Hey, I want to put a small sub, maybe 8" in my boat. The only problem is the place I can put it only allows for a box with an internal volume of about .25 cu. ft. with a wedge shaped box.
You guys know of any subs with a low Vas, or any ideas that will work with such a small space?
I found a 6" sub that will work, but I'm not too sure if going that small will produce much bass.

if you want you can get one ten inch shallow depth sub like MTX, KICKER or some brand like that and it will fit in the box just fine

I did some re-working and I can probably squeeze about .40 cu. ft. might have to grease to box to get it in place. That should open up my options a little.

The box is going to sit in the channel, underneath the console. It will have to be a wedge shape, and I was thinking about firing the sub toward the front, which would be the back of the lounge type seat in front of the console.
Channel is 12" wide, about 15" deep, and depending on the shape of the box, about 10" to 12" high.

I think part of my problem is reading into the speaker Vas number. I thought that Vas was kind of a reference to the size of the enclosure it should be in. But I've seen 8" subs with Vas up in the 5 to 6 cu. ft. range. That just sounds way too big for an 8.

that most definitely looks like a place you could put a small sub, but where are you going to mount ur amp and cap?

Not really sure if I need a cap, I'm not going to be running huge wattage. Just a single channel amp around 200 watts. If so, I'll probably mount it in the engine compartment next to the battery.
Amp can mount on a panel behind the fire extinguisher. Get's pretty good airflow under there.

see i've never been into marine audio for the small fact that the only boat i have...is a bass boat haha. but how's it go about staying dry and stuff? as for that sub you could most definitely fiberglass a box into there that'll fit and look really really nice. in my opinion thats what i would do because then you'd know it'd fit.
