Basics of Wall Contruction?

[4x4runner 10+ year member]

I tried searching, but could not find what i was really looking for. What is the basics to building a wall? I have plenty if experience with ported box builds for a variety of subs, but never attempted a wall. I have 1 1/4" mdf sheets to use. Its for a 1995 ford explorer, 2 18" fi btl's , rockford t40001 amp at 2 ohms (3000 rms) . Current box is about 9 cubes tuned to 34hz and hits extremely hard and clean, but doesn't break a 150 on a tl . Thats what i want to accomplish, and from what i read the power and subs should be capable with the right build. Any tips or advice on this?

You do not need a wall to break the 150 mark. Other then that, its all in how you are wanting to build it.

well i still want it tuned low, or maybe 6" aero's to be able to change tuning. I don't knwo how else to break 150 with the space available in the back still tuned low. On average is a wall louder than having a box for same tuning? TAs far as contruction , i was thinking bassically build a ported box for the subs facing foward, then build a solid front panel matching the contour of the vehicle attached to the box and the same in the back. Batts and amp mounted behind the wall. I have an idea on the contruction, just not the cubic feet , port size, and tuning i need for a wall.

Only 3kw for both BTLs? They can take that EACH...

Yes 3k on both. its a rockford t4000 at 2 ohms. maybe a little underrated. its a daily set up

I had my single 18" BTL on 3kw daily...It's on 2.5k right now...

i built as big of a square box as i could possibly fir then put a faceplate on it..

basically what i was thinking, but not sure how many cubes is too many , and the port details

Go with a bigger box if you're only using 3kw for the pair. I bet if you jumped up to 11t^3 you'd gain a db or two.

How much of a difference would there be to get up to 4-5k rms? can probably sell the rockford 4000 and get two aq2200's or something similar. Or for a little more get a warhorse, i have seen them fairly cheap , but would only set it at 5k rms. Problem is subs are dual 2 so cant get 1 ohm on rockford, but there is alot of 1 ohm 2000 rms amps that can be strapped at 2 ohm

Ah, good point.

Since you're doing a wall with the BTLs, 15 cubes should be sufficent. I take it that this is a musical build?

musical loud build. Daily set up. Now is there a huge difference in having the wall behind the rear seats or right behind the front seats. I think i can still get 15 cubes behind the rear seats.
