Factory Shaker 500 Stereo: This was a learning experience for me, so I thought I'd share it and end with a small question. Note: I bought my 2005 Mustang convertible last Saturday 11/15, so I'm still learning how it operates.
• Problem: stereo volume normal when I’m sitting at a stoplight, but increases wildly as I accelerate, such that my calves are vibrating by the door speakers and my pant legs are getting blown away from those speakers by bass sound waves. I have a convertible, so the problem is concentrated at the door speakers. I initially thought I had a ground problem or that the control system for a relay was malfunctioning. However, a close reading of my owner's manual proved otherwise.
• Menu Button: with CD or Radio on.
• Bass, Treble, F&R, L&R were all at neutral so I left them alone
• Speed Sensitive Volume was maxed out: I used the tuning down-arrow to reduce from 7 to zero. I took the car for a test drive and the problem was eliminated. Yes! I'm no longer hip-hop!
My Question is this:
• Shaker: menu does not have an option to turn off & on. My Owner’s Manual mentions Shaker 1000 has such an option to enhance bass sound, but doesn't mention whether Shaker 500 does. Does Shaker 500 have a Shaker mode? If so, how can I access it to make sure it is off?

I don't believe you can turn off the door shakers in either. The door woofers are just on. The shaker 1000 has an additional woofer in the trunk which is probably what you can turn on or off independent of the rest of the system.

Shaker 1000 has a subwoofer in the trunk. You don't.

I don't understand what you are asking. You found the Speed Sensitive Volume to be too profound, so you adjusted it. The settings worked as designed (hence the different levels) and the issue is resolved. What is it that you want to turn off still?

You can still turn down the bass in the sound menu if it is too much, but for sound quality I have found that turning the bass and treble up, almost to max, and keeping the mid at about the 0 level. but that's just me.

I have an '06 'Vert. I keep my speed volume at 4-5 and it seems fine to me, top up or down.

You answered my question in the first sentence of your answer, regarding the difference between Shaker 500 and Shaker 1000. As you and the other members pointed out: I don't have Shaker in my menu because Shaker 500 does not have the equipment to support it.

To all the members who have answered: this has been a helpful thread. Even without the Speed Sensitive volume on and without Shaker in the system, I think the speakers are too bass biased. I will try turning the bass down next.

Wow, and to think that this info is available in the Owners Manual, too!

Just an update: with owner's manual in hand, I again went to adjust my stereo. It turns out that the bass and treble were also at max. I mistook the midpoint marker for the point of adjustment. I adjusted bass to the midpoint, approximately 5 and adjusted treble down to about 8. My stereo finally sounds normal and my car is now completely un-hip-hopped.
