check your wiring. make sure that nothing is accidently touching the ground somewhere. what fuses are you blowing? the inline fuse will be independant of what your head unit does. did you install the head unit yourself?

I would guess you have the gains on the amp set wrong ..... full power for the amp is probably around volume setting 20 or so.
