Can these be used for both Plasma and 2-channel??

I have a pair of Silverline Audio (Sonatina II's) that
I've been using for my living room 2-channel setup with
very acceptable results.
I just purchased a plasma TV without speakers. I disconnected the speakers from my 2-channel amp and ran
a pair of good 16ga speaker cables from the TV to the Sonatinas. The TV sounds great.
Here's my question. Is there a way I can use these speakers
for both my plasma and my 2-channel setup without disconnecting one source and connecting the other?

Thanks in advance for any information!
