Review on Hiletgo 3pcs PAM8610 215W Digital Dual Channel Stereo Audio Amplifier Board AMP Class D 12V: Powerful and Efficient Audio Amplification Solution by Keisha Stewart

Great for small projects and easy to use. Great because most of them only specify 12V while this one allows 9-16V. The only negative is that mine came in two places without a screen print. Stick it with the L/R input on top, left output on the left and right output on the right, bottom pads unmarked. I found a board with the same layout and components on it. If this happens to you, the bottom left pads are 12V on the left, and then ground on the inside. The right pads are labeled "Switch" I assume they toggle it on and off. (See attached photo)
