Answer
Although there are many things that may be causing this, I would start with your ground wires.  It is very important to run big ground wires to the nearest ground point in the car.  The shorter the ground, the less interference will be heard.  After that, be sure all connections are right and tight.  If all is connected right and good short grounds, and interference continues, a noise filter may be required for the power wires coming from the battery.  Hope this helps, Scott
