Has anyone done a measurement of the the impreza spare tire area so it can be used as a sub enclosure (in fiberglass of course)? From eyeballing it it looks to be about 2 cu. ft. or so. I've seen the enclosure another member has done keeping the spare, but I am interested in using the whole space. If no one has anything, I guess I'll lug bottles of water downstairs and fill it up

 

try using packing peanuts. Thats what I use

 

Good idea, but I have a garden hose and no peanuts at home

No big deal, I'd have to clean it out anyway.

 

I also added water to my finished fiberglass enclosure that I constructed. It's still sitting there unused since I bought pre-fabricated enclosures for my car. Anyway, I forgot what the volume was, but it's not very large at all -- definitely (way) less than .7ft^3 of space.

 

Just finished testing this.

The spare tire well in the STI holds an amazing 60 quarts of water.

That is almost exactly 2 cubic feet of space. Even removing a small amount for fiberglass and the area the speaker occupies, you are still looking at around 1.7 cubic feet. Not bad!

 

if you guys know some calculas you could do it using integrals to find the volume

 

you really shouldn't need calculus to calculate the volume. i can't remeber exactly how it's shaped but isn't it basically a half circle on top of a square a few inches deep? it is slightly inclined on the edges so you can just measure your widths at the halfway point. should be pretty accurate. i'll check tonight.
