[QUOTE="Tenacious, post: 8006596, member: 642017"] These amps are 76% efficient at 1 ohm and 84% efficient at 2 ohms. So... 1 amp pushing 2000w @ 1 ohm = approx 191 amp draw at 13.8v 1 amp pushing 1200w @ 2 ohm = approx 103 amp draw at 13.8v 2 amps strapped pushing 2400w @ 4 ohm (each amp seeing a 2 ohm load) = approx 207 amp draw at 13.8v 2 amps with gain set to 2000w with DMM with same setup as last calculation = approx 172 amp draw at 13.8v You may say this isn't a lot of difference... but 175a is the max fuse rating I can use to stay in my current class in MECA SPL competitions, so it actually makes quite a bit of difference in my case.
