What about your ground wire? Good clean same size? Also do you have a fuse right after the front battery on the line coming back? If not then you should as if that wire gets grounded it will burn anything touching it......... You may also try a higher amp fuse as well, as I recall I used to blow more in the summer heat than any other time.

Are the wires touching each other where they go into the amp?

If the wires were touching, then the fuse would blow instantly. The question is, what fuse is it that keeps blowing? That way we can tell where the surge is coming from to blow the fuse. if it is the fuse between the amp and the battery in the trunk, or if it is between the battery in the front and the battery in the back. Electricity is like water, path of least resistance.

OK,
So you just need to separate the amps onto separate fuses to reduce the draw over the 80amp fuse, or add another fuse infront of the secondary amp.

Basically a power distribution block making them each have there own power source and fuse as well.
