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.

WARNING

• 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 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.
