i just bought this amp today from best buy brand new... i hooked it up to my infinity subs and it hit hard and sounded good for awhile... i wnet home and killed my truck and came back into town and it started like stalling out but coming back really i thought no big deal. but then it started shutting off for a long time... and finally would come on then would shut off and the Protect Light would flash every 4 seconds. so i called best buy and they said they would give me a new one for free... i poppped the hood hood to look at the fuse and the plastic part was melted. its like a metal fuse and the plastic part that covers the bolt was melted.. so i dont know if thats good or not... and my amp kit is all dB drive stuff... my ground and battery are 4gauge and the booklet says nothing over 6 and my speaker wire is 16 gauge and the booklet says nothing under 16.. so am i ok thr??? idk... it could be my charging system too.. im getting a mew battery 2mor and gonna get my regulator on my alt turned up hopefully this will help the new amp... and im gonna let best buy install it correctly... but i checked my wires and it was all correct... it puzzled me... any ideas???

i don't know, whats the vc of your subs, maybe you had it wired to the wrong load for them. could be your alt., but that amp shouldn't have killed it unless it was already going.
