2 fosgate T2 12s for an old school s10 extended cab - box help

[manguybro]

new to smd. have 2 fosgate T2 12s for an old school s10 extended cab. cant find much out there on the interwebs about boxes for T2 12s. local shop scoffs at T2s and they are a Rockford dealer saying they cant make em sound right and talk everyone into T1s. they suck. i build boxes but am slow at it and dont have the time or $$ to build a couple boxes to try. going ported for sure. also inverting them so u see the motors from the back windows. have plenty of room to build. can go from floor to rear window line. easily can do 7-8 cubes. rockford says 2 cubes per. im thinking 3 cubes per. thoughts? amp will be american bass vfl 450.1 or 2 fosgate 2 T1500-1bdcp's (1 per). electrical is not an issue. thanks in advance.

If you want to give 3 cubes per sub just do 15s, not only you won't bottom out the subs, it will also be louder
