recently i bought an amp for my front speakers. i spliced the speakers wires ran them to the amp and got everything hooked up then when i turned it on i was turning up the level on the amp and all of a sudden it sound like the speakers blew. i would understand if it was just the front speakers that didnt work but theres no sound coming from the back ones either. i hooked nothing up to the back speakers. the sub still works but thats it. theres no fuse in back of the cd player i checked, and i checked all other fuses. does anyone have any clue what i need to do? thanks
