[. . . ] Private households in the member states of the EU, in Switzerland and Norway may return their used electronic products free of charge to designated collection facilities or to a retailer (if you purchase a similar new one). For countries not mentioned above, please contact your local authorities for the correct method of disposal. By doing so you will ensure that your disposed product undergoes the necessary treatment, recovery and recycling and thus prevent potential negative effects on the environment and human health. Example of installation on the floor mat or on the chassis . [. . . ] Output of 4 V or more, adjust level to match the car stereo output level. In this case, it is necessary to use the supplied speaker input wire with RCA pin cord. This unit is equipped with a protective function to prevent malfunction of the unit itself and speakers from too much output, improper use or improper connection. â· When outputting sound at high volume etc. , this function will cut off the sound output in a few seconds. When you turn down the volume of the head unit the sound output will be restored. â· If sound output is cut, the gain control of this unit may be improperly set. To ensure continuous sound output at increased volume of the head unit, set the gain control of the amplifier to a proper position according to the preout maximum output level of the head unit. There is no need to decrease the volume of the head unit and too much output is controlled. â· If you decrease the volume of the head unit and set the gain control of the amplifier to the proper position but still the sound cuts out from time to time, contact the nearest authorized PIONEER Service Station. Relationship between the gain of the amplifier and the output power of the head unit Power Normal gain Equal power Power Maximum gain If you raise the gain of the amplifier to an improper level, only distortion is increased and the power increases only slightly. Install and route the separately sold battery wire, ground wire, speaker wires and the amplifier as far away as possible from the antenna, antenna cable and tuner. Subwoofer Other than subwoofer Subwoofer Other than subwoofer Subwoofer Other than subwoofer Subwoofer Other than subwoofer This diagram shows connections using external output (subwoofer output). When you connect with speaker output, connections defers from the diagram. for details , see the "Using the Speaker Input" section. In either case, you need to set the input switch. for details , see the "Setting the Unit" section. Grommet Special red battery wire [RD-228] (sold separately) After making all other connections at the amplifier, connect the battery wire terminal of the amplifier to the positive (+) terminal of the battery. Ground wire (Black) [RD-228] (sold separately) Connect to metal body or chassis. External Output If only one input plug is used, do not connect anything to RCA input jack B. The female terminal can be connected to the auto-antenna relay control terminal. If the car stereo does not have a system remote control terminal, connect the male terminal to the power terminal through the ignition switch. [. . . ] As a result of connecting the car stereo speaker output wire to the amplifier, the power of the amplifier is turned on automatically when the car stereo is turned on. It is not necessary to connect the system remote control wire in this case. â· In the case the amplifier and head unit are connected using a speaker input wire with RCA pin cord, the amplifier power is only turned on when one amplifier is being used. If two or more amplifiers are synchronously connected in combination, connect the head unit and all of the amplifiers with the system remote control wire. [. . . ]
