What kind of changes would I have if I went from a class D Subwoofer US Amps to a class A/B US Amps?

the amp would be alot less efficent and it would put more of a strain on your electrical system.probably run a little hotter too.

Higher current draw, assuming they have the same power output.

Other than that....nothing really.

So what do you all think about swapping the MD2 for a 2000x?

you have 1 stereo integrity magnum 12? and you're putting a US Amps 2000X on it?

these will get fine off 500 watts, no need for 2000+ watts

I don't think the extra 500w would be worth the increased current consumption.

The A/B amp is generally gonna have a lower distortion rate, but on a subwoofer it would be almost impossible to actually hear the difference. It will draw more power than the class D assuming they have the same output. Why are you thinking of switching?

I'm buying a second one //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

I dunno really, just to try somthing diffrent.

Stick with the MD2.

Both will give you ~1kw at the impedance you have to work with (MD2 ran at 2ohm mono, the 2000x ran at 4ohms/channel)....and the lower efficiency won't be worth the switch.

I actually have the md2 at 1 ohm right now on one mag, and when i get the second mag i was going to drop it to .5 ohms,

Not sure how stable those amplifiers are into that load......but, the moral still remains the same. No point in switching, expecially if you don't have a heavily upgraded electrical system. A 2kw class A/B amp is going to have pretty heavy current draw...more than most stock systems could handle.
