    Hey Duct_tape123 would you recommend using shallow mount woofers with that box?

    I've got a pair of Rockford Fosgate P3s in the upper box. 1.73 cubic feet with just over 5.75" mounting depth. If the sub doesn't have a wide magnet you could squeeze a 6"+ sub in there. The lower box is 1.23 cubic feet with the same mounting depth but it has a 'recessed' area for my Rockford Fosgate Power1000 5 channel amp. If you can run a full depth sub, do it. You will be much happier with the output.
    And thanks for the kind words, guys.

    Looks like I'll have to build the box for the crew cab differently than I usually do. But I already have the design for it =)

    You've seen the design. Normally I do them like you do. This is slightly different.
