Important Information
Congratulations on your purchase of an Aquatic AV AD500.4 4/3/2 Channel
Amplifier. It has been designed, engineered and manufactured to bring you the
highest level of performance and quality. Thank you for making Aquatic AV
your choice for marine audio equipment!
1.1 Using Your Amplifier
Working Safely With Your Battery
Disconnect the negative battery terminal before doing any electrical work. Al-
ways disconnect the negative (-) battery post first, followed by the positive (+).
When it’s time go back together, connect the positive (+) post first, followed by
the negative (-). This can minimize the chance of sparks and voltage spikes.
Grounding
Always use the shortest length of ground wire possible between chassis
ground and the amplifier. Never use a ground wire longer than the one we
provide.
The ground wire and power wire are equally important; if either one of them is
compromised, the amplifier’s performance will degrade or cease to function.
Fuses
Always install a master fuse within 12” of the battery for any additional equip-
ment added to your installation’s electrical system. The mini-fuse installed
on the main amplifier only protects the internal circuitry, not the wiring. In the
event of a short, failure to install a fuse near the battery can cause damage to
your electrical system or the possibilty of fire.
Speaker Polarity
The way speaker wires are marked for polarity (+/-) varies from brand to brand.
Some manufacturers use the stripe as positive (+), while others use the stripe
as negative (-). Be sure to check the documentation of each component you’re
dealing with before making connections.
Cutting Cables
Always route wires and cables safely, avoid sharp edges and burrs along the
way. Use wire loom when possible. Check for proper length to both termination
points, knowing where each component mounts, before you cut anything.
Mounting
Mount the amplifier away from water/mud at all times and in a good ventilated
area with good air flow. Do not mount in engine compartment. Mount amplifier
securely. Be careful not to drill into fuel line, electrical or mechanical areas
when mounting. Do not run wires under the vehicle or vessel, this could be very
dangerous with severe damage.
