    I've got a Mission MS8 sub which keeps blowing the internal slow fuse every time i plug it in, wondering if you guys may know what could be causing the problem?

    cheers

    You would get more help in the normal subwoofer area I think. It could be any number of issue causing this. First thing to check is that the fuse is the correct rating, if not and its too small then that would cause it to keep popping. Failing that there is probably a fault in the amp somewhere that would need looking at.

    If the fuse is blowing it is often down to:

    1) The subwoofer amp is faulty.

    2) There is a problem with the subwoofer connections causing a short circuit e.g speaker wires touching together, wires grounding out on some metal or a damaged voice coil causing a closed circuit.

    If you have a multimeter and can get to the wires you can set the multimeter to Ohms and measure the DC Resistance of the woofer. If it is approx 3 to 8 ohms then the coil should be fine.

    If it reads something wildy different or no reading then it could be damaged.
