This is not a "want to buy" thread. I am only sharing my opinions on amps for a $300 budget.
I am not the world's foremost amp expert. But I have owned and tested my fair share. I am also cheap. I don't like spending more than $300 for an amp either so that's my wheelhouse.
This is my list, in order, if I only had $300 and was looking for a sub amp. It is subject to change at any time and I am open to other suggestions if I am leaving one out or you don't like my rankings. But if you suggest a crap amp, it ain't making the 1st page.
My list. In order. For a $300 budget. Take it FWIW.
I am adding an amp to the far and away #1 here even though it's ~ $60 over budget at $360. The SoundStream DTR 3400
. If you have $300, dig around in the couch cushions and find another 60 bucks.

9 - Used Crunch GP Pro 3k

Noteables (and only because they're discontinued, hard to find or not always priced at or under $300)...
- MBQuart Discus
- Used Atomic or RD stuff (1600, 1750, etc)
- IA 20.1 (if you see one for $300, snatch it)
- Kicker 1500 (solid 2 ohm amp. expensive and not very versatile, IMO)
- Rockford Fosgate t1500
Falling from the list is the Crescendo BC2k. Still a good amp. Not in favor of the price increase though.
Added - Skar 1500
