My amp keeps popin its fuse wit the radio off...i checked for shorts and nothin...only pops its fuse not any other....posible short inside?

your having some kinda of surge go through your amp. i might check the fuses under the dash to make sure there all the right amp rating. as well check all your grounds. a bad ground can cause the amp to pop a fuse if it can protect it self.

i switched the amp with one of my other ones n it works fine no blown fuses or anything and this amp uses low amprage fuses....

i will take the amp appart n see if i can see what was wrong
