    well what is the power rating on the amp? take the RMS power of the amp at 2 ohms... divide that by 10... that is the size of the fuse you should have....

    so you got a 1000 watt amp, divided by 10 = 100 amp fuse you need.

    figure out what yours is... if you're putting in fuses that are too small then that is why they're blowing...

    couple of reasons you may be blowing fuses....
    1) most obvious is a bad ground.
    2) something shorting..maybe pinched during install
    3) improper connection with the amp/cap- seen this before
    4) as vinnie said(dodge) wrong size fuse
    5) too small of a ground 0r legth could possibly do it too.

    best thing to go over every bit of the install 2x to besure all is right....if that fails..may be a bad amp...wich with a possibility:rolleyes:
