2002 DeVille Base Sound Upgrades
Hello, all. I am looking to upgrade the sound in my 2002 Base Deville (non Bose / non Nav).
This is what I want to do:
Keep the factory head unit
Upgrade all speakers
Swap the factory amp with an aftermarket unit
Add a subwoofer box to the trunk.
I know how to upgrade the speakers and add a subwoofer, but I don't know how to swap the factory amp. If anyone has done this or knows how to do this and could share that information, that would be great! I have looked around a lot on this forum and have not seen much clear information on this.
Re: 2002 DeVille Base Sound Upgrades
You do know the factory amp controls all the audio settings (like volume control) based on the information received from HU on the data line. There is no aftermarket amplifier that connects to the car data line and understands the protocol.
