Ok, I have 2ga wire running from my battery to a fused dist. block, which runs 4ga to my cap and mono amp and 4ga to my other 4 chnl. amp. They each have 60a MAXI fuses and a 150a at the battery. When I turn my music up about 3/4 of the way, my 4 chnl. amp turns off, but my other amp doesn't. Anyone know why this could be happening? ps- I didn't blow any of the fuses either.
