class a/b !!!
I haven't studied the topic at all, but I ran across these in a quick search: Significance of slew rate - CARSOUND.COM Forum
2 Walmart batteries under the hood (recommended specs for my truck) on a GM 140 amp alternator (bought at AutoZone) ...
with all 1 awg/ 0 g welding cable ...
Front stage ... 2 Linear Power 2150s ... 150 watts per channel ...
sub stage ... 1 Linear Power 2250 ... 250 watts per channel, but running 8 ohms mono at the moment. Not sure what the actual wattage output is, but its VERY aggressive !!!
Here is an interesting take on Class A/B vs Class D from the founder and former lead engineer of Image Dynamics. (hint: it's probably not what you think...)

I have ran a/b amps since 88, and recently began to run d amps in one system, and a mixture of d on my subs,and a/b on front stage.i myself really cant tell a whole lot of real difference other than using an old zed made amp,which seems to have a richer deeper,cleaner sound,but they still sound very nice, my only concern of class d amps is,are they like the new digital tvs?being digital,do they only last a certain amount of working hours,then need replacement compared to a/b amps, that i have used for 15+yrs,without any issues?
If you buy a good quality amp and don't abuse it -- it's going to last.
If you buy a cheapo, and/or abuse a good amp it's probably not going to be around for long.
I don't think the class of the amp has much - if anything - to do with that.
My '00-01' Lanzar (Zed) class D is running fine.
