How do you fix audio fuse in ford expedition that keeps blowing out?

Answer 1

I own a 2001 Ford Expedition EB with Mach sound system. I found the answer to this question via another message board. The problem is a bad amplifier that powers the subwoofer. As long as the amplifier is connected the fuse will continue to blow. To fix this, I removed the cup holder by the back passenger vent window with a flathead screwdriver and disconnected the power to the amplifier(silver metal box) which solved the problem but left me with no bass. I was able to find a brand new replacement amp on eBay for $85 including shipping. Just search "expedition amplifier". The model # of the amp is located on the sticker on the bottom of the amp. To remove the amp completely, you also need to remove the snap in cover over the subwoofer (rear passenger side). This gives you access to two of the screws holding the amplifier in. You are going to need a small torque wrench with a 9/32 inch bit to remove them. The screw(s) on the other side will be a bit trickier to remove. Removing the screw on the left will require reaching through the opening left by the cup holder and removing them with the torque wrench. The shorter the torque wrench the better as it will give you more room to maneuver. Once the screws are removed the amplifier can be taken out by gently flexing back the rear panel and squeezing it through the subwoofer opening.
