I had gave my amp a 16 volt input, then there was a spark which came from fuses that got burnt. I then replaced the fuses, rewired it nd gave it a 12 volt input it came on and went on protection. So i left it aside and after a few days i tryd connecting it again but this time it came on and it was burning the power cables no matter what guage wire i used. Any idea why its doing that?
It's a 12 volt DC car-type amp ? Sounds like it's got a short inside. But, unhook all the other wires, all the speaker leads imputs, except for the power the ground. Have a fuse in one of those two leads, turn the amp OFF, hook up it. If the fuse pops right away, then odds are it is now a piece-'o-junk. If it sits okay, turn it on, with no volume. Again, if the fuse goes, trash it. If it holds okay, hook up ONE of the speakers give it a little volume. Even without an imput, you should be able to hear a bit of static, which means it's working okay. Turn it off try another speaker....etc etc
Look for a short circuit in the input power circuitry.
