Blowing fuses too easily

[Mustang1999]

I have a 12inch kenwood sub and a pyramid America amp and I have had it in my car for about a month now and it was working great with amazing sound but now all of a sudden I went to turn it on and the sub wasn't working but the amp was on then I went to check the main wire power cable fuse and it was blown so I took it out and when I tried to put the new one in it sparked and blew that one too the I tried taking the negative terminal battery cable off then I put it in and once I put the cable back on the battery the fuse blew again why is this happening and is there always supposed to be current flowing through the power wire? Please help

Sounds like you power wire is making contact with ground (short). Check your power wire to make sure there is no damage/breaks/cuts in it.

Thank you and is this why I have constant wire running through that cable ? Could I have a bad ground for it to short ?

remove the fuse. go to the amp remove the wire from the amp. make sure to tape the end of the wire so that it doesn't touch anything back there. go replace the fuse in the wire. if it still blows you have a problem like legend said. if not then it's probably the amp.
