first don't remove your stock stereo if u havn"t already. The radio works with the carscomputer to reset codes and other stuff. you can get an adapter that turns your speaker wire on the back of the radio into left and right channel to hook up to an aftermarket amplifier. then hook up your new speakers and sub woofer to the amp and use the stock radio to get your grove on. or install an after market radio in the glove box or middle console but don't remove the stock radio. get rid of the stock amp not powerful enough.
The voltage regulator on your 1997 Cadillac Deville, is located on the top of the alternator. Some aftermarket alternators have the voltage regulator, on the back of the alternator.
The era gap is huge when considering a 1990 Deville to a 1997, no way is it possible unless you have tons of time to make extreme modifications and LOTS of money.
A Cadillac Deville can be purchased at a Cadillac dealer.
