Rcd 310 stock headunit. Amp and subwoofer installed. Amp and sub work. Front speakers work. Rear speakers not registering with the headunit after install, but I'd the sub works the wires are fine. Just a headunit problem. What should I do here guys. I really need some help. Why isn't the headunit picking up the speakers annymore?

 

Only thing I can think of off the cuff is maybe when you tied into the speakers did you accidentally severe the wires...so speakers not getting signal from those wires???? maybe accidentally snipped to far into them. Just a thought -unfortunately from experience.....
