After installing an aftermarket hu only the right rear speaker is working. Before screwing everything back together I tested the head unit and everything worked. 30 minutes later i turn my car on and only the RR is working. All the wires are connected properly so I don't get it. Any help is appreciated.

 

maybe when you were putting back together your center console you pulled/tugged the wires or they got caught/snagged and became disconnected.

did you solder your connections and tape them? or just twist together and tape? or crimp connect them?

I only suggest this because after replacing my headunit twice in the last month, I found the hardest part was putting everything back together, especially with extra wiring behind the headunit, as space is VERY tight. I had 2 sets of RCA leads to my amp, and other wiring for a remote radar detector and USB cable, along with the radio wiring harness, cable to backup camera, etc, and I had a ***** of a time getting it all into place and replacing the front center console.

 

Yeah Im planning on taking it back apart today and checking the connections again. As far as connecting the wires, I crimped them. Thanks.
