I just discovery that one of my subs stopped working, not sure when it happen because I have 2 of them, but it is definitely dead.
I remove the sub and the amp to test them, Amp still good, tested the sub with the other amp and no response!
Where can I buy a replacement sub? I was looking every where but no luck, I need Polk audio RD50 55-2
I got them both from Circuit city so no warranty from them for sure !
