2002 Yukon Denali Wiring

[Scuba 10+ year member]

wassup guys. i have a customer with a 2002 yukon denali. put in a stereo using a Pac OS1Bose interface, and the rear speakers did not work. we tried everything we could think of, and even spoke with Pac's tech support for hrs. no resolution. To fix the problem, we ended up bypassing the factory amplifier. problem is that we lost the subwoofer, and i want to get it reintegrated with the new deck. anyone have any wiring info on signal from factory deck to amp? if we can make use of sub control on deck, that would be icing on the cake. were going to fight with this today, im just trying to get a head start and reduce my techs headache. thanks all.

Have you Checked The12Volt.com?

Well If anything. On the amp should be Connetor 1 gray in color.

Pin A is Lt/grn Rear subwoofer negative

Pin B is Dk blu/wht Rear subwoofer Positive.

Both are outputs to the sub.

its the Y91 code. i think i may be an XL. on the door where model is listed - K15706

what im looking for is a little help in tracking down the signal wire from the dash that goes into the bose amp in the back. i want to try and feed signal from the new deck into the factory amp and hopefully keep it bumpin. if that clarifies what kind of help im in need of. thanks.
