what size speakers come stock in the 2003 cadillac deville?
Frenchie, technically you could connect your 2003 Cadillac Deville amplifier turn on wire to the radio switched 12v+ wire. That way your amplifier is on whenever your 2003 Cadillac Deville is on and off whenever your 2003 Cadillac Deville is off. Just make sure to run an in-line fuse holder with a 1-amp fuse on the amplifier turn on wire. Hope this helps. Good luck with your 2003 Cadillac Deville amplifier and subwoofer installation.
