So today I noticed my subs shut off so of course I went and checked, not only did I find out my amp was using 2x 25 fuses when it req's 30 but they were blown.

So I went and grabbed 2x 30's and here is where it gets weird, the second I put them in they pop. Like the instant it touches it pops.

I checked my ground and that seems fine, my battery is sending 12ish volts and I cant see any other problems.

I've read it could be a short but I don't get where the short could be from.

Power and ground are backwards or something.. Make sure your power wire ins't grounded out somewhere in the car.

Lol, if they popped because the amp was on when you put them in, that'd make sense to me.
