Ive never had a problem with a system until i bought my Crown Vic Police interceptor a few months ago.. i just recently bought 2 fi Btl N2 15s, and built a box for them. i had my rockford t4000.1 powering them with 2 xs power d3100s and a 220 amp HO alt. The thing is when i would turn it up it would cut out.. now it wouldnt always cut out, sometimes i got lucky and it would play for a minute at full tilt. I tried everything to fix it, from doing a new ground right to the frame to pulling all wires and everything out to double check..i thought maybe it was the 3100s doing it, so i disconnected them and just had my main front battery hooked up, and thats when my amp fried..
Could this be something to do with Fords power distribution box? or voltage regulator or something? I would love to know why this happened.. ill post some pics of what im talking about..
ALSO it got to the point were it just went from cutting out to where my back fuse between the battery and the amp would blow, i replaced it, and it blew again, i replaced it one more time and my amp went into protect and made a nasty noise..
