and wire up two solid state DPDT relays inside. I have all of the parts minus the project box.
I'm not sure what you mean by "solid state" relay. If you mean a relay without any mechanical contacts, this is a bad idea for audio because there is a little "glitch" as the signal passes through zero. This is not an issue for most lamps and motors, but it will tear up the audio.
