I do hope you are able to come to an acceptable solution. I use a REL B1, one unit, and it blends beautifully with my Sf Cremona Auditor Ms. A true sw should be felt before being heard, part of the room pressurization they are designed to do.

Sometimes there are connection issues with REL when connected to fully balanced, or dual differential amps. The issue is finding the correct place to ground the sub. Try connecting the blk. wire to chassis gnd. or to the gnd. side of your amp's RCA input. If these two locations don't fix the issue leave the blk. wire disconnected and run a separate wire from your amp's RCA gnd. to the sub's RCA input gnd. .

For REL setup experts
Buck - not all McIntosh amps have the same output configuration. Your 402 like my 602 has fully floating transformer outputs that aren’t referenced to chassis ground anywhere.
So the REL speaker level hookup just doesn’t work in this case. It’s a REL design defect. REL needs to use balanced differential inputs for their speaker level connections which would solve the problem completely and simplify user hookup. Other sub manufacturers do exactly this. You’ve found a pretty high class way around the problem! Tom

I'm not familiar with the grounding scheme of your new amp. Hope I wasn't too technical, simply put grounding is the key to proper operation. Some amps, like my Levinson, have two ground circuits, chassis gnd. and signal gnd.. Signal gnd. is 10 ohms above (higher) chassis to prevent noise from degrading the input signal. So I had similar issues. This is not a defect, just requires a different solution.
