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.
ENGLISH
WARNING
• We recommend that you use the special red bat- |
tery and ground wire |
arately. 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 |
during connection and installation, be sure to |
disconnect the negative |
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. |
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.

• 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. |
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.
Bass Boost Control
You can adjust a bass boost level from 0 dB to 12 dB.
For instruction of connecting the bass boost remote control to the amplifier, see the “Connection Diagram” section.
