This won't happen for a while, but I'm curious. And I'd be upgrading slowly, so I could only buy one thing at a time. I have the factory premium system. What would give me the most 'bang for the buck,' a new stereo or new speakers? I don't want a huge system. I just want to upgrade the stereo and door speakers. Maybe the subwoofer or put an amp in it's place if possible. I don't know much about car audio, so I'm not sure what can be done.
Also, if I did do an upgrade of the speakers and stereo, could I use the existing wires? Or would I have to rewire? Thanks for any help.
