Allright,well i just got my wife's amp in for her RE SRx 15", it's a crunch PZI 1500.1D, well i checked the fusing before i bought it,30x4 ,so that worked out ,well i was checking the manual and it showed the 1000.1d to be fused at 25x4,then i saw that the 2000.1D had one 80amp fuse, and the 3000.1D had 50x2, how the hell does that work?It just doesn't add up,maybe i'm missing something,what do you guy's think?

 
If they are made for burping or something it would explain it. Fuses can take double their rating for short bursts. There was a thing on here with some guy talking about not judging amps based on their fuses.
