One day, all of a sudden my amp stopped working. I inspected the battery terminal and noticed their was corrosion on both terminals, cleaned it off, and I inspected the fuse in my positive wire for my amp and noticed the fuse was blown, replaced it and the amp would still not power on, I reinspected the fuse again and it had already blown, I replaced it once more and it did the same thing.
some were in your system the power wire running the amp is hitting ,ground and blowing the fuse,or your amp is crapped out.are the fuses in the amplifier blowing too.i would hook up another power to to amplifier out in the open and see if your having the same problem.if you do its the amplifier if its all good re run another power wire.with a distribution block and go bigger with the wire size,and you can down size the wire from the distribution block to the amplifier.hope this helps.
Theres a short either in the power cable or in the amp internally. Make sure theres in no portion of the cable thats rubbed through. Its more than likely a short to ground, or something internal to the amp. Make sure the fuse has the proper amp rating too. good luck
