First off why laugh at the reputable mans face (must not like support)
second do ya have a relay for your remote turn on? If not try one but use a diode across pin 85 and 86 with tha cathode goin towards the remote lead from the head unit and chassis ground your amps unless they are really close to your battery
And dont laugh at the guy who knows what he's doin when he's tryin to help ya that'll never help

So correct me if I'm wrong.
With the RCAs unplugged everything is great - at all times - no noise right?
From that point of view I would say the issue is not with the amp.
So start tracing the problem back from there.
1. Try a different pair of RCA's. If the problem persists
2. Try a different source unit. If the problem persists
3. Examine your connections at the deck harness for crappy grounds etc.
One last question which I haven't seen asked yet.
What is your amp remote line connected to? Is it connected to the Deck or the car's ACC line? If it is connected to the ACC line that would account for pop because the amp is turning on before receiving audio signal and turning off after audio signal disappears from the deck.
A side note:
Why is your amp mounted to the roof? Amplifier have heat sinks and are desinged with the recognition that heat rises. Mounting the amp upside down on the roof ignores this design and causes the heat to build up inside the amp without a proper place to dissapate. Without adaquate relief from heat, all of the internal components are much more prone to overheating and premature burn-out.
Based on that, I would like to make a friendly suggestion for you to mount your amp on a different surface.

Alright, I'll try to answer as many of those questions as I can.
The amp is connected to the remote on the amp. Like I said before, the pop was solved by grounding the RCAs. I mounted the amp on my roof as there's not a lot of room in back anymore. And I dont feel like making another amp rack at the moment. It doesnt heat up to bad as the gain is right down, and I'm running the amplifier WAY below potential. I'm considering running the sub at 8 ohms insetead of 2 to see if that makes a difference with the noise.

I used the same RCAs on this install as before and I never had this problem before. Would a ground loop isolator help this? I have a lot of power wires near rca's in the back (unlike before) and I'm assuming that has something to do with it.
