Hello, I have just setup an HD projector in my patio and I must admit its quite a bad ass outdoor theater. Now the thing is that my outdoor speakers are setup for parties ( 3 250 watt amps looped mono connected to an ipod dock). Now I have a 5.1 receiver I want to hook up to the same speakers or at least 5 of them that are set up perfectly around my projector screen for surround sound. I want to switch between the two amp set up depending on wether its a movie night or a party night with the three hard cranking amps Is there a selector r selectors I can setup to swap between the two. Please help.
