clarion problem

So I recently swapped out my old Clarion unit with a Clarion 755MC. Everything seemed to go fine reconnecting the main wires onto the new wiring harness and replugging the subwoofer RCA, Front/Rear RCA plugs into the appropriate outputs on the Clarion. But I can't seem to understand why only the left side speakers are working. I've checked the Balance on the deck, its set right at the middle. Nothing has changed in terms of wiring from the current amp to the speakers, only a HU swap. Any ideas?

are you using amps?  could be bad RCA preouts.  could be bad speaker outputs on radio.Jared Nixon - A.K.A Jsmoke

Yeah thats what I've narrowed it down to because the wiring to the speakers from the amps has remained untouched. My guess is the RCA outputs on the headunit are bad.
