[DeViOuSoNe 10+ year member]

I am installing a Flip out DVD player in A 05 Caddy CTS, I want to knwo If there is anyway, I can keep the factory amp and use this headunit, WITHOUT buying the 250.00 harness. If not I will just run a different 4 channel amp, But really dont want too, adn does anyone know where I can find the wireing diagrams for this car, Color wise, and so fourth?

Thanks!!

I am using my factory amp just to power my rear fill. But my harness wasnt that expensive. You can try Theinstalldoctor.com for the wiring diagrams.

I don't think you can do this without an adapter. If you bypass the amp by wiring to the outputs of the amp, you will be loosing the amp. I don't know how the wire colors will help you keep the factory amp. It will just help you wire up the aftermarket amp.
