I just installed a pioneer head unit....hooked it up and it worked fine....just recently had my cousin install an amp (kicker 350.4 to the front and rear speakers)....figured he would be good at it since he did his own system...anyway.... hooked everything up and i think he crossed one of the speaker wires up...and when he went to try it out fuse blew and a good bit of smoke came out of the cd player...... then i rewired it back the way i had it before when it did work...everytime i go to put a fuse in it keeps blowing...so im thinking maybe i need another new cd player now... i tested out the 12 volt memory battery wire(YELLOW), the acc wire(RED)...and the ground wire with a multimeter....did have a problem with the ground wire..seems it was a little loose at the harness connection..anyway...fixed that an tried it again and it blew the fuse again..so does anyone have any suggestions? Do i need to get a new cd player now or what? Any advice is welcomed...Thanks
