Would a false wall decrease bass output?

[caseyarndt 10+ year member]

If I had a sub in the trunk in a regular rear firing ported box and I made an amp rack or kind of a false wall which pretty much sealed off the trunk would it decrease the bass output in the cabin?

thanks for any input

if your blocking the way the air enters the cabin the yes you will notice a difference.

Dang well how much room would I have to leave open in order not to notice a difference, I mean like the size of the sub port? a foot gap? or just scrap the idea and find another place to mount them.

still the setup in your sig?, if so just forward fire the sub and port, seal it all off from the trunk then put your amp and subs on a rack behind the box.

O sorry no I had that setup exactly how you said, but now I am considering running a diamond d9 in a 2cuft ported box. I do also have a kicker free air mounted in the rear deck just to use in the winter
