SEE IM STUCK AT THAT! 4TH OR 6TH ! Lol 6th wuld be more work and more tuning/tweeking but might end up being worth it.. 4th order are fairly simple but still are good .. idk its a toss

for 4th order, make the sealed part 2.0-2.5 cubes per sub. then use the port to adjust the fq... mine in my truck is about 16 cubes sealed (for 8 15" subs) and around 35(ish) cubes ported. it peakes around 41 hz, but it has to go through the back window of my truck... LOVES the lows to low-mids
