PROTECTION CIRCUITRy
The amplifier protection circuitry will disable the amplifier if
input overload, short circuit or extremely high temperature
conditions are detected. When the protection mode is in
operation, the LED indicator on the front panel will be
illuminated, indicating the amplier has gone into a
self-preservation mode.
lf you observe that the protection LED is lit, please check
the system carefully to determine what has caused the
protection circuit to engage. The amplifier can be reset by
turning the remote power OFF and then ON again. lf the
amplier shuts down due to a thermal overload condition,
please allow it to cool down before restarting. lf the shut
down is due to an input overload or short circuit, be sure
to repair these conditions before attempting to power up
the amplifier again.

GA9800 INSTRUCTION MANUAL PAGE 3
2 Ohm PROTECTION
Your GME GA9800 amplifier is designed to operate
efficiently at loads down to 2 Ohm. You can install four
8 Ohm speakers per channel when using parallel wiring,
increasing the number of woofers per channel at low
frequencies [up to 100 Hz]. This produces an acoustic
coupling effect, increasing your power output by 3 dB
per speaker, or the equivalent of additional 10W to
each speaker.
When operating at 2 Ohm, the amplier will increase its
output power by approximately 50%. The current draw will
also increase by about the same amount, so be sure you
have enough current to run the amplifiers into a 2 Ohm
load, lf you lack adequate current, your music reproduction
will be distorted.
Note: The gain control of any audio amplifier should not be
mistaken for a volume control. lt is a sophisticated device,
designed to match the output level of your audio source
unit to the input level of the amplifier. Do not adjust this
input level to maximum unless your input level requires it.
lgnoring these instructions will result in an input overload
to the amplier, and excessive audio distortion. lt can also
cause the protection circuit to engage.
ElECTRICal wIRINg
Your GME amplifier is equipped with easy top-access screw
terminals. These terminals are NICKEL Plated in order to
ensure excellent electrical contact, and to resist corrosion.
When making electrical connections to the amplier,
please observe the following:
• Use at least 4 gauge or heavier wires for power and
ground connections.
• Wire the amplier directly to the battery.
• For the ground connection, use the shortest possible wire
to a good chassis ground point.
• Wire the remote connection to the auto start lead of
your stereo.
FUSES
Power fuses protect both the amplifier and the electrical
system of your vessel from fault conditions. lf you must
replace the fuse in your amplier, use a fuse of exactly the
same type and rating. A different type or rating of fuse may
result in damage or fire.
mOUNTINg ThE amPlIFIER
Mark the location for the mounting screw holes by
positioning the amplifier where you wish to install it and
use a scribe [or one of the mounting screws] inserted in
each mounting hole to mark the mounting surface. lf the
mounting surface is carpeted, measure the hole centres
and mark with a felt tip pen.
Drill pilot holes in the mounting surface for the mounting
screws and insert the mounting screws into these holes.
Tighten them securely.
Note: Be sure to take note of any wires, lines or other
devices in your vessel which may be located behind any
mounting surface!
POwER SUPPly CONNECTIONS
The GA9800 amplifier is designed to work within 10 to
16 Volts DC. Before any wires are connected, the vessel’s
electrical system should be checked for correct voltage
supply with the help of a volt meter.
1. Check the voltage at the battery terminals with the
ignition in the OFF position. The Volt Meter should
read no less than 12 Volts.
2. Check the battery with the engine running between
1500 and 2000 rpms. The Volt Meter should now read
between 13.5 and 14.5 Volts.
Note: lf your vessel’s electrics are not up to these
specications, we recommend it to be checked by an
Marine Electrician before you continue with the installation.

amPlIFIER INSTallaTION
SUBWOOFER REMOTE CONTROL PRECAUTIONS
Before you drill or cut any holes, investigate your vessel’s
layout very carefully. Take care when you work near the gas
tank, fuel lines, hydraulic line and electrical wiring.
Do not operate the amplifier when it is unmounted. Attach
all audio system components securely within the vessel.
Do not mount this amplifier so that the wire connections
are unprotected or in a pinched condition, or likely to be
damaged by nearby objects.
Before making or breaking power connections in your
system, disconnect the vessel’s battery. Conrm that
your head unit or other equipment is turned OFF while
connecting the input jacks and speaker terminals.
lf you need to replace the power fuse, only replace it with a
fuse identical to that supplied with the system. Using a fuse
of a different type or rating may result in damage to your
system which isn’t covered by the manufacturer’s warranty.

TROUblEShOOTINg
No output 1. Confirm all terminal strip connections are secure and tight.
2. Check both in-line and built-in fuses. Both the ‘+ 12V’ and the ‘REMOTE’ terminal
must have + 12V referenced to chassis ground.
3. Conrm the audio signal source [radio, equalizer, etc.] is connected and is supplying
output signal. To check if the amplier is supplying signal, unplug the RCA cables from
the signal source [but leave them plugged into amp]. Briey tap the centre pin of each
of the disconnected RCA plugs with your nger. This should produce a noise [feedback]
in your speakers.
Only 1 Channel is working 1. Confirm all speaker strip connections are secure and tight.
2. Check the ‘BALANCE’ control on the head unit [or other source] to verify that it is set
to its midpoint.
3. If you are using the Low Level RCA input, reverse the input plugs at the amplier
[switch the R with the L]. If the channel which is silent switches to the other side,
the problem is either in the head unit/other source or the connecting cables.
Weak output Re adjust the Input Sensitivity Control to better suit input signal.
Noise in the audio 1. If the noise is a ’whine’ whose pitch follows the engine speed, conrm that the
amplier and any other signal sources [head unit, etc.] are properly grounded.
2. If the noise is a ‘clicking’ or ‘popping’ noise whose rate follows the engine speed,
this usually means the vessel is equipped with resistor spark plugs and wires, or that
the ignition is in need of service.
3. Check the routing of the speaker and input wires to make sure they are not adjacent
to wires which interconnect lights and other accessories. If the above steps fail to
improve or clear noise interference, the system should be checked by a professional
marine audio installer.

COMPLiANCE
This device complies with AS/NZS 61000.6.3:2007
This device complies with part 15 of the FCC rules. Operation is subject to the condition
that this device does not cause harmful interference.
LiSTENiNG TO FM iN YOUR BOAT
The majority of FM broadcasts are music programs. Compared with AM signals, FM
signals have a wider dynamic range, are relatively immune to noise and provide virtually
distortion free music reproduction. However, because of the nature of FM signals and
the fact that FM stations are usually positioned for shore based reception, reception in a
moving boat may be accompanied by problems.
FM programs are broadcast for local reception and may not be heard satisfactorily at
distant locations. To enjoy FM programs at their best, it is important that you tune to a
station that is broadcasting in your locality.
FM signals can reflect from solid objects such as buildings or hills. If these reflected
signals are received along with signals that are arriving directly from the transmitter, they
may mix together to produce what is known as ‘multipath distortion’. This distortion is
heard as noise. Often, moving as little as one metre from your position will correct
this problem.
FM signals travel in straight lines. Because the signals are reflected from or absorbed by
large solid objects, a signal ‘shadow’ may be present behind the object which may result
in poor reception in that area.
