Quad box for DD 9512s

[Nick607ny]

Trying to build a sub up port forward quad box for DD 9512s. Trying to tune to 36ish. Any recommendations? It's in a 99 escalade and I'm looking for more sq then spl but need heavy bass because I have some very loud highs and mids.

You will want to fire the port towards the rear hatch of the vehicle so it has something to load off of and makes the wave longer and a lot louder.

Was trying to go w a lay down wall kinda idea but can always rotate it. I've built a couple 9f boxes before. Just new to digital designs 9512s.
