Ok, i live in an apartment. I'm in college. I can't have a loud sub, and i can't afford much. I want a 10" becuase i think that at the volume levels i will have it, a 12" would be a waste of money. I currently am running Paradigm Titans for my fronts. It's not a big room. Can i build a sub with amp that will match well with my Titans, sound good, and not break the bank? Oh great DIYers, can it be done !?
