jonatan Posted March 5, 2009 Report Share Posted March 5, 2009 anyone know whats the diff from:Class bd circuit topology to Adaptive class D circuitry how do you know what makes a good mono amp?

troy Posted March 5, 2009 Report Share Posted March 5, 2009 (edited) a company with a good rep or cea compliant is a good place to start Class D amps have higher efficiency, produce less heat, and draw less current than Class AB designs. Class D amplifiers do have higher distortion than AB designs , but this distortion occurs at high frequencies that are typically removed by a low-pass filter. So a d amp is probbably the best choice for a bass aplication Edited March 5, 2009 by troy Quote retarded build on the way..... 2000 bagged s10 2 hdc3 15s aq2200 aq4x90 stinger/knu wire optima batteries 220 amp alt fosgate hu/mids and highs Link to comment Share on other sites More sharing options...

troy Posted March 5, 2009 Report Share Posted March 5, 2009 no d circuitry and ab circuitry is two different things.

troy Posted March 5, 2009 Report Share Posted March 5, 2009 (edited) they still are not the same. its like asking if 2 and 5 are the same. class d is diff from ab regardless. its either one or the other not both where did you see a class bd amp?

Guest Posted March 5, 2009 Report Share Posted March 5, 2009 cea compliant doesnt always have to be CEA compliant to be good. sundown iirc isnt cea compliant but its a damn good product. Quote Link to comment Share on other sites More sharing options...

troy Posted March 5, 2009 Report Share Posted March 5, 2009 a hybrid basically. its basically a way of saying its a mono amp with a very clean signal. being that is what a class ab amp does. they produce a vey clean signal.
