Yet another engine noise post

I've got a Nissan Murano with a HU that cannot be replaced(pic below) so I have a pac unit(ROEM-NIS2, didn't have to cut or tap wires, plugged into stock HU) and I have had engine noise for the longest. I have check and moved my amp grounds to no availe. I know that my grounds are good. Should I just go with the ground loops or something else?

try moving the rca's to a different side? Maybe move the factory HU ground?

RCAs are on the opposite side of the power wire. Haven't tried the HU ground since its factory wires.

But are the RCAs going past the fuel pump or anything else that can cause extreme interference? Are they shielded or twisted pair?

No they are not near the fuel pump, going down the passenger side and they are shielded RCAs.

I'd suggest redoing the factory HU ground.

You might try connecting your amp remote wire to something different. I had noise and couldn't find it. It ended up being my remote connection.
