First off, Im not sure if this goes here. So mods, please move this if it's not. Well, I'm going to buy a new sous system for my room. I want somthing that will really make the bass sound good, as I will mostly be listening to metal. I currently have 2 RCA 80 watt speakers. Ik I need a sub and an amplifier/reciver, but what else? Any help is appreciated.
