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.
· 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
· 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
· 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
