How do I hook up 2 preamps to one amp


I have a NAD preamp that I use for music. I have a Lexicon preamp that I use for Video. The problem is I have 1 five chanel amp that I need to use for both preamps. When I try to use rca splitters/y adapters, my speakers play at a low volume. If I disconnect one preamp, the speakers play louder. What should I do to allow both preamps access to my 5 channel amp and not have humming or low volume.

I have a similar situation with an older Rotel processor and Denon receiver. I was going to try this method but then thought about the sub. I want to listen to 2.1 but also have the sub available to the Denon for movies. Any suggestions?
