I have a 2003 Ford Escape. I want to build a wall for 4 kicker solo x 12's. I can do all the wood work no problem, But I know nothing on where to start and so on. What I need is for some one to figure out all outer measurements for all 4 walls and for the port size and length. Basically I need all measurements, I can do the wood work myself. I want the design to be a standard square wall with 2 subs across the top and 2 across the bottom with the ports in the middle of the wall from top to bottom. Pm me with what you come up with. Thanks.
