Ok, there is nothing wrong with running class D amps in any setup...period...You will see more current being drawn off a A/B a,mplifier over a more effecient class D. I'd choose class D anyday, in any enviroment. And for a steet beat setup, which the original poster probably has, class D is actually better.
I agree with Mackenzie here, the JBL 1200 is a nice piece for the money. Great output value, underrated, great little piece.
With a sub that is RMS 800, max 1600, 1200 is perfect, IMHO.
Class D is perfect, as sealed a driver can handle more power anyways.
For a good list of amps, stay in this amplifier section and look at 1000+ amps....big list with power, and prices.
