Review on 🔌 Scosche FDK11B: Perfect Wire Harness for Select 2003-08 Ford Premium Sound & Audiophile Systems by Rod Evans

Main Wire Assembly works well and deserves a five star rating. But on a 2004 Ford Expedition with CD changer and subwoofer, the subwoofer cable is not properly connected. It's good that I know what I'm doing and checked the cables before installation. I had to change the position of four wires (only two were in the right place). This is another good example of a Revain listed product with incomplete description and compatibility. I assumed "2003 - Up Select Ford" included my car. Note that the standard remote voltage supplied to the subwoofer amplifier is 6V while most main units supply 12V. I don't know what problems applying 12V to the amp will cause. You may need a voltage regulator.
