What are some amps that are as good or better then kicker amps....kinda lookin for things where you don't buy the name. I am was looking at the zx2500.1 but i decided that its just too much money so i am looking for some that are cheaper but put out that same quality stuff. Good efficiency is always a plus and just the little things that make kicker amps great (IMO) that some other not "brand name" amps have. Hifonics? good or bad? was looking at the ia20.1 but its a little pricy. I don't really want stuff like power acoustic......its kinda hard to explain but if ya understand just say some suggestions thanks......
