Hi, I have a Polk audio rm6000be sub, when I connect it to power a led indicates that there is power but when I play something no audio comes out. Could it be the ic in the pic? (It’s a Tda7295) everything else looks ok and driver works (I tried with another amp)07az6cizhjv5.jpeg

    With the exception of bulging or leaking capacitors or burned resistors it's difficult to identify a problem by looking at a circuit board. Typically problems with subwoofer amplifiers are related to voltage regulators, filter capacitors and output ICs (the TDA7295). There have been quite a few posts here that recommend replacing these amplifiers with generic "plate amps" found at places like Parts Express.
