    There could be something wrong with your wiring. I always blew the fuse on the battery when the ground wasnt good enough. It could be multiple things though, but I bet its not the amp. Check all of the power and ground connections. (sand the spot that you grounded to bare metal).

    Problem is the polk box is a 2 ohm load, your amp isnt 2 ohm stable when bridged. Basically ur makin the amp do somethin its not supposed to so its overheating and drawing too much current, in short eventually the amp will fail

    Solution - new amp thats a monoblock

    Penta is right. Youre putting a 2 ohm load on an amp that certainly isnt able to do that. You want to look for a mono block doing its RMS at 2 ohms.

    Anything from MTX, Rockford Fosgate, Alpine or Kicker in your price range that can handle a 2 ohm mono load and makes 600-800 watts RMS.

    just hook it up and it will see the 2ohm load from your box
    just ocnnect the wire from polk terminal to the amp
