Yeah, I was just hoping to not have to rewire everything. If I replace the factory amp with an aftermarket, I'm assuming I'll either have to run all new speaker wires, OR hack into the factory harness for the speaker out wires?

I was planning on replacing the headunit soon with a bluetooth compatible receiver, but I hadn't really planned on doing anything beyond using the adapter to connect it to the factory harness and amp.

I'd like to be able to easily return it to stock if I ended up selling the car one day.
