plucky...RE is Kick ass
I have a ported box with 2 RE series 12's (gross volume of the box is 5.1ft^3, its big). If you want the subs, I will sell them to you, pm me if you are interested, the box also, but the shipping would murder you, 3/4mdf is HEAVY.
Also. Just screw the rear fill, put some 6.5" componets in the kickpanels, and forget the 4x6 plates.
