I was looking at a Boss Audio Phantom PH4.400 amp that claims 4 X 160 watts RMS (Total: 640 watts RMS). When I checked the fuse rating, it was a total of 40 amps, which would only merit an 8 gauge power cable.
I would have thought that a true 640 watts RMS would require at least a 4 gauge cable installed with a 120 amp inline fuse? Besides all this, I've noticed some don't care too much for Boss Audio. What do you think?
