window fuse keeps blowing

[tonsofunburns]

I have a 93 s10 blazer 4x4 4.3L(engine code W). I have blown 7 window fuses in the past two days. Sometimes it will fun all four windows at once and sometimes I touch the switch and it blows. It has an aftermarket alarm/remote start and an aftermarket stereo with subs but the subs aren't even hooked up. I don't even know where to start with this. It's not just one switch they will all blow the fuse. The only other thing I can see that doesn't work when the fuse is blown is the rear hatch release but this will not blow the fuse if it is pushed.
