Default DIY 2.1 channel class d amp?

Using two PAM8403 class d IC, is it possible to create a 2.1 channel amp?
What I got in mind is having a stereo to mono mixer at the input running parallel to the amp, and driving the output of it to the second PAM8403 amp and feeding it to the sub. Is it feasible?

Or you know of any 2.1 channel amp, 5 to 10 W?

Two PAM8403's, one fullrange or highpassed, one lowpassed will work great.
You could also go for something like this: 5V USB 2 1 Channel Digital Audio Stereo Power Amplifier Board Module 5W 3W | eBay
