I dont really care if its a monoblock or a 2 channel amp, or anything high-end or amazing quality, but im just looking for something cheap and roughly in the 400 - 500W rms range at 4ohm. Even if its a 2 channel that is 400rms x 1, just as long as its at least 400rms @4ohm.
Im looking for something roughly around the $100 mark, so probably no major brand names or anything. Im not too picky about this one.

Thanks in advance
