Installation Precautions - Pyle Hydra PLMR440PA Owner's Manual

Installation precautions
Before you drill or cut any holes, investigate your vessel's layout very carefully.
Take special care when you work near the gas tank, fuel lines, hydraulic lines
and electrical wiring.
Never operate the amplifier when it is unmounted. Attach all audio system
components securely within the amplifier to prevent damage, especially in an
accident.
Do not mount this amplifier so that wire connections are unprotected, in a
pinched condition, in contact with any metal surfaces in your marine vessel,
or likely to be damaged by nearby objects.
Before making or breaking power connections in your system, disconnect the
marine vessel battery. Confirm that your head unit or other equipment is turned
off while connecting the input jacks and speaker terminals.
If you need to replace the power fuse, replace it only with a fuse identical to that
supplied with the amplifier. Using a fuse of a different type or rating may result
in damage to your audio system or your amplifier which is not covered by the
manufacturer's warranty.
Don't misuse the
level controll
Do not mistake the Input level control for a volume control I It Is designed
ONLY to match the output level of your audio source to the input level of
your amplifier.
Do not adjust this Input level to maximum unless your Input level requires It.
Ignoring these instructions will result in an input overload to the amplifier,
and excessive audio distortion. It can also cause the protection circuit to
engage.
