Wheres the effiency equasion part of it??... Flakko....!!!//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

K I changed it for the rated power...

(3000*1.1)/14.4=230

3000 is the rms power. Multiplied by 1.1 for 90% efficiency. 1.3 would be 70% so you catch the drift. Then divided by the voltage gives you current pull.

I'm pretty sure that's right iirc.

BTW I believe that in reality you wouldn't be pulling that much unless you listen to your music at full blast all the time...

First off, this next question is not meant to be a iggnorant comparison.. BUT, How would the heavilt underrated RF T4000bd stack against the ax?? early tests show around 4600 rms @13.8 volts.. Obviously it's less efficient and a bigger amp, But what is the main price difference .. $1600-$2800.. And from what ive seen and heard the power series of RF is also a very good underrated amp, just curious..//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

The powers are monsters, the 4ch is bigger than most 1 channels

So is the rf more powerfull than the ax at a cheaper price??

Still curious...

I'm not about to drop5 grand on 2 amps that i could get the same power from 1 1700 dollar amp
