I've looked back through my posts but can't find who sent me link to buy this amp board, so I have it , came w/o any instructions and two of the connections are only marked in Chinese. Any help on how to use this as  a CBG amp would be appreciated!

here is where it came from> http://www.ebay.com/itm/131832286247?_trksid=p2057872.m2749.l2649&a...

I THINK that those are just left and right speaker connections, the one for power is marked as 12V. (and shows in the other picture attached) Can I just connect both to one speaker or would it be best to use 2 speakers? The info from the page says to use 2 speakers but just wondering.

here is what the ebay page shows for specs> Features:
This is a 12V single power supply TDA7297 amplifier board B board, AC / DC, 2.0 / dual channel / stereo,12V/2A when using, the output power of 15W +15 W, peak up 25W +25 W, can be accessed by two 4-8Ω10-50W speakers, a large volume of small size, high signal to noise ratio.Upgraded version of the radiator, wider and thicker, better cooling effect

I think I just answered my own questions , but please correct me if I'm wrong. 

100% Brand New and High Quality!
Size(LxWxH): 50x40x42 mm
Working voltage: DC 9-15V
Power: 15W +15 W
Maximum power:30W+30W
Output Impedance: 4-8Ω

AWesome thanks for the tips!

AND, do you think that something like this would be a good match?>

this is from the auction you linked.

a guitar is not going to drive this without a preamp.it is designed for a mp3 player that has bigger output than a guitar.it an AUX input. you will need something with 20db gain as the preamp . 

those speakers should be fine. bigger as in size not wattage is always better but will depend on the box you are going to put it in.

OH thank  you! Did not even think about the input not being the right level.  Do you think the preamps Gitty sells would work as I already have one of those mounted in a box?        

in a word ....yes... 

leave them in separate boxes that way you could still use this amp as a amp for your phone... or  pop them in the same box . your choice.. 

Interesting puzzle, I went looking and found translate.naver.com which lets you draw with the mouse, the Chinese characters and help you translate.

the characters in the first picture for the +/- connector by itself translate to Right (with the) channels

the characters in the attached picture for the +/- connector next to the labeled 12v connector translates to Left (with the) channels

and judging from the relative sizes, the input looks like a stereo aux cable jack for cd/mp3/tablet/phone. 

suggestions...for a git amp, connect both tip and ring on the board to the tip on the git jack to play out both channels, or connect tip on the board to tip of git jack #1 and connect ring to a second jack which would let you jam with a friend or plug in a player to play along with...

Thanks for the ideas JL, did not think about needing to go from stereo to mono.

as JL said just bridge the L and R together and use a mono input jack , or you could just have two input jacks as this has enough power... one for git one for a mic... but that way you will need either two preamps or a stereo preamp...
