Where is the amp in a 2000 deville cadillac?

The amplifier in a 2000 Cadillac DeVille is typically located in the trunk (boot), behind the rear side paneling. It's often integrated into the radio system and not a separate, easily identifiable box. You'll likely need to remove some trim panels to access it. Consult a repair manual specific to your 2000 DeVille for precise instructions as the location might vary slightly depending on the sound system options your car has.
