[QUOTE="Phreaker, post: 2151595, member: 567899"] they don't do rated power though that's the only bad thing. Someone benched the PA A2400DB and hey said it benched 1250w RMS @ 1 ohm when the **** thing is rated 1800w RMS @ 1 ohm...others claim theirs benched1300w RMS but either way be careful setting your gains. Also all I have seen the PA A1000DB's rated for is 600w RMS x 1 @ 4 ohms and 1000w RMS @ 2 ohms. What's the max amp fuse rating on the PA A1000DB?The PA A2400DB has 4x 40 amp fuses on it so a max fuse rating of 160amps. My look at it seeing as they have been benched at 1250-1300w RMS is like this... 160amps x 14.4v = 2304w PEAK/MAX 2304w MAX x .75 (75% amp efficiency) = 1728w MAX/PEAK 1728w MAX x .75 = 1296w RMS @ 1 ohm 1296w RMS x .75 = 972w RMS @ 2 ohms 972w RMS x .75 = 729w RMS @ 4 ohms This is no way to calculate an amps RMS wattage though..there are two ways and unless you have the major boku bucks the second is your only option. Get a DMM and a Clamp Meter. But I wouldn't doubt that the formula would be a close bet with the DB series PA amplifiers. [/QUOTE]
