Amp Classes

[BDIDDY 10+ year member]

Just wondering if someone could explain the amp classes because I had someone looking at my 81000d and they said man your system is loud, that is a D amp right? I said yeah. He said thats why its so loud. I know that is not the reason, and I think it has something to do with power it uses and stuff like that. Any Help??

Thanks

so the small amps, comp amps and stuff like that are AB? Or does it depend on what amp you have? Also are all mono amps D class?

The fact that it's Class D is not why it pumps out so much power. Class D allows more power with less current draw. Because of the increased efficiency, less heat is created, thus a smaller heatsink will suffice (Unlike a typical 1500 RMS Class A/B amplifier which is friggin' huge compared to the 81000D) ...
So, Class D = greater efficiency, smaller footprint

Of course, this is a generalization and there are exceptions ... Some class Ds aren't very efficient at all (i.e. JL Audio's Slash series)

Thats what I was thinking I was just trying to get my facts straight before I told someone something wrong.

Thanks
