2x8W at 4 Ohm TPA3110 Class-D Audio Amplifier Board
The TI datasheets lists this as an 15W/ch amp in 8 ohm. But here it is listed differently. Is it toned down? Thanks.
Can I power this amp with a 12v, 6800 mAh battery?
Yes that will work fine with this amp.

I soldered my board up yesterday. Unfortunately, when I hooked it up to my Acoustat preamp and Tekton OB4.5 speakers, I get a constant "thump" from the speakers and the music that's there is very, very low. Any thoughts?

I'm confused by "board only" in the description. Is it just the circuit board and I have to purchase all the little bits that it shows in the picture separately or is it all there and working, I just need to add an on/off, power and volume?
"Board only" simply means this is not installed in a casing. You will receive what is pictured, which is a fully functional amplifier board, completely assembled with all required parts, just not in an aesthetic case.

Which potentiometer would be adequate for this board? I see several on you site but not sure which one would be best? 5k, 10k, etc..? https://www.parts-express.com/Search.aspx?keyword=potentiometer%20stereo&sitesearch=true
found the answer, 50k per the manual.
