inm Posted April 20, 2011 Report Posted April 20, 2011 How do you calculate how much power you're getting at certain Ohm ratings? Like, if I had an amp that does 1600 @ 1Ohm, 1100 @ 2ohm, and 500 @ 4 ohm, how much power would it be pushing at 1.33 ohm or 3 ohm? Would I just kinda of estimate how much power it's pushing, or is there an actual mathematical equation I can use? Thanks...

speedball1978 Posted April 20, 2011 Report Posted April 20, 2011 its called clamping. get a clamp meter and a dmm, to get actual power output, take whatever (i believe AC amps)amps you're getting from speaker wires x ac volts that will give you your true reading, but you want estimates.. 1.3 should fall around 1300 and 3 ohms probably around 750
fecupe2001 Posted April 20, 2011 Report Posted April 20, 2011 The only real way to know how much you are really getting is by "clamping" your system using a DMM and a clamp meter to measure the impedance rise...

inm Posted April 20, 2011 Author Report Posted April 20, 2011 Well, I just want an estimate, an equation I can use for while I'm shopping for a new amp... Just to get an idea of what kind of power I'll be seeing at the two Ohm ratings On 2/28/2013 at 2:52 PM, Chaise said: "Now spread your butt cheeks so I can zap your asshole." 2008 Subaru Forester XT

95_1500 Posted April 20, 2011 Report Posted April 20, 2011 Output voltage squared divided by the ohm load.. Ie if your amp is putting out 60 volts AC and subs at 1 ohm is 3600 watts. But yeah what they said because of impedance rise you will be higher than 1.3 or 3 ohms. Original Build http://www.stevemeadedesigns.com/board/index.php?showtopic=24095
