I can get both of these amps locally for around $400-$450, im just not sure which is better. I am going to be using it to push a RE XXX 15" dual 2 ohm. I may switch subs down the road so I was thinking going with more power would be better in case I need it, but I haven't heard much about American Bass.

So I need input and opinions on the two or even suggestions of something similar that I may be able to find for around the same price. Thank you
