1999 Cadillac DeVille

i posted this elsewhere but i think here would have been better...

anyway Tuesday night im doing small system in a 99 Caddy Deville. front, rear speakers; tweets; and a Pioneer head with XM receiver and of course, XM antenna.

im predicting this to be a Bose system. the old 91 and 92 devilles would have me run speaker wire to all speakers to bypass the individual amps. in the 99's, are the amps still on the speakers or did Bose wake up by then and do a centrally located amp.

is there anything in particular that anyone can think of that i should know? if the amp is centrally located, is there a bypass plug available? any one have an idea as to what the color codes will be on the amp? i doubt they are going to be the conventional GM wire colors...

that's my post.  the title doesn't show, but it's directly related to the hell of a '94 Deville Concours install.

also, if you haven't located a dash kit, chances are there isn't one to be had.  don't be surprised if you're fabricating some isht for the dash.  and you might be better off with a deck that has the pre-amp outputs wired away fromt he deck (you know, those 3 - 6" preamp leads) instead of one that has the preamp outputs in the decks chassis.
