Hi,

I have a very unusual problem with my 2004 Ford Taursus SEL Wagon. It has a Mach Audio system AM/FM Cassette, CD 6 disk changer. When I start the car the radio has no Bass like the AMP is not working. If I tiurn the radio off and on again it's fine. I have had this car at the dealer 7 times and they cannot find the problem. They have replaced the AMP, put in 3 new radios and still have the same problem. This happens on the radio, cd or cassette. It seems to happen more often when its cold outside. It usually happens every third or forth time I start the car and it always comes back on if I turn the radio off and back on. Does anyone have any clues?

 

Could possibly be a bad ground somewhere in the system? That's hard to determine without being there. Wish I could help more.
