Ok this is what happened i had my music on and i was bumpin and i turned it up and the music went out as if the amp shut off(it might of)...so i turned it down and the bumbs came back?? Anyone know what happened? Maybe a voltage problem? fuse problem? Amp over heating(ussually when this happens i shut it off for a while and then it comes back on but this came back on immeditely) This is what i have... four 12" directed studios and one 1500d directed amplifier.. I'm running 4 gauge wiring.. and a 60watt fuse in the fuse holder(they blow on certain songs..) i dont have the big three done and i have this all in a 98 blazer with a stock 105a alt? WHAT COULD BE THE PROBLEM?? Help! Thanks!
