Can you run a subwoofer on multiple systems?

Wondering if it would be wise to run one subwoofer on two different systems in the same room. I am running two separate subwoofers now, but want to downsize things and do not run both systems at one time. So basically wondering if I can run one powered subwoofer through a switch selector for two different set ups.

set up one is a Mac 2105 with a Manley shrimp preamp (main system)
set up two is a audio engine A5 computer set up going through a Arcam Dac.

Thanks
