Found out my 2 left tower speakers weren't working from the people that did my annual. They said the speakers were blown but they aren't stereo guys so I wanted to troubleshoot before ordering new speakers. Checked rcas, speaker wire & wires at the amp and behind the head unit. I wanted to launch so stopped troubleshooting.

So next trip out did a little more digging but still didn't have time to get into it. Swapped RCAs at head unit and the left speakers still didn't work, then I noticed 2 of my subs weren't working either.

They are both on separate amps so makes me thing it's a RCA splitter behind amp rack? But again I didn't have time to take the rack off.

Any ideas?
