2.1 amp boards

I'm stepping into a new category, at least for me. Searching the bay, Amazon, etc for a small amp board. Nothing that I have seen so far has any real consistency or decent documentation. Very few reviews and what is available is just as poor.

So what I am looking for may or may not be available yet. Essentially an all in one type device. Dayton has a unit in a case that looks good, but I don't like the idea of buying a complete unit just to toss the case.

Is there a reliable company on eBay, etc that has a decent product out there? I know I'm being a bit vague. I'm tired and probably over thinking lol

I bought this one. It drives that 2way i had at meniscus and tangband 5-1/4" sub quite well. It has L/R volume, sub  crossover , sub volume knobs. Just rca in though. You still need the power supply.

Thanks Mike. That was one of them I looked at. It's cheap enough I might give it a go. 

That new Dayton is tempting, but with a set 180hz cut off, I'm not sure. Might be trying one out though.

I used this one for the Harbingers, I gifted them to my best friend, so I only used it for a few days after I finished the build a few years ago, but I think I remember the crossover point being about 250Hz which is really high, but worked for the build. It sounded good, I'm pretty sure I got a 24v power brick to power it as well, bc I think I had a chat with Neil about it and he recommended it. Sorry for all the vagueness, it's been a few years ago now.

Here's the board:

I used a 12v 5 amp power supply but it can use a 24v i think in the specifications. So maybe i can be a bit better with a more stout psu.
