I'm not sure I totally understand how to try your suggestion with rca sockets and plugs. Do you have a video or image demonstration?

Simply take an RCA plug and socket and solder a wire from the centre pin on each to the other - don't do anything with the earth connections.
Make two of these.
Now unplug the RCA cable from the amp's input, insert the RCA plugs (you just made) into the amp's inputs and then plug the RCA cables (from the HU) into the sockets.
You now have a signal path from HU to amp (for left and right channels) but the RCA cables are ONLY earthed at the HU end (not at the amp end).
Might help...
