I have a 1ohm amp but using as 2ohm. amp is hifonics bg2200.1d 2200w 1ohm, 1100w 2ohm. which size wire and fuse needed at the distribution block when just at 2 ohm? recommended at 2awg trying to see if 4awg would be fine since im only using it at 2ohm loading it with 2 4ohm svc 500rms wired down to 2ohm.
