Reducing box volume?

[ARK_SWAMP_RIDER 10+ year member]

I'm replacing the stock sub in my vehicle with a JL Audio 8w1v2, and will power it with a JL amp. My enclosure (fabbed to fit the vehicle, already made) is .6 cu. ft. The sub calls for .375. I'm limited on mounting depth, so this is the best I can do as for the sub. Is there a way to effectively reduce the enclosure (sealed) volume, or should I just leave it be?

Sub displacement?

Sub displacement is 0.02 cu. ft.

You won't hear much of a difference. It wouldn't be worth the hassle to be honest. It should sound amazing either way.

I'd see how it sounds and then you could always throw in a couple pieces of wood. MDF, 2x4s, whatever.

Or non hardening clay on the bottom or the enclosure.
