Selecting fine audio equipment such as the unit you’ve just purchased is only the start of your
musical enjoyment. Now it’s time to consider how you can maximize the fun and excitement your
equipment offers. This manufacturer and the Electronic Industries Association’s Consumer
Electronics Group want you to get the most out of your equipment by playing it at a safe level.
One that lets the sound come through loud and clear without annoying blaring or distortion—and,
most importantly, without affecting your sensitive hearing.

Sound can be deceiving. Over time your hearing “comfort level” adapts to higher volumes of
sound. So what sounds “normal” can actually be loud and harmful to your hearing. Guard against
this by setting your equipment at a safe level BEFORE your hearing adapts.

To establish a safe level:

• Start your volume control at a low setting.

• Slowly increase the sound until you can hear it comfortably and clearly, and without distortion.

Once you have established a comfortable sound level:

• Set the dial and leave it there.

Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all,

we want you listening for a lifetime.

We Want You Listening For A Lifetime

Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since
hearing damage from loud noise is often undetectable until it is too late, this manufacturer and the
Electronic Industries Association’s Consumer Electronics Group recommend you avoid prolonged
exposure to excessive noise. This list of sound levels is included for your protection.

Decibel
Level Example

30 Quiet library, soft whispers
40 Living room, refrigerator, bedroom away from traffic
50 Light traffic, normal conversation, quiet office
60 Air conditioner at 20 feet, sewing machine
70 Vacuum cleaner, hair dryer, noisy restaurant
80 Average city traffic, garbage disposals, alarm clock at two feet.

THE FOLLOWING NOISES CAN BE DANGEROUS UNDER CONSTANT EXPOSURE

90 Subway, motorcycle, truck traffic, lawn mower
100 Garbage truck, chain saw, pneumatic drill
120 Rock band concert in front of speakers, thunderclap
140 Gunshot blast, jet plane
180 Rocket launching pad

About This Product

This product is a class D amplifier for the
subwoofer. If both L (left) and R (right)
channels are connected to the RCA input
of this product, output is mixed because
this product is a mono amplifier.

CAUTION

Never replace the fuse with one of greater
value or rating than the original fuse. Use
of an improper fuse could result in over­heating and smoke and could cause dam­age to the product and injury including
burns.

WARNING

• Handling the cord on this product or cords associ­ated with accessories sold with the product will
expose you to lead, a chemical known to the State
of California and other governmental entities to
cause cancer and birth defects or other reproduc­tive harm. Wash hands after handling.

• Always use the special red battery and ground
wire [RD-223], which is sold separately. Connect
the battery wire directly to the car battery positive
terminal (+) and the ground wire to the car body.

• Do not touch the amplifier with wet hands.
Otherwise you may get an electric shock. Also, do
not touch the amplifier when it is wet.

• For traffic safety and to maintain safe driving
conditions, keep the volume low enough so that
you can still hear normal traffic sound.

• Check the connections of the power supply and
subwoofer if the fuse of the separately sold bat­tery wire or the amplifier fuse blows. Detect the
cause and solve the problem, then replace the fuse
with another one of the same size and rating.

• To prevent malfunction of the amplifier and sub­woofer, the protective circuit will cut the power
supply to the amplifier (sound will stop) when an
abnormal condition occurs. In such a case, switch
the power to the system OFF and check the
connection of the power supply and subwoofer.
Detect the cause and solve the problem.

• Contact the dealer if you cannot detect the cause.

• To prevent an electric shock or short-circuit
during connection and installation, be sure to
disconnect the negative (–) terminal of the battery
beforehand.

• Confirm that no parts are behind the panel when
drilling a hole for installation of the amplifier. Be
sure to protect all cables and important equipment
such as fuel lines, brake lines and the electrical
wiring from damage.

CAUTION:

To prevent damage and/or injury

• Do not ground the speaker wire directly or con­nect a negative (–) lead wire for several speakers.

• This unit is for vehicles with a 12-volt battery and
negative grounding. Before installing it in a recre­ational vehicle, truck or bus, check the battery
voltage.

• If the car stereo is kept on for a long time while
the engine is at rest or idling, the battery may go
dead. Turn the car stereo off when the engine is at
rest or idling.

• If the system remote control wire of the amplifier
is connected to the power terminal through the
ignition switch (12 V DC), the amplifier will
always be on when the ignition is on— regardless
of whether the car stereo is on or off. Because of
this, the battery could go dead if the engine is at
rest or idling.

• Connect a subwoofer with a 380 W or larger nom­inal input and an impedance between 1 and 8
ohms to the amplifier. If the nominal input and
impedance are out of the above ranges, the sub­woofer may catch fire, emit smoke or become
damaged.

• Install and route the separately sold battery wire
as far away as possible from the speaker wires.
Install and route the separately sold battery wire,
ground wire, speaker wires and the amplifier as
far away as possible from the antenna, antenna
cable and tuner.

• Cords for this product and those for other prod­ucts may be different colors even if they have the
same function. When connecting this product to
another product, refer to the supplied Installation
manuals of both products and connect cords that
have the same function.

Connecting the Unit

CAUTION

• Disconnect the negative (–) terminal of the battery
to avoid the risk of short-circuit and damage to
the unit.

• Secure the wiring with cable clamps or adhesive
tape. To protect the wiring, wrap adhesive tape
around it where they lie against metal parts.

• Do not route wires where they will get hot, for
example where the heater will blow over them. If
the insulation heats up, it may become damaged,
resulting in a short-circuit through the vehicle
body.

• Make sure that wires will not interfere with mov­ing parts of the vehicle, such as the gearshift,
handbrake or seat sliding mechanism.

• Do not shorten any wires. Otherwise the protec­tion circuit may fail to work when it should.

• Never feed power to other equipment by cutting
the insulation of the power supply wire to tap
from the wire. The current capacity of the wire
will be exceeded, causing overheating.

• Never replace the fuse with one of greater value
or rating than the original fuse. Use of an improp­er fuse could result in overheating and smoke and
could cause damage to the product and injury
including burns.

Setting the Unit

Bass Level Control

If the sound level is too low, even when
the volume of the car stereo used along
with this power amplifier is turned up,
turn bass level control on the front of the
power amplifier clockwise. If the sound
distorts when the volume is turned up,
turn the bass level control counter-clock­wise.

• When using with an RCA equipped car
stereo (standard output of 500 mV), set to
the NORMAL position. When using with
an RCA equipped Pioneer car stereo with
max. output of 4 V or more, adjust level to
match the car stereo output level.

• When you want to boost bass, turn the bass
level control clockwise.

Power Indicator

The power indicator lights when the
power is switched on.

Cut Off Frequency Control

You can select a cut off frequency from
40 to 240 Hz.
