was thinking just 12v, but it's more efficient at 24v right?

Technically no. Anyways, power consumption with normal music signals is: (supply voltage)^2 / (impedance * 16) + (supply voltage / 5) Edited by Saturnus - 08 April 2011 at 4:07pm |

(12v^2)/(4R*16)+(12v/5) = 4.65

4x the power, 6db more output / more headroom
as i dont need to run for long periods of time (10 hours max) then it works well for me
