I found the source of all my noise is in my RCA cables running to the (first) amp, an Infinity 7541a. I also found that if a get a small jumper wire to connect the two outer jackets of the RCA connectors at the amp input, thereby making a common ground, all the noise is eliminated. Is there some sort of device that can I can use as a permanent solution? I've also seen RCA's with a separate ground wire at the end... is that what this wire is for? Though I'd hate to replace on otherwise good set of cables.
