thanks for the reply....
What would you suggest?
I have 18"x 40"x 20" to work with.
I'm not going for loud as possible. just so i can use the area behind the seats,not up against the truck.
would a 1:1 ratio 4th bp better choice? or move the rear to 4 cubes and front to 2 cubes for the 6th?
Thanks for any help guys.
