Hello all. I havent posted in a while but have been a member her for a few years.
2008 F150 Lariat that I have had since new. Truck came with the "Audiophile" system with the factory subwoofer. The factory radio died back in March of this year and I replaced it with a very nice Pioneer that has been working wonderfully until yesterday. I took the truck to the dealer to have rear brakes installed and had them wash it was well. When I picked it up the sub woofer had a horrible buzz/hum. The hum does not change when the volume is turned down. If I disconnect the sub woofer, the noise goes away. I have no idea what the dealer could have done to make this happen. Honestly what they did should not have any affect on the radio system.
