About This Product

This product is an amplifier for the sub- woofer. If both L (left) and R (right) chan- nels 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 over- heating and smoke and could cause dam- age to the product and injury including burns.

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.

•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.
