new box design help???

im gonna build a new box strictly for spl and was wanting some input! its for the same 4 re sx 10's in the 2006 jeep grand cherokee off a cactus pf600.1 at .25 before rise. i have as many as 6 4" aeros that i can use for this was thinking roughly 4 cu. ft. total after displacement. the main question is subs up and port back or to the passenger side? as long as the box is no more 30" on one side i should be able to just rotate it to test between back and side firing but any input would be helpful. thanks!

also box will be tuned to 54 hz my thought is 4 cu. with 5 4" aeros tuned to 54 hz idk what the dimensions will be since cant decide between side or rear firing. thanks

My latest design is 24x14x15 (~1.9 after displacement) with 3-4" external aeros. 2 mid-grade 10's and 2kW from the trunk... so you'll probably be similar (only doubled)

If it were me, I'd build a bass cube. Make a 24x24x18 box. That's ~4 after bracing and woofer/port displacement. Cut a crap ton of 4" PVC to tune 48, 50, 52, and 54 Then, spin the enclosure to let the port face back/left/right/front. Find the maximum SPL. Just so you know, I've been reading that port to the driver's side is usually louder from the trunk of SUV's.

yeah i was thinking something like that but it has to be under 15" tall because that is my window line. i was thinking something like 26x26x15 with double baffle subs up with 4-5 4" aeros my calculator keeps sayin i only need 4 4" aeros dont know if that extra 1 is gonna help or hurt!!

yeah, from the word on the street, aeros require 8 sq in/cf of box.

That's 32 sq in of port, or 2.5-4" aeros. So strictly speaking, you'll need 3, but since you're doing small box, lots of power, 4 is probably a better bet.

For a 15" window line, your 26x26x15 sounds perfect. Be sure to take pics of the build/testing.

thanks i will!!
