As mentioned in other posts I have 2 of these. How would I wire both to drive single speaker? Or 2 speakers maybe?

You could bridge them.

Will it sound any different if I connect each output to its own speaker? This would be easier as both are already built into complete modules. I could then have mono or stereo input options. Heres the enclosure with 4ohm car speakers currently fed with an LM386 amp(https://uploads.tapatalk-cdn.com/20180508/c3aaa2d05b038ba175c27ccf756426c3.jpg)(https://uploads.tapatalk-cdn.com/20180508/ce16d706a05b587729e8f09c7a67e641.jpg)

Since you have 2 amps and 2 speakers, connect one speaker to each amp.
If you have a stereo program (Stereo MP3 from Phone or Player) connect them to a stereo input jack and use the proper stereo cable; if for mono program (say Guitar, Bass, keyboard, etc.) connect both inputs together to a single input jack.
