Class A/B amps are typically full range stereo or multichannel amps that nowadays are used primarily for powering midbasses, midranges, and tweeters. They are not always as linear as Class A but are more efficient. Class D amp are limited in the bandwidth they can "accurately" reproduce. At higher frequencies, nonlinearity of the Class D circuitry becomes audible and sounds really bad. They are typically limited to 500hz and below which makes them suitable for driving subs and nothing else. The plus for the Class D amps are they are very efficient compared to Class A and A/B amps and allow for more power to be delivered to the subs with less draw from the car's electrical system. For an SPL system, Class D amps are almost a requirement, becuase they are the largest amps that can be easily powered for a 30 sec max effort run. For a SQ system, you can go with either type of amp for the subs, but the mids and highs can only be powered by a Class A/B.

Thanks helotaxi, i have always wanted to know that!!! Well done!!

What about class B/D, what is a class B/D amp good for?
