Tpa 3116 sub board.

Hi!
I got some of these boards from old subwoofers.
They got bt boards solders on..
Is it possible to remove the bt board and connect a aux cable directly?
The idea is to use them in a new build.
I have two different boards..
First photo is with bt mounted on top, second board has bt on back..

Should be, since the bt boards seem to be separate. After you remove them, you need to see what the bt chip is, find it's data sheet and with that you may be able to figure out the board schematics and pins for the board itself.
