"luxury" amp transplant

[chaingun427]

Looking to see if anyone has ever transplanted the "luxury" bose amp and radio into a base model tahoe.

Also looking to see if anyone has a luxury amp, or at least a part number for one available.

I think for the 07-14 there is basically 2 different lux amps, you can find them on ebay, as far as upgrading I think you would be in for a job including a bose radio, complete harness, speakers & programming.
my tech2 will tell me the amp part number in my Denali but it's going to be one of the 2 that are readily available on ebay usually for around $100

Yeah I'm finding a smaller and a larger one on ebay. I think the larger of the two is the "luxury" amp I guess the real question is if I transplant the amp into my Tahoe, will it power on and pick up stuff like chimes, signals, and the speaker phone?

This is what amp is in my 09 Tahoe LTZ. It has Nav, rear entertainment, and Bose with 10 speakers.

I've got a 2008 denali too I'm going to pop the console and see what amp is in it, I'm stealing the motor and some other stuff and it's getting my afm 5.3 before I sell it, so I might as well try to snag the amp and nav

That's premium to luxury. Mine is base radio, no amp at all. I'm unsure if the bcm will signal to luxury amp to turn on if it's never had one in the first place

Why not just go aftermarket? A lot easier route and probably a better sound in most cases

Integration mostly. I haven't found an interface that I like for door chimes car phone, rse, and backup camera that I like, at all. Tried the maestro rr based on recommendations here and it keeps the steering wheel buttons great, but the chimes are ass and the rse is glitchy for some reason, but perfect when I go back to the factory radio

The pac doesn't have a feature set I like either

chimes are adjusted in the DIC, the bluetooth mic in these trucks is crap use one that comes with your deck, RSE only works with a deck that supports dual zone. I have the maestro, everything works fine with a pioneer nex and wireless android auto

Chimes and such in the base model are generated in the radio

So far have been able to get the amp to power on by tapping the amp circuit which is on x4-pin 6 of the I/P junction block in my 2012, as opposed to x3 pin 8 on the premium/luxury equipped trucks (confirmed after actually opening the I/P Junction block and manually verifying the circuit).

Installed aftermarket radio and idatalink Maestro RR, programmed for OEM amp, and i have chimes working like stock with no radio at all connected.

Next step is to move and rewire the speakers and low level inputs to get all of the sound moved to the amp, then upgrade the speakers themselves. Will post updates and a write up when i'm finished.

Decided to grab some pins and connectors from Mouser, and made an intermediate harness between my idatalink interface, and the original radio harness, this routed the low level sound down to the amp, and the high level out back up to the front speakers.

I was confused at first, because the rear speakers have no input on the uqa+y91 lux amp, the sound is matrixed from the fronts only and there is no fader control available (I have some ideas there, but nothing done yet).

Even without that, I have full function of the original speakers, + the bose sub. If I were going for all out sound, I'd probably replace all of the output wiring to the speakers with larger gauge, but this seems to be sufficient for stock and stock replacement.

Highly considering buying a uqs amp to play with as well, just because. Not sure if I'm going to add d pillar tweeters, or the front center channel at this time but it wouldn't be difficult to do so
