Polk speakers problem: I got it!

[Baloo]

I had time to look closer today: the 4 rear speakers wires were snapped off when I dropped the speaker pod.

As suggested, I went in the side cover and checked the harness with an ohmmeter and found open circuit on all the wires. Opened the harness and repaired the wires, problem solved. I just finished the install: great improvement!

Thanks for the help!
