I put a soundstream 7inch flip feeding a 22inch tview in a 1988 motorhome. Problem im having is when i start the motor the 22inch gets lines but when motors off the tvs fine , ive tried 5 different sets or rcas still does it. only thing i can think is the grounds long cause there no ground up in the fiberglass top. Can anyone help?

Run a good ground and make sure the rca's are not running by something that could induct noise. Make sure the video cable is a good 75 ohm video cable as well.

Is there a power inverter that comes on only when the motor is running?
