21in IA DP Box plans

Recommended Posts

How does this look for a box plan. I am looking at going ahead and buying a 21in DP since I have plenty of airspace to work with. I also wanted as much cone area as possible that would be ok powered by my Saz-1500v.2.

This would replace the rear seats in my 07 F250 and would be at window line. Goal is to hammer the lows, get loud as piss and sound good doing it.

Will this work or should I change anything.

Sub / Port will be facing forward.

Around 10cu tuned at 30hz

I got no responses in the IA section so it may be better suited here.

That looks like a pretty good design. It should slam the lows, 30 hz is a great tuning.

I would build it, just throw some bracing in there or you'll have box flex.

This is a lot of airspace and alot of port area, just want to do this right. My current setup has sub forward port to the driver sound and it slams. But with this the port would be right behind my seat, not sure how that will sound.
