Speakers connection

I have a total of four amplifiers and one pair of speakers. I was wondering how I can connect these four amplifiers with my speakers permanently so that I can select one of my amplifiers to play easily. Anything similar to speaker selector that I can use? Thanks!
Get a good speaker selector and wire it backward.
How are you going to connect your source?
All I could find are speaker selectors made by Parasound and Niles Audio for one amp and multiple speakers. Maybe if you combined a few of these together it may work. Just a guess. Maybe if you visited a high end audio store and ask where they buy their switching equipment. They have many amps, receivers, and speakers.
