The car I bought has:
- Pioneer MP3/CD player
- 10" subwoofer in box
- 800w Amplifier
- A pair 6x9" sony explodes 3way
- A pair 6" audio boss split speakers with tweeters
The problem is that the sound, even though it comes from both sides, only outputs the left sound (if that makes sense...).
I would expect that with the system I have I can listen to my music in stereo. When I asked the guy I bought it from, he told me I just have to rewire it. But the problem is that I have no idea

Is this setup any good?
And also if I put on too much base my rear window vibrates like hell.
(the boot lid has soundproff stuff on it)
Cheers guys.
