04 cadillac deville, stereo, wiring

Hi.  I have a 2004 Cadillac Deville and am basically looking for any advice, comments, or concerns with the equipment I have chosen.  I have purchased a pioneer AVIC-F900BT in dash screen.  As far as amps and speakers I am looking at JL A6450 to power 4 JL 525Cxi and 2 tweeters (still undecided) and a RF T10001bd for 2 JL 12W6V2.  I am upgrading the Alt. and wires but any information would be appreciated.  I have pulled a cadillac apart before (94 SLS) so I am not too worried about running cables or pulling panels.  Thanks

I am trying to find a pin out for my 04 cadillac deville's radio harness.  The actual harness that plugs into the back of the radio.  If anybody knows or can point me in the right direction I would appreciate it.  Thanks

Installing a radio in that vehicle is not like it was 10 years ago.  Metra sells 2 different harness options for that vehicle.  The GMOS-06 in a harness designed to Utilize the factory amplifier, and retain door chime and provide you a switched 12 volt wire to connect to the red wire of your new radio.  If your radio has front and rear Preamp outputs, this would be a good choice for your needs.

The other harness is an amplifier bypass harness.  It has to be ran from the amp in the trunk of the vehicle, all the way to the radio location in the dash.  It uses the internal amplifier of your new radio.  The amplifier in the trunk of the vehicle probably has a bit more power.  70-5024 is the part number of that harness.  I do not think it provides a switched output for the red wire of your new radio, but it may.  I am sure that if I am wrong, someone will point it out for us.
