PROTECT YOUR HEARING!
We value you as a long-term customer. For
that reason, we urge you to practice restraint in
the operation of this product so as not to damage
your hearing and that of others in your vessel
or vehicle. Studies have shown that continuous
exposure to high sound pressure levels can lead
to permanent (irreparable) hearing loss. This and
all other high-power amplifiers are capable of
producing such high sound pressure levels when
connected to a speaker system. Please limit your
continuous exposure to high volume levels.
While driving, operate your audio system in
a manner that still allows you to hear necessary
noises to operate your vessel or vehicle safely
(horns, sirens, etc.).
SERIAL NUMBER
In the event that your amplifier requires
service or is ever stolen, you will need to have
a record of the product’s serial number. Please
take the time to enter that number in the space
provided below. The serial number can be found
on the bottom panel of the amplifier and on the
amplifier packaging.
