hey can someone help me out, i've got 2 amps running, one says its 30x2amps and the other one is 25x1, i've currently got a 60amp fuse and im guessing i gotta change it to a higher one the big amp thats running my sub (30x2amps) can draw enough power for optimized performance right??? anyone know what sizes fuses come in??? do i need a exactly 85amp fuse if they make one or they go up by 30??? (eg 30-60-90). how higher can the fuse ampere rating be than the total for the emplifiers without short-circuiting them???
