o8mustang13 Posted April 13, 2010 Author Report Share Posted April 13, 2010 Is this like a half wall backseat box? yeah pretty much becaseu wher ei live the cops are all a$$ holes and i woudl probably get a ticket if i did a wall beacause it reduces my visibility so the back seat will be gone and the subs will be firing up towards the roof and cant decide which way to shoot the port.
