So is it safe to assume that most 12" subs will want 1 cubic feet volume?

Since I am a little small can I make up the rest with poly fill in the box?

No i have a 12 inch subwoofer and it calls for over one cubic foot of volume, although it is a high performance MBquart woofer...

Is there a list anywhere that gives ideal box volume for 12" and 10" subwoofers?

I have a 99 Silverado extended cab and I'd like to make a box to go under the rear seat on the driver's side.

Thanks, Tom

Measure twice, hate yourself once.

every sub is different.
If you build a 1 cu ft sealed enclosure than find a sub that will perform well in sealed enclosures.
There is NO ONE SIZE FITS ALL

1 cu ft + a 12" subwoofer...sealed is the only option you have.
1 cu ft is barely enough for a ported 10" sub. Shove a 12 in there and expect dog ass sound

I did some digging with our suppliers *I'm from a site Stompaudio.com * I'm here to help you guys not spam so don't freak out.
As i said I was doing some digging and came up with, Pioneer Low end subwoofers are capable of performing under low CF levels, down to 1CF.
Personal experience tells me the Fosgate P1 is great for 1CF as this was my first system years ago. As well as experience they are actually made for small air tight enclosures with less Cubic Volume than other subwoofers might need to produce the same sound level.

1 cu ft is not enough for a ported enclosure for pretty much 99 percent of 12 inch subwoofers
Only ones I know are the TC Sounds drivers.

Agreed unless they are shallow mount and specify.
Your sound will be garbage and it will probably damage the woofer body.
you Might be able to make up for the lack of an AIR cushion by making a smaller port but tuning is going to be near impossible.

A subwoofers mounting depth has nothing to do with its enclosure size.
Shallow mount subwoofers can require even larger enclosures than normal subwoofers
