Align the mounting holes in the bottom half of the crossover unit with the holes you have drilled at theinstallation site. Pass the four #6 x 1 1/4" screws through the holes in the crossover unit, and tighten themuntil the assembly is firmly in place. As before, do not over-tighten; this is especially important if themounting surface is not perfectly flat.After all the connections and any necessary adjustments have been made snap the cover back in place.connecting the systemTrim the speaker wire as needed. Strip about 1/4" (6 mm) of the insulation from the ends. Twist theexposed strands thoroughly to prevent any loose strands from causing a short circuit. You may also "tin"the wire with a soldering iron. The wires attach to a removable connector which in its assembled positionhas the screws facing the bottom of the crossover. Insert the prepared wire into the appropriate location(see diagram or refer to the crossover circuit board) in the connector strip and tighten the screws to securethe wires in place. Be sure to note the polarity marking on the circuit board.crossover connections and input switch settingRoute the wires connected to the input terminals on the crossover network to the power amplifier.Connect the wires to the amplifier outputs as recommended by the manufacturer of the unit. Make surethere are no stray strands of wire which could cause a short circuit. Observe left/right polarity markings.NOTE: In this configuration, you may connect the amplifier (+) positive to either the tweeter (+) or woofer(+) terminal, and the amplifier (-) negative to either the tweeter (-) or woofer (-) terminal. The parallelswitch ensures that both halves of the crossover are supplied with signal as least one (+) and (-) inputterminal are connected.TweeterWooferAmplifer CrossoverIN OUT+--+-+-+WooferTweeterWooferTweeter+-+-+-Standard(Switch in Parallel Position)Bi-amp Parallel11
