Before You Begin
Exposure to loud sounds or music can
permanently damage your hearing.
Unfortunately, in many cases, the damage is
not noticeable until years later. In addition, loud
music may hinder your ability to hear traffic,
police, and fire or emergency vehicles. Be
responsible and have respect for other people
by listening at moderate volumes!
CAUTION: This device is a high-power audio
amplifier intended for installation in
vehicles with a 12-Volt negative ground
electrical system. Attempting to connect or
operate the amplifier in another type of
electrical system may cause damage to the
amplifier or the electrical system.
