Hi I cant seem to find info about adding an aftermarket amplifier to my HU

Its for a 2005 Yukon Denali with the DVD Navigation Touch Screen with the Bose Premium Sound System + Onstar

1 - Will the PAC-C2A-GM24 work with my system?

2 - Will I lose any of my features on my stock H.U.?

3 - Would there be anything else I would need after that?

I just want to add some 12" subs in the back...thanks in advance for any help you can provide me.

I'm not familiar with the PAC stuff but here's some ideas. You will need an On Star adaptor ( there are many ) and a hi level to RCA step down. The factory speaker leads can be accessed under the center console , tap into them after the amp. Your colors should be standard GM R+ dark blue, L+ brown, R- lite blue, L- yellow. There is no turn on or switched lead here so I would use a speaker level low voltage turn on.

Okay, you dont need an OnSar adaptor to add a sub amp in that vehicle. Use a quality LOC after the amp on the sub outputs of the factory amp. Also you should be able to find an amp turn on lead also. It is an analogue turn on, not digital like many people think.
