Push/Pull Box design

[PollyCranopolis 10+ year member]

Have 2 PG Titanium 15's in a sealed 1.5 cf per sub box. Was going to build a ported box for both of them, but theres no way in hell it's going to fit into the trunk of my 92 civic LX. Buddy suggested I build a box, loading the subs in a "Push/Pull" configuration, suggesting that with this setup, the subs would in essence think they are actually mounted in a box twice their size, meaning I might actually be able to fit them in a ported box in the back. Anyone ever built this type of enclosure, or have any suggestions on finding blueprints? Thanx!

Yeh its called isobaric compound what happens is you wire one in phase and one out each sub faceing echother this cuts your box size in half and you only have to cut one hole for the subs
