Hello guys so I have a problem with installing my aftermarket radio after hook up the wires correctly (note that I'm not using any adapters because wire where cut by previous owner) and turning the radio on I only get sound out of the right speaker on the dash (with the left front speaker disconnected) but when connected I get no sound at all ...also with the left front speaker disconnected and when I fade the speaker to the rear I get sound but when balanced I only get sound in the right front ... On the dash. ... I checked all speakers and wires and they work ....also the door speakers are not working at all but when tested they work

 

I would double check the wiring again then.
