I'm recently installed a pair of Kicker KS component speakers in my doors. The midrange is located in the stock speaker location, the tweeter is flush mounted into the sail panel, and the crossover is located behind the kick panels. With the volume at Zero and the headlights on, I am getting a buzzing sound in the drivers side tweeter. This only happens with the headlights on. Any ideas on what is causing this and how to prevent it?
