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.
·Use the supplied hexagonal wrench to tight-
en screws when fastening wires to the ter-
minal. The use of a long, commercially
available hexagonal wrench can cause
excessive torque to be applied possibly
resulting in damage to terminals and wires.
WARNING
·Handling the cord on this product or cords associat-
ed 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.
·We recommend that you use the special red bat-
tery and ground wire [RD-228], 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
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 speak-
ers, the protective circuit will cut the power supply
to the amplifier (sound will stop) when an abnor-
mal 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.
Top Cover
Before setting up the unit, unfasten
the screws with a 4 mm hexagonal
wrench and remove the top 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.
BFC (Beat Frequency Control)
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 elimi-
nate unwanted vibrations and min-
imize 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 vol-
ume 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 out-
put, 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 connect-
ed. The only time the amplifier is switched to the SYNC INV mode is when amplifiers are synchro-
nously connected with the ex. bridge.
When switching to the SYNC INV mode, the stopper over the MODE SELECT switch must be
removed and you can find SYNC INV switch. Remove the stopper 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
to 8 , slide the switch to the right
(NORMAL). When using speakers with synthetic impeadance from 1
to less than 2 ,
slide the switch to the left (HI-CURRENT). These settings are only used when using a sin-
gle amplifier. See the "Connecting the Speaker Wires" section when combining the use of
multiple amplifiers.
If the speaker impedance exceeds 2
(4 when 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.
