No difference. The mono amp will work less so better in the long runn.

Mono amps are ussualy for just subs right? But why do they work better in the long run if they push out the most power? Will it be cleaner?

Mono amps are for subs. There is no advantage of a mono vs stereo when it comes to sound. However, there are different types of amps. Class D are for subs, class AB can be used for full range and subs.

yeh and youre better off running class d amps if youre running a low ampere charging system. Class AB tends to take more power to run than class D's. I think its something like 20% amps more than clas D

Class A/B is about 60% effeciant, and class D is about 80% effeciant. However as I saac said you only want to use class D for subs. The way it amplifies the music is diffrent than a class A/B. This diffrence in methods, is why a class D introduces alot of distortion which is very easy to hear on mids and highs. However it isn't near as noticable on subs.
