Anyone know what chip is inside this thing?

Does anyone know what is inside this little amplifier? Found here A Kinter A7 with bluetooth

I'm pulling the trigger on it anyway beca

use for 11 bucks and all the other goodies it's a cheapie to play around with.
 
It pays to search a little before answering, anything BUT 500mW "PC speakers".

Rated 20W per channel, probably closer to 15W/ch into 4 ohms, fed from stable 12V DC.

Probably a stereo class D bridged output chip, MANY fitting that spec, all sound fine, I´d just connect a couple speakers, some signal source, and enjoy it.

The actual chipamp used is not too important, and again: "all sound the same".

IF still curious, open it and post IC codes, maybe a closeup picture.
