5. ssis Coat this connection with terminal grease or petroleum jelly This location should be no more than three 3 feet from the amplifier REMOTE This terminal should be connected to the remote turn on lead of the head unit or cascaded from another remote mounted device For head units with no auto antenna output a separate switch should be wired to allow the amp s be turned on or off manually SPEAKER CONNECTIONS Speaker Connect the right positive and negative speaker leads to the corresponding amplifier terminals Repeat this process for the left speaker taking care to maintain correct polarity For mono Operation connect the speaker positive to the amplifiers right positive and the speaker negative to the amplifiers left negative Mixed mono systems may be built using the stereo and mono hookups simultaneously although this may require the use of a passive crossover AMPLIFIER OPERATION STEREO MODE To use the amplifier in the stereo mode connect the right and left RCA inputs to the proper jacks on the head unit or crossover Set the stereo mono switch to the stereo position Turn the gain counter clockwise to a low level Connect the power ground remote and speaker wires to their proper terminals as described in previous section MONO MODE To use the amplifier in the mono mode connect either the right or left RCA input to an output jack on the head unit or crossover Set the stereo mono swi
