I heard AudioBahn aren't that bad so those would obviously really pound, but I don't like getting things without listening to the quality of it first so I don't have an opinion on those.
If you're going to power 2 subs, you're gonna be looking at at least a minimal 300W amp, but again it depends on what you get. 300W is pretty good power to 2 10" or 12" subs, but some people prefer more which pounds harder. http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=10724
I've had good experience with Kenwood amps and would recommend them to anyone, they give off a good amount of power for an awesome price.
