my friend is lookin to get a cheap system. I tried to get him to spend more but hes not so he wont spend more then 100 bucks, I know nothin to really work with. I found a Pyramid sub for 40 bucks online, again i know it sucks, but work with me. The sub is rated at 600 RMS and its 4 ohm and thats what were gonna use. now what we need is to find an amp no less then 350 watts RMS for under say 80 bucks. all help is appreciated.
