I've unhooked the speaker and re-hooked it, nothing works, I checked the connection on it too. I ran the power, lead-in, and rca for the sub down the driver's side of the car under all the interior panelling. Could this be the problem or could it be the ground? I dont think the ground is to completely bare metal, but its been a while since i've checked it out. Any clues or ideas?
