I've only had the headunit for a couple months. I bought it new from cruthfield.

I have not. I don't have access to a computer at the moment.

I'm using cruthfield brand 4 ch rca cables, they seem pretty high quality, also, does the same thing with a different pair of rcas ran outside the car. I've pulled it out almost every time I've messed with it, moved it around, moved the wires around. No change.

I hope you have their cheap cables, which are shielded. There is a tendency with RCAs to go unshielded with their higher end cables, which of course is bad juju.

I'd try some shielded RCAs and ground loop isolator.

I second the ground loop isolator, they're cheap and easy as it comes to install.

these are the rcas I'm using from them. I don't see why they wouldn't be shielded.

does a ground loop isolator just go on the Amos ground wire, or is it more to it than that?

The description doesn't say they're shielded. The description of the lower end cables says they're shielded. Here's a little info on why shielded is superior to unshielded.

so I'd need a 4 channel, but to be clear, it just goes between the rca ends and the amp rca ports, correct?

Just put it on the rca cables at the amp. If it's a 4 channel amp use two of them, one for the front left and right, one for the rear left and right.

Goes between the HU and amp. You'll need 2 of them.

just exchanged the stereo for another unit after checking everything. I still have the same issue. What else do you think it could be? If I'm using an external amp, I can just use the power and ground in the stereos harness right? to hopefully eliminate some interference.
