Box Design for 4 12's

[DWallace94]

I am planning a sub box for 4 12's to go in my 2006 Cadillac CTS.
I have measured the trunk and have the room for this box but need opinions on the sound quality of the box and some sub recommendations.

terrible configuration for that vehicle... also looks like you have to little port area.

if you must have four and have to fire upwards(even though its a bad idea) try something like this.
