Setting the Unit ENGLISH Thank you for purchasing this PIONEER product. Before attempting operation, be sure to read this manual. In case of trouble When the unit does not operate properly, contact your dealer or the nearest autho- rized PIONEER Service Station. 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. WARNING • We recommend that you use the special red bat- tery and ground wire [RD-228], which is sold sep- 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 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.

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. Power Indicator (Blue) The power indicator lights when the power is switched on. BFC (Beat Frequency Control) Switch If you hear a beat while listening to an AM broadcast with your car stereo, change the BFC switch using a small standard tip screwdriver. LPF (Low-Pass-Filter) Cut Off Frequency Control You can select a cut off frequency from 40 Hz to 240 Hz. Bass Boost Control You can adjust a bass boost level from 0 dB, 6 dB and 12 dB. Input Switch It is possible to input from a car stereo external output or a car stereo speaker output. Swit the input switch before turning on the power.

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 spea er input wire with RCA pin cord. For details, see the “Using the Speaker Input” section.
