I'd rewire the harness to avoid doing the connections you just mentioned. The less RCA-plug connections, the better. By rewiring, I'd have only one: the external used to connect the final piece of interconnect to the rest of your stereo system.

If we're speaking completely ideal situations, then I'd love to grab an extra harness connector and pins and make my own soldered connections. Then I wouldn't have to touch the current one at all, and I would be left with far fewer wires inside my case.

I'll be using RCA connectors that thread to the chassis as well. I didn't see these at Radio Shack on the weekend, but I know some of the electronics places around here have them.
