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 tighten
screws when fastening wires to the terminal. 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
associated with accessories sold with the product
may expose you to chemicals listed on
proposition 65 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
subwoofer if the fuse of the separately sold bat-
tery 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 sub-
woofer, 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.
· 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
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 counterclockwise.
· 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.

Power Indicator (Blue)
The power indicator lights when the power is switched on.
LPF (Low-Pass-Filter) Cut Off Frequency Control
You can select a cut off frequency from 40 Hz to 240 Hz.
Bass Boost Control
You can select a bass boost level from 0 dB, 6 dB and 12 dB.
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 right (RCA).
For connection instructions, see the "Connection Diagram" section. When using a speaker
output, slide the switch to the left (SP). In this case, it is necessary to use the supplied speak-
er input wire with RCA pin cord. For details, see the "Using the Speaker Input" section.
