The fuses probably went as soon as you connected the main battery cable. Sounds like you have the positive and negative cables reversed. I did that last time I worked on my car Popped the fuse, but thanksfully that was all. Checked everything out and realised my mistake...

I can't figure out why the new fuse you put in didn't just pop though before burning up your amplifier
