Speed sensitive volume raises or lowers the stereo’s volume as the vehicle gains or loses speed.
Tied into the speedometer, these circuits make incremental volume changes over the vehicle’s speed range. It’s a handy feature that saves you the trouble of adjusting the volume manually, as may be necessary as the background wind and road noise increase profoundly with speed. I find the controls most useful on rumbly sports cars and convertibles, and the better systems let the user select different levels of incremental boost. For example, I’ve used a lower setting to overcome engine rumble in the Chevy Corvette convertible with the top up and switched to a higher amount of boost to combat wind noise when the top was down. It may seem a luxury, especially if the car is equipped with steering-wheel-mounted volume controls. But what’s wrong with that?
