Diamond Audio Amp Schematics
So I think I have it right, but speaker output for the micro 2v2 4 ohm front channel. Is it left top= right negative and left bottom = right positive?
Right top = left positive and right bottom = left negative?
I am not bridging.

What year bike?
Where do you have it power and grounded to?
Stock radio?
Where is remote turn on connected to? Accessory? DC turn on?
High or low level input into amp?

Iron Cross RCA upgrade to a 2006 Street Glide (original owner).
Popping when I tap the RCA cables. Fire up the bike and louder and more prevalent popping. This is with a CD for source
Talked with the online company (not sure I can say names) I bought the amp from and they think it is the RCA circuit board that is the problem.
Anyway, the bike is totally rewired and many hours of frustration. We will see if the new amp works out.

That amp will also take speaker inputs (high-level). You could just tap into the speaker outputs on the HU and bypass the Iron Cross pre-amp output to confirm if the issue is in the HU and if it's related to the pre-amp output. Make sure to redo your gains from scratch if you do try this.

I think if it was a poor ground you'd more likely get hum or whine. Popping (especially when tapping the cables/connectors) sounds more like a bad or intermittent connection. OP could try swapping cables but it sounds like the HU to me as swapping the amp didn't resolve the issue.
