Displacement for an average 12" is about 100cu in so a 6.5" must be about 1/3-1/2 or so of that.

Hey, I have alot of important questions, but it's hard to get someone's undivided attention on here. You think you could help teach me a few things before I ruin my sub and amp? If so, let me know. Thanks alot.
