Congratulations on your purchase of an Aquatic AV AQ-AD300.2-MICRO amplifier. It has been
designed, engineered and manufactured to bring you the highest level of performance and quality,
and will afford you years of listening pleasure.
Check your battery and electrical system
Low battery conditions and/or poor electrical systems need to be diagnosed and corrected prior to
installation of your amplifier. Old batteries may be good enough to start your engine, but may NOT be
adequate to power a high output audio system. Running your amplifier in a low-voltage situation may
cause premature distortion, fuse blowout, and system shutdown.
Working safely with your battery
Disconnect the negative battery terminal before doing any electrical work. Always disconnect the
negative (–) battery terminal first, followed by the positive (+) terminal. When reconnecting terminals,
connect the positive (+) terminal first followed by the negative (–) terminal. This can minimize the
chance of sparks and voltage spikes, and is a good general practice when dealing with any DC electri-
cal system.
Ensure proper power and ground connections
Never connect or disconnect the control cables while the amplifier(s) is powered on.
Always disconnect your battery before working with your electrical system, and keep it disconnected
until you are ready to test the audio system.
Cover all exposed wires to avoid short circuits.
Make your power and ground connections properly, failure to do so can cause damaged to the ampli-
fier.
Grounding
Inadequate grounds are number one cause of problem installations.
The ground wire and power wire are equally important; if either one of them become damage it could
result in damaged to the amplifier.
