I noticed that the jbl is a class ab amp while almost all of the others I have looked at are class d. What is the difference?
the difference is efficiency. a/b tipically is around 50% efficient while d is in the neighborhood of 80%. what that mean is, a class a/b amp with 100 amps worth of fusing can produce a total amount of power = 1440 and about 720 of that is usable power. a class d amp with a 100 amp fuse will be capped at the same 1440 but essentially will give you 1152 usable watts.
what that translates to, is a class d amp can give you more power with less of a current draw on your cars electrical system than a class a/b amp.
