Most devices have a built in volume control, but our amplified speaker systems come with an in-line volume controls just make it easier to control the volume while on the go.
If you have an iPhone or Andorid phone, we recommend visiting your APP Store and downloading a speed based volume control, the prices of these range from FREE to around 3.00. These are great cause after a few settings, when you roll up to a stoplight it will turn down the volume, and when you hit the highway it will turn it up.
