4 RE SX 10 D2'S BOX BUILD

[resx's]

Hey ive got 4 RE SX 10 dual 2's and im looking to design a new box for them. I have a 93' Buick Lesabre. They are currently in a ported box with 4 4" aeroports firing to the rear subs firing up. the box is around 4 cubic feet total with a divider in the middle though. What does everyone reccomend? ill get trunk specs later after work. Currently only playing off of power acoustik 6000.1D but will eventually be powered off 4krms
