[QUOTE="dB-r, post: 6219795, member: 574699"] LOL. 4000 watts on 160 amps of fusing.... I wonder how they do that? I know fuses don't blow fast (32V car fuses) but, seriously, 277 amps @ 14.4VDC = 4000 watts... Now this amp is definately not Class D, it's Class AB. And likely at 100% max power it is only 66% efficient, so if that is true, would need what, about 120 MORE amps of current at 14.4VDC to produce 4000 watts at 14.4VDC, so that would be around 400 amps... Now how can you squeeze 300-400 amps through 80 amps of LittleFuse? [/QUOTE]
