Ah! Sorry again! I really appreciate your help! I'm assuming those measurements would be with the feet, I did measure it myself standing on it's back. I don't have the enclosure here to measure right now and it's literally -48 outside right now so I don't want to venture out!

The amp I'll be using is this Dayton Audio one:Dayton Audio SA230 230W Subwoofer Amplifier - Audio Amplifiers - Audio / Video

A link! I run a 15" Dayton subwoofer with that amp and it's great. I believe it's 4ohms.

Subs - 12", please give a look at this other thread where there are various drivers, so we can be more specific later with one that is adequate for you.
I assume your enclosure has a port ??? Dimensions? (Sometimes it can be changed later, and in your case is an open question.)
High quality small PR sub design?

A box shape that has dimensions 20 inches by 15 inches by 17 inches has a volume of:
If external don't forget to mention the thickness of the ply as was previous said.
Let's assume it's for internal dimensions: 2.95ft³ = 83.535L
Now taking about 2/3L for a driver we get about ~80L for a sealed driver enclosure, ~70/75L for a ported driver enclosure.
In the case of the sealed or ported check clearances, diameter, for this drivers as a starting point.
The downside for this project is that you might have to change your speaker dimensions or build a new sub enclosure, what always works best.
