Hey guys I searched but got nuthin. I was wonder If a class A/B amp was more power hungry then a class D amp. I think I seen someone post that somewhere.

I was just wondering if it was true, because it would make sense because my amp makes my lights dim horribly and it's a class A/B amp.

Oh and BTW they would obviously be the same watts at the same Ohm load.

Thanks guys.

They are much less effecient, so they draw more current to give your subs the same power as a d class could drawing less current.

im taking out my passenger seat, battery is disconnected, going to unwire and take out the three amps, take out the 70+ lb box, then the platform so i can crimp 1 wire.

Almost as bad as those fegs that put those horns in their grills and roll down the street distorting the block....

Depends on the amps in question. Some (either class A/B or D) are more efficient then others in the same classes

Designing, building, and shipping boxes. Yahoo IM - kingsuv00If the listening level is too loud, please inform the driver, so he can promptly pull over, and let you out.

not many cars can get me to pluggin my ears but this one.......damn. I mean the first minute is ok but that thing just really starts digging deeper and deeper in your earhole till you cant stand it no more. Seems like it does it with relative ease....16 12's on 8 amps.........gotta love it. :)

A/B are usually cleaner amplifiers but are more ineffiecent

D class is usually not as clean but ALOT more efficient.
