wanted to just add a lithium bank of some sort you could just run a 2nd alternator and have it charge the lithium only. then you could leave the stock battery and everything else alone. the lithium would be seperated and the only connection to the stock system would be a trigger.
no trigger-system off
charging only when the alternator is spinning.
no discharging otherwise.
you would probably just need to add some kind of regulator for charging the lithium properly

I believe he does have some sort of regulator but there’s also a piece that goes and wires to each lithium cell to evenly charge the cells without over charging them they call it a LTO balancer

ya I browsed thru the video and saw the balancer purpose

Ordered:

Now to figure out which 2 wires on the stock amp are the sub wires to connect to the LC2i Pro ....

Off to mock up something to mount the amp to.

 

[Fast_AT4]

Anyone know if this is the same wires to connect into for the Yukon that needs to connect to the LC2i?

probably not, depends on your radio amp, the silverado's are wired different than the suv's
for instance mine has no center console so the front door speakers are filtered as sub's in the factory setup, I bypassed all of that nonsense
you will want to scan the door qr code and check the glove box for the rpo code's and get your amp model and look for a diagram for it.

Door QR(s) scans to VIN.
Only QR on glove box is the actual PN for said glove box.

This site would have been perfect, but not for 2022's

hmm, it appears they changed or deleted the link, before you could scan that qr and it would give you the rpo list.
probably happened when gm online tech support stopped providing it as well
now you have to get it from the dealer.... they can print it out for you, they might tell you over the phone if they know you.

Trying via GMC chat this moment, but if needed when calling the dealership...what specifically do I need to ask for? RPO codes for Bose system or other/more?

 

[Fast_AT4]

provided via GMC chat. Doesnt seem to be specific to my VIN though.


edit, looks like i'll have to call the dealership:

just your vin number, chat is useless anymore they cannot provide the build sheet. Only the dealer
UQA may or may not be helpfull as that number has been used for 20+ years
once you have the whole audio system number the best source for a wiring diagram is a good local popular audio dealer because they have subscriptions for accurate diagrams.
but sub output from the stock amp shouldn't be hard to figure out

Call my local dealership and they also gave me UQA code. #ChasingTail

uqa is it then, i guess it just depends on how many speakers you have then.
6/8/9/10+ and the year/make/model
