me and my boy having the brass ballz we do decided to rip out my interior and install an amp and woofer.
so we connect everything properly, (so we thought, and still do) turn on the car and low and behold only the right speaker works.
after trying different stuff we took it all back out and still only the front right speaker works.
please note we did nothing with the existing stock speakers.
ran a line from H/U to the amp to tell it to turn on and ran some rca's to the amp to provide the sound input.
one speaker is awful. I can no longer pimp through campus

any suggestions?
