Ensure the +12V lead is disconnected from the battery before you connect any new equipment.
LEVEL CONTROL This control is used to match the input level of the amplifier to the output level of you head unit. We recommend the following method. NOTE: Remove screws and the top cover of amplifier to access controls. 1. Turn the amplifier level to zero 3. 2. Turn the volume of the head unit to and the bass and treble to zero Adjust the level control until the desired maximum volume is achieved without distortion. 4. Failure to follow these steps may cause permanent damage to the audio system.

SERIES AND PARALLEL SUBWOOFER WIRING FOR DUAL VOICE COIL SUBWOOFERS PARALLEL VOICE COIL WIRING (2 OHM OPERATION) To wire a 4 Ohm DVC subwoofer in parallel to get 2 Ohm, use two short pieces of speaker wire and link the positive from one coil to the positive of the second coil, and do the same for the negative as shown below. Then wire the amplifier to opposite sides of the subwoofer in order to equalise any connection resistance.
PARALLEL WIRING FORMULA FOR 2 SPEAKERS 4 Ohm 8 Ohm 2.67 Ohms R1 x R2 = R1 + R2 LOAD IMPEDANCE 4 Ohms x 8 Ohms 4 Ohms + 8 Ohms = 32 12 SERIES WIRING FORMULA FOR 2 SPEAKERS 4 Ohm 4 Ohm 8 Ohms R1 + R2 = LOAD IMPEDANCE 10 = 2.
