My Jeep is louder firing into the corner or side over firing back.

OP, Robert's Explorer does very well ported to the passenger side

See I have 2 18's firing rear and my hatch is not doing well. Maybe in the future I can do this in my 03.

Robert is ported to the drivers side isnt he the box is on passengers side I thought. Here are a couple pics of the box I started today 10.6 cubes tuned at 45hz I even 45'd the corners.

brace that as best as possible. double up that port wall or throw a 1" dowel between the the port and side. good luck at finals- this friggin arm of mine screwed my whole season up.

Yeah double layer though bottom inside is that the outside is regular birch plywood.
