I just bought an 2003 Cadillac CTS and I have an amp and subwoofers that I would like to hook up. I don’t want to replace my existing audio system seeing as the radio not only controls the radio but other things in the car as well, so replacing it would make me lose all of the extras. It has a stock amp in it along with a stock subwoofer. It has a Bose premium system already in it that came with my 2003 Cadillac CTS. We have hooked it up, but can’t get it to sound that great. Does anyone know the wiring diagrams for the stock amp, or have any advice on how to do this? Thanks.

Answer: You can add the amplifier and subwoofer pretty easily in this vehicle; what you’ll need is a line-out converter, and you should connect it to the speaker wire between the factory amplifier and the factory subwoofer. This will give your amp the right frequency range to run aftermarket subs, and there’s no reason it wouldn’t sound excellent with a good quality line-out converter. You do not need any special modules for your “data bus” system since you’ll be tapping in after the factory amp. It would be a challenge to tap into the factory system between the radio and the factory amplifier, but the output signal from the amp to the speaker isn’t any different from any audio system anywhere, as long as you pick a speaker that carries the same frequencies you want your amp to carry. You can disconnect the factory subwoofer or leave it running; the new system will work the same either way.
