may03LT Posted February 1, 2011 Report Share Posted February 1, 2011 I squeezed 18's into mine, 11-ish cubes at 36hz. 33 should move some air. Link to comment Share on other sites More sharing options...
Symmetry9898 Posted February 3, 2011 Report Share Posted February 3, 2011 i had 1 18 in the back of a trailblazer and i was runnin out of space fast as they take up alot of space. Although i am no expert and have horrible box building ability i have seen it done. There was a guy on here that made a bad ass box in a trailblazer ss with 2 18 inch btl's in it, looked solid. 33hz is gonna be fun but its also gonna tear that trailblazer up. i would recommend deadening the roof before you install anything cuz that shit is going to flex.
