I want to get some ideas from all of you... I've been really wanting to move up to 2 15's now. 12's are great but i want bigger!!! lol What should i be looking at? budget? hmmm, not really sure yet but I a cheap bastard so something that will really sound good but won't break the bank.. I was looking at a pair Audioque SDC2.5 15's. Would that bump pretty good?
