I just installed a sony explod system in my honda civic and found out i have no signal in one set of speakers in the rear. I tried reversing the RCA cables from the head unit and found it just made the same set come on again. I tested the RCA cable for failure and found it intact with current flowing through both lines. Can anyone tell me what i'm doing wrong, i cant live with mono for much longer.

 

the problem is not in your rca cables. basicly your saying 3 out of the 4 speakers are working in the car?

 

oh, yeah

 

well i have two 12"subs and two 6"x9" in the back as well as two amps and only one sub and one 6x9 work

 

look to see if the amp is nfg or the deck or are all the wires on ?
have you looked at the speaker see if the wire is hitting the car ?
