My 2022 Tahoe Bose Audio Mods

Where did you guys ground your amps? Any Pics?

I used a self tapper into the third row seat frame. Easy to run the ground cable out of the front of the cargo tray and right into the space under the third row seat. It’s invisible and doesn’t interfere with the seat mechanism.

Where did you run the power cable through the fire wall ? Pics?

That's the price that it gave me ($122), but the shipping was something like $80. If you get the whole thing <$200, you've done well. Good luck!!

FYI for anybody still looking at these you can skip the $80 shipping and buy this bad boy on Amazon for $148.85 right now and free shipping.

Did you end up replacing the speakers or are you still using the OEM Bose speakers?

Hi All - In the process of getting parts together to install the JL Stealthbox in my 2023 RST. I have the 9 speaker Bose (non dash speaker), and am trying to confirm what T harness I need.

I found one form PAC but it says it’s not compatible with my car. Can someone confirm what T harness they’ve used and share a link?
