Do not read.

got it, question what kind of wall did you have before, and what kind of wall are you about to do on the rebuild? I was thinking of doing a 6th order. If I cant get any help on how to build one because I know they are pretty complicated, then ill just do a standard slot port.

Cut my wall out last week. New wall getting built Monday. Use .75" 11ply birch doubled or tripled walled and braced.

Had a cpillar flat wall. 22cubes with 270" of port.. New wall is going to be as big as can be with prly 300" of port.. U would need a bpillar wall if u want to do a 6th order. Takes a lot of room. The ported side the subs are in tune lower to like 28hz and then the front chamber is tuned to like 48hz for a starting point. Make interchangeable ports so u can adjust it and find it's sweet spot because 6th takes a lot to get right.

 
yeah that's the thing, 6th orders need to be big. I wanna keep my rear seats, so maybe a slot port design would be best for me. do a build log of that if you have the chance id like to get some ideas. how was driving on the road with that wall blocking your rear view? that what makes me think twice about getting a wall, a constant blind spot
