I was just wondering because It looks like it would be fun. I am 15 and have built computers, and all but not a sub. I think I can do it if I buy all the components but is it easy? I don't have a sub but I want one for my room. My budget is probably 160-200. I was probably going to get a dayton sub, or sony/velodyne. If I can find a good used one then I was going to get that.
