High powered audio systems in a vehicle are capable of generating “Live Concert”
high levels of sound pressure. Continued exposure to excessively high volume sound
levels may cause hearing loss or damage. Also, operation of a motor vehicle while
listening to audio equipment at high volume levels may impair your ability to hear
external sounds such as; horns, warning signals, or emergency vehicles, thus
constituting to a potential traffic hazard. In the interest of safety, Consumer
Electronics recommends listening at lower volume levels while driving.
