If both L (left) and R (right)channels are connected to the RCA inputof this product, output is mixed becausethis product is a mono amplifier.CAUTIONNever replace the fuse with one of greatervalue or rating than the original fuse. Useof an improper fuse could result in over-heating and smoke and could cause dam-age to the product and injury includingburns.WARNING• Always use the special red battery and groundwire [RD-223] and [RD-222], which are sold sep-arately. Connect the battery wire directly to thecar battery positive terminal (+) and the groundwire to the car body. There is the risk of a fuseburning out if only one of these is connected.• 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 drivingconditions, keep the volume low enough so thatyou can still hear normal traffic sound.• Check the connections of the power supply andspeakers if the fuse of the separately sold batterywire or the amplifier fuse blows. Detect the causeand solve the problem, then replace the fuse withanother one of the same size and rating.• To prevent malfunction of the amplifier andspeakers, the protective circuit will cut the powersupply to the amplifier (sound will stop) when anabnormal condition occurs. In such a case, switchthe power to the system OFF and check theconnection of the power supply and speakers.Detect the cause and solve the problem.• Contact the dealer if you cannot detect the cause.• To prevent an electric shock or short-circuitduring connection and installation, be sure todisconnect the negative (–) terminal of the batterybeforehand.• Confirm that no parts are behind the panel whendrilling a hole for installation of the amplifier. Besure to protect all cables and important equipmentsuch as fuel lines, brake lines and the electricalwiring from damage.• DO NOT allow amplifier to come into contactwith liquids due to, for example, the locationwhere the amplifier is installed. Electrical shockcould result. Also, amplifier and speaker damage,smoke, and overheating could result from contactwith liquids. In addition, the amplifier surfaceand the surface of any attached speakers couldbecome hot to the touch and minor burns couldresult.
