High-powered car audio
systems may produce

sound pressure levels that exceed the
threshold at which hearing loss may
result. 

They may also impair a driver’s ability to
hear traffic sounds or emergency vehi-
cles.  Use common sense and practice
safe listening habits when listening to or
adjusting your audio system.
