I have heard that it is best to fire them to the rear
but I was trying to keep my car quite as I could inside. I have dual 3 inch exhaust with an H pipe. The mufflers are 14 inches long and you can see straight through them. I knew I was not putting sound deadening in the trunk or carpet, so I put a thin piece of metal over the back and cut a hole for the sub to fire through. That way I could isolate the trunk from the cabin.
My sub box is very simple. basically a square with an angle to match the angle of the back seat. Mounted my amp to the box.
