PLEASE READ THIS INSTRUCTION MANUAL BEFORE INSTALLATION
AND OPERATION
IMPORTANT INFORMATION
Please read these notes before you begin installation. We also strongly recommend that you thoroughly read and understand the installation instructions
included.
Avoid over-driving your speakers
Follow the instructions given to properly set gain and frequency adjustments. If your
system conguration results in settings outside the typical range and something maybe
wrong, please contact your local Aquatic AV dealer or Aquatic AV Technical Support.
GAIN FREQ
Gain:
Typically set to around
75% or 3/4.
These are general rules
and depending on your
speaker & musical
preference these can be
adjusted.
HI
LO
Hi/Low Level Input:
Set to ‘HI’ if using speaker
wires as the signal input.
Set to ‘LO’ if using RCA/
Phono cables as the
signal input.
HP
LP
Hi/Low Pass Filter:
Set to ‘HP’ to allow all
frequencies above the
selected ‘Cross Over
Frequency’ setting.
Set to ‘LP’ to allow all
frequencies below the
‘Cross Over Frequency’
setting (these are ‘bass’
frequencies for when
running a subwoofer).
Cross Over Frequency:
Used to the set the
frequency by which the
‘Hi/Low Pass Filter’ starts
ltering or removing
unwanted frequencies.
Subwoofers will typically
run 50Hz-125Hz.
Full range speakers (e.g.
6.5”) will typically run 150Hz
and above.
Check your battery and electrical system
Low battery conditions and poor electrical systems should be diagnosed and corrected
before installing your amplier. Old batteries may be good enough to start your engine
but may not be up to the task of powering a high output audio system. Running your
amplier in a low-voltage situation can cause premature distortion, fuse blowout, and
system shutdown.
Ensure proper power and ground connections
Never connect or disconnect the control cables with the ampler(s) powered on.
Always disconnect your battery before working with your electrical system, and keep it
disconnected until you are ready to test.
Cover all exposed wires to avoid shorts.
Make your power and ground connections exactly as the instructions specify.

IMPORTANT INFORMATION
USING YOUR AMPLIFIER
Working safely with your battery
Disconnect the negative battery terminal before doing any electrical work. Always
disconnect the negative (–) battery post rst, followed by the positive (+), and when it’s
time to go back together, connect the positive (+) post rst, followed by the negative
(–). This can minimize the chance of sparks and voltage spikes, and is a good general
practice when dealing with any DC electrical system.
Grounding
Bad grounds under are the number one cause of problem installs.
Always use the shortest length of ground wire possible between chassis ground and
the amplier. 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 amplier’s performance will degrade or cease to function.
Fuses
Always install a master fuse within 12” of the battery for any additional equipment
added to your installations electrical system. The mini-fuse installed on the main amplier 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 possibility of re.

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, avoiding 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.

TERMINOLOGY
AQ-AD300.2
Source Unit: refers to the device that supplies the amplier with audio input, typically
your radio, head unit, media device, etc.
Main Amplifier: AQ-AD300.2, master 2 channel amplier that functions standalone.
Remote turn-on wire: used to switch the amplier system on/off, usually controlled by
your ignition system, or by the remote lead of a source unit.
Low Level Input Cable: used when RCA connectors are the source of input to the
amplier.
High Level Input Wire: used when speaker wires are the only source of input to the
amplier, typically used with a factory source unit.
Manufacturer instructions: refers to any documentation provided by a manufacturer
other than Aquatic AV.

SHOCKWAVE TECHNOLOGY™
Aquatic AV’s Shockwave Technology brings together outstanding sound quality, high performance characteristics and unprecedented reliability into a single
amplifier.
Protected against water and dust with an Ingress Protection rating of IP66 means you
can literally hose down our Shockwave Technology ampliers thanks to a number of
unique features exclusive to Aquatic AV (patents pending).
Conformal coated circuit boards protect the smallest components from any humidty or
atmospheric moisture, while custom molded grommets around cable extrusions and
gaskets between all meeting points eliminate any chance of water or dust intrusion.
Aluminium and Stainless Steel are used in chassis construction eliminating any risk of
rust or corrosion.
Designed to support the widest variety of applications, Shockwave Technology ampliers operate both 4ohm and 2ohm speaker congurations, from either low-level (RCA)
or high-level (speaker) input connections.
Shockwave Technology incorporates Digital IC’s with specially designed low-noise
circuitry to produce high-quality, true sound reproduction from any source. The technology used also reduces unwanted EMI ( Electromagnetic Interference), which can
cause noise in your audio system. Using gold plated RCA’s and high quality connectors ensures the best possible listening experience. Digital ampliers are much more
efcient than traditional ampliers; producing less heat, lowering power consumption,
reducing strain on batteries and charging systems.
Shockwave Technology ampliers combine all these features into a single compact unit
and when compared with the competition, still make considerable reductions in both
size and weight!
Aquatic AV’s Shockwave Technology is now the only sensible amplier solution for wet,
dusty or harsh environments.

INSTALLATION
WIRING THE AMPLIFIER
1. Route and connect the power wire (without the in-line fuse installed) from the positive (+) battery terminal to the main amplier terminal labeled PWR.
Do not install the in-line fuse until instructed to do so.
2. Route and connect the ground wire from chassis ground to the amplier terminal
labeled GND.
The majority of problem installs are the result of a poor ground. Refer to section
‘Ensure proper power and ground connections’ in the Important Information’
section for more information.
3. Determine and connect your source unit output to the amplier input cable(s) using
one of the following high or low level input methods:
3.1. High Level (Speaker) Input Wires: Use if no RCA connectors are available.
Connect the front speaker output wires from the source unit to the High Level input
cable (use attached terminals to connect input wires to the speaker wire terminals if
possible).
For custom wiring connections, we recommend crimp, solder, and heat shrink.
AQ-AD300.2
High Level (Speaker) Input Wires
2 Channel - use Front only
4 Channel - use both
Front Left + White
Front Left - White with Black strip
Front Right + Grey
Front Right - Grey with Black strip
3.2. Low Level (RCA) Input Cables: Preferred if RCA connectors are available.
Connect the front RCA output connectors from the source unit to the Low Level input
cable and input jack on the front of the amplier.
Very little dielectric grease is needed to keep your connections corrosion free.
Very little moisture is needed to corrode contacts not covered with dielectric grease.
4. Plug the chosen input cable into the corresponding connector of the main amplier
labeled high or low accordingly.
These wire colors correspond
to an Aquatic AV Source Unit
harness. If using a High-Level
source other than from Aquatic
AV, these colors could vary.
