[QUOTE="n2audio, post: 8247135, member: 540940"] For the fuse Nazi's trying to pinpoint an amp's power capability based on the current rating of the fuse. Opening time specs for APR fuses: 110% 100hr min 135% 3/4sec to 30min 200% 150ms to 5sec 350% 80ms to 250ms 120A fuse protection can pass ~130A basically forever. 140A probably for a few seconds. 150A on a burst One of the carsound engineers once explained their max power testing procedures in the lab and how they commonly had to replace the onboard fuses with shorting bars because the constant nature of the test would blow the fuses, but they were perfectly adequate for music, and provided some protection in the car. Fuse size power approximations are only accurate enough to give you ball park numbers on a dirt cheap brand with jacked up ratings. They're not of much value for a quality amp.
