Bazooka systems are always impressive.... but it takes the fun out of building and designing an enclosure....
I think you were on the right track with the Blueprint decision. Instead of the 01 series... check out the 02 series. I'm pretty sure they offer a 10". The price jumps a little, but it's modeling like it may be worth it. The dual 2 ohm VC's means a lot of power for you in the end..... I think for a single sub these are your best bets in your price range....
Make your budget around $350 and buy a QUALITY amp man....
