Question about Rockford Fosgate Car Audio & Video
It sounds like you picking up noise from the inverter itself. There's a transformer on the output that changes direction 60 times a second to produce the AC. A signal will radiate a short distance from the inverter and is being induced into the other wiring. I'd try plugging the inverter into another outlet in the vehicle (perhaps in the back) and maybe install a "Rube Goldberg" shield. Likewise, use a shielded cable from the laptop to the AUX input and put a "ferrite bead" on the output end. Use a large bead and wrap the cable one turn through the center.
Hope this helps.

Another solution is to try running a ground strap to the case of the inverter, or by a cigarette lighter adapter/charger for your laptop. Bypass the inverter. I have a adapter for my acer. ( 12v to 19v adapter made specifically for acer)
