Hi all,I've just purchased a 2008 Vauxhall Antara 2.0 cdti se,my problem is that I can play loud music from the front speakers but when I fade it to the rear the volume is really low and tinny like there's no bass
I've got a similar problem but mine is on the right speakers (front and back). I've tried a new speaker but that didn't do anything, also tried another head unit. Get good continuity on the wiring. Did you manage to solve it?
