[Andyz 0]

Any suggestions I have 2 box one black slot port specs are: 3.6 net after displacement tuned to 32-33 hz 2.5" port width 48 square inch of port area, both box are the same size 20d x 26w x 21h, and the aero box specs are: 4.5 net after displacement tuned to 32-33hz, 3 4" aero port 38 square inch of port area, wanted to put a sp4 v2 15 which would you guys prefer to used, I'll do a dual 12 or 15 on my other upcoming car but for now is single 15"

Which vehicle? I would try them both out to see which you prefer, off of looks I would go for the aero portrd enclosure.

It's for a 2012 Subaru Impreza hatchback I tried both but with a btl neo v3 15 and the slot sound louder but when the low kick in the aero want my car to fall apart but I'm asking because I don't have the sp4 yet but soon it's in making process
