Cadillac - Bypass OEM Amplifier - Add an Amplifier interface
Bypassing the factory amplifier is a more difficult undertaking but provides the best sound quality gain. When bypassing, it takes a more work because you have to run the bypass harness to the factory amplifier, which is often located in some other part of the car. Bypassing the factory amplifier will require an aftermarket amplifier or using the aftermarket radio's internal amplifier.
