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] and [RD-222], which are sold sep­arately. Connect the battery wire directly to the
car battery positive terminal (+) and the ground
wire to the car body. There is the risk of a fuse
burning out if only one of these is connected.

• 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
speakers 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 speak­ers, 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 speakers.
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.

• DO NOT allow amplifier to come into contact with
liquids due to, for example, the location where the
amplifier is installed. Electrical shock could result.
Also, amplifier and speaker damage, smoke, and
overheating could result from contact with liquids.
In addition, the amplifier surface and the surface of
any attached speakers could become hot to the
touch and minor burns could result.

Setting the Unit

Power Indicator

The power indicator
lights when the power
is switched on.

Terminal Cover

Before setting up the unit, unfasten the
screws with a 4 mm hexagonal wrench
and remove the terminal cover.

Bass Boost Control

You can select a bass boost level from
0, 6, 9 and 12 dB.
For instruction of connecting the bass
boost remote control to the amplifier,
see the “Connection Diagram” section.

Switch

BFC switch is on the bottom of the unit.
If you hear a beat while listening to an
AM broadcast with your car stereo,
change the BFC switch using a small
standard tip screwdriver.

Subsonic Select Switch

The subsonic filter cuts inaudible
frequencies below 20 Hz to eliminate
unwanted vibrations and minimize
power loss.

• To adjust the switch, use standard tip screwdriver if needed.

Gain 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 gain control clockwise. If the sound distorts when the vol­ume is turned up, turn the gain 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.

• If you hear too much noise when using the speaker input terminals, turn the gain control
counter-clockwise.

Input Switch

It is possible to input from a car stereo external output or a car stereo speaker output. Switch
the input switch before turning on the power. Since switching the input switch while the
power is on can cause a loud noise to be emitted from the speakers, the power is turned off
by a protection function. When using an external output, slide the switch to the left. For
connection instructions, see the “Connection Diagram” section. When using a speaker out­put, slide the switch to the right. In this case, it is necessary to use the supplied speaker input
wire with RCA pin cord. For details, see the “Using the Speaker Input” section.

MODE SELECT Switch

You can select amplifier’s sync mode from MASTER, SYNC and SYNC INV. Set the
MODE SELECT switch to the MASTER position when using one amplifier only. When
using synchronously connecting two or more of these amplifiers in combination, set the first
amplifier to MASTER, and set the remaining amplifiers to SYNC or SYNC INV according
to the manner in which they are connected. The only time the amplifier is switched to the
SYNC INV mode is when amplifiers are synchronously connected with the ex. bridge.
When switching to the SYNC INV mode, the seal over the MODE SELECT switch must be
peeled off and you can find SYNC INV switch. Peel off the seal after checking that connec­tions are correct. See the “Connecting the Speaker Wires” section for details on the MODE
SELECT switch.

POWER MODE Switch

When using speakers with synthetic impeadance 2 Ωto 8 Ω, slide the switch to the right
(NORMAL). When using speakers with synthetic impeadance from 1

Ω

to less than 2 Ω,
slide the switch to the left (HI-CURRENT). These settings are only used when using a sin­gle amplifier. See the “Connecting the Speaker Wires” section when combining the use of
multiple amplifiers.
If the speaker impedance exceeds 2

Ω

(4 Ωwhen using ex. bridge), although the POWER
MODE switch be may set to the HI-CURRENT position, setting to the NORMAL position
makes it possible to enjoy high power sound.

Cut Off Frequency Control for LPF

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

Connecting the Unit

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.

• DO NOT connect a subwoofer with a lower
impedance than specified in the “Connecting the
Unit” section. Amplifier damage, smoke, and
overheating could result from a non-specified
connection. The amplifier surface could also
become hot to the touch and minor burns could
result.

• Connect either of three subwoofers to the amplifi­er; 1: a subwoofer with a 420 W or larger nomi­nal input and an impedance 4 Ω, 2: a subwoofer
with a 600 W or larger nominal input and an
impedance 2 Ω or 3: a subwoofer with a 600 W
or larger nominal input and an impedance 1 Ω. 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 manuals of
both products and connect cords that have the
same function.

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.

Connection Diagram

• This diagram shows connections using external output. Slide the input switch to the left.

• In the case of connecting the external output from a car stereo to an RCA input, use the jack used for full­range output. This is because the LPF of the amplifier cannot be turned OFF. If this jack cannot be used,
connect the subwoofer output jack to the RCA input.

• When you connect with speaker output, connections defers from the diagram. For details, see the “Using
the Speaker Input” section. In either case, you need to set the input switch. For details, see the “Setting the
Unit” section.

• Always use the special red battery and ground wire ([RD-223] and [RD-222]), which are sold separately.
Connect the battery wire directly to the car battery positive terminal (+) and the ground wire to the car
body. There is the risk of a fuse burning out if only one of these is connected.

Installation

CAUTION

• Do not install in:
—Places where it could injure the driver or pas-

sengers if the vehicle stops suddenly.

—Places where it may interfere with the driver,

such as on the floor in front of the driver’s
seat.

• Make sure that wires are not caught in the sliding

mechanism of the seats, resulting in a short-cir­cuit.

• Confirm that no parts are behind the panel when

drilling a hole for installation of the amplifier.
Protect all cables and important equipment such
as fuel lines, brake lines and electrical wiring
from damage.

• Install tapping screws in such a way that the

screw tip does not touch any wire. This is impor­tant to prevent wires from being cut by vibration
of the car, which can result in fire.

• DO NOT allow amplifier to come into contact

with liquids due to, for example, the location
where the amplifier is installed. Electrical shock
could result. Also, amplifier and speaker damage,
smoke, and overheating could result from contact
with liquids. In addition, the amplifier surface and
the surface of any attached speakers could
become hot to the touch and minor burns could
result.

• To ensure proper installation, use the supplied

parts in the manner specified. If any parts other
than the supplied ones are used, they may damage
internal parts of the amplifier, or they may
become loose causing the amplifier to shut down.

• 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.

CAUTION:

To prevent malfunction and/or injury

• To ensure proper heat dissipation of the amplifier,
be sure of the following during installation.

—Allow adequate space above the amplifier for

proper ventilation.

—Do not cover the amplifier with a floor mat or

carpet.

• DO NOT allow amplifier to come into contact
with liquids due to, for example, the location
where the amplifier is installed. Electrical shock
could result. Also, amplifier and speaker damage,
smoke, and overheating could result from contact
with liquids. In addition, the amplifier surface and
the surface of any attached speakers could
become hot to the touch and minor burns could
result.

• Do not install the amplifier on unstable places
such as the spare tire board.

• The best location for installation differs with the
car model and installation location. Secure the
amplifier at a sufficiently rigid location.

• Make temporary connections first and check that
the amplifier and the system operate properly.

• After installing the amplifier, confirm that the
spare tire, jack and tools can be easily removed.
