All right first let me explain what I have set up in the Jimmy. I have a kenwood d-mask cd receiver running 2 4" Kenwood speakers in the pillars. Have 2 10" in a box mounted in the rear of the truck being powered by a Sony amp underneath the seat. Here is the problem: Over the past 2 months I have blown 6 fuses that control the power going to the amp. I have a 80 amp alternator to power my accessories. Why do I keep blowing these freraking fuses to my amp. It was working fine yesterday afternoon, but when I got in it this morning I heard it start up then nothing after that and I had't even turned the truck over yet. Any comments would be appreciated.
