Howdy, We just bought our first Mustang (05 GT Premium) and it came with the Shaker 1000 upgrade. We have two issues being worked at the dealer and if you've ran across these issues, please post a reply.
- The stereo will not stay at a constant volume. We've turned off the "speed volume" but this hasn't fixed the issue.
- Something is draining the battery. If the car sits two days, the battery is pretty much dead.
For those of you interested in the Shaker 1000 upgrade, let me pass on a little information to help with your decision. THIS INFORMATION WAS TOLD TO US FROM THE FORD MECHANIC: It takes 45 minutes to diagnose each amp, there are six amps total, and the diagnostic test must run consecutively, in a specific pattern. Each issue with this stereo requires the mechanic to re-start the diagnostic test, which means about 6 hours in the shop for the car owner........ Yesterday the diagnostic test wouldn't go past #3 amp, which required him to restart the diagnostic test two times..
Ford has required our Ford dealership to send in the defective part(s), and they will fix and return them. It took three weeks to get the first two amps repaired (actually Ford said they would repair them, but ended up just sending back new amps). I wonder if it's that hard to keep extra parts on stock at Ford.
This is my first Ford Vehicle, but the rental they have us in right now has a better sounding stereo than our $1,300 upgraded stereo (a stock Chevy Malibu stock stereo).
