I recently got a new car and moved my system from my old car, I hooked it all up and everything was working fine. Two days later the 20 amp fuse on the power wire blew so I put in another fuse, Now it just cuts the sub off, it will turn on for a second or two then it just cuts off. I turned the gain all the way down then it works but not loud enough for anyone to hear it unless you have the trunk open and your head in the trunk...lol If anyone can help, Thanks in advance! - Vince
If the amp stays on with the input turned down, I would check or have the sub woofer checked speaker for resistance and impedence to make sure that the speaker is not damaged. If you take off the speaker and turn up the amp and it still cuts off, there is a problem in the amp itself. Most likely a problem in the differental circuit of the amp. Have a pro take a look and bench test the amp. GOO LUCK

Some type of over-current protect device in sub amp section gone bad..perhaps a board-mounted resettable circuit breaker or fuse has gone bad? these are hard to locate on the board for a novice.
