Do the subs as a down fire.

I think this is a very good idea.

ok, I might actually give it shot then. Should i still fire port toward the rear though

Wouldnt facing the seats act like a loading wall too?

yeah but then then i will lose pressure because it will travel in the opposite direction of the cabin. That might work if I completely sealed off the trunk and folded the seats down though

I honestly never drove that far in my personel vehicle. I have been to fort greely many times for training and only driven there in military convoy which travels 35MPH

If I had to guess though it might be only 1.5 - 2hrs depending on the road conditions

i had two 1508s in my sisters vw bug without a loading wall but the rear hatch was not far so i didnt think it would be necessary. my pair was seeing about 1500 wattss

You will lose output.

heard it in person, sealed 3 cube box firing at a hatch. Switched it up to downfiring 3 cubes and it was muddy and not very loud.

We currently have 3 setups with loading walls.

1 2 X 2510's .5 on a M2 in a Hatch Mustang, Port is to the side, loading wall is open to the top, sounds awsome, guy plays rock and loves it. makes the top of the car ripple.

2 2 X 1508's .5 on an Opti 2000. Same box as the stang, Does a burp at 145.7

3 1 X 2512 2 ohm on a PA a1000db, port is to the side, slot to the front of car in a 300m, Guy listens to older rap and hip hop, he come back after two weeks to tell us how much he loved it.

Done right they still sound great.

Your welcome.

PS, Nice thing about the box is you can always build another if you dont like the first.

MDF is rather expensive here in fairbanks, Alaska and @ $60 bucks a sheet of 3/4 MDF, I'd rather get it right the first time

i wonder if my setup in my single cab truck is acting like a "loading wall"...(2 Kicker Comp 12's in 2.2cuft sealed off of a Crunch 1000wt amp) each sub behind a bucket seat...it is umbelievably loud.....as a matter of fact we sat a 15" CVX in my passenger seat and hooked it up to my amp.........even though it was in a prefab ported box, and probably underpowered....it wasn't any competition for my

comps..."they blew the cvx out of the water"
