Is this normal or is there something I need to look at more seriously? My guess are some grounding points but I'm not even sure where to start. Any leads appreciated. Thanks!

You have interference from a ground loop. You can buy loop isolators for headphone and RCA jacks online. They are not perfect but work well. Otherwise you need to ground your audio system directly to the battery.
