How do I set up speaker wire to switch inputs between 2 receivers?

Q. I have a 5.1 Sony home theater and 2 Paradigm Titan V.4 monitors on a Denon DRA-397. I use the stereo for my computer and the surround sound for TV/games. In my new apartment, I have my computer desk sitting in the back of my TV room and I'm looking for a configuration in which I would only have to mount the Paradigms on the wall. They sound much nicer than the surrounds that came with the Sony set. I want to be able to switch their input back and forth between the surround channels out of my home theater receiver and the L/R channels on my stereo receiver. I'm pretty sure it's not as simple as fastening both sets of wire into the speakers and I don't want to ruin any of my equipment. How would I make this doable? Does my Sony receiver outputting 100 watts per channel and my Denon outputting 80 watts per channel change anything? This would be a really nice setup to have instead of having to put up a shelf for the Paradigms AND mount up the surrounds for the Sony. Thanks.

A. You can't set up speaker wire to switch inputs to receivers. Your question is confusing, because is sounds like you have an audiophile grade stereo amp and speakers (perfect setup for music) and a home theater receiver driving a full set of 5.1 speakers. If you want the stereo to join in on the theater fun, take line level signal from the sony wherever you can get it (line out left & right, headphone jack, etc.) and pipe it into the denon. This corrupts the surround a bit, as the stereo downmix will have all audio coming from just left and right. If you want the sony to jump in on the music action, line level again. If you had one set of speakers and wanted to easily switch amplifier/receivers that drives them, you would get a "double pull, double throw" switch rated for 5 amps (or more) for each set of 2 speakers you want to switch. The switch(es) have 6 contacts. The center 2 are the "pull", but we're going to make them the "throw". Connect these separately to the positive terminal on the speakers. The other contacts (2 on either side of the ones we just soldered) get connected to the positive speaker terminals respectively. Run the negatives directly to the speakers from both amps, using the same length as the sum of both sides of the switch on the positive. This will disconnect one amp while connecting the other. If this doesn't at least send you in the right direction, I've just wasted a lot of oxygen. Good luck!
