Hi, I have a Hifonics Brutus BXi2008d class D mono block amp, I had it pushing 2 10 inch alpine type Rs DVC @ 4ohms (650 RMS coming from amp @4ohms) after about a month of use on the subs the amp quit working and started to smoke. I know that my amp does not have any internal fuses, I was just wondering would internal fuses stopped this from happening, and is there any replacement parts I can get to fix the amp myself
