PASSENGER MOUNTING Under the seat or floor mounting will work as long as there is a minimum of 1” (2.5 cm) of air gap above the amplifier heatsink. Vertical mounting of the amplifier is still the best. WIRING THE SERIES 1 Caution! Be sure to avoid running the power wires near the low level input cables, antenna, sensitive equipment or harnesses. The power wires carry substantial currents and could induce noise. 1. Power – The gold B+ terminal must be connected directly to the positive (+) term

4. Input – The amplifier’s signal input RCA jacks should be con- nected to the source unit’s signal outputs with high-quality braided or double-shielded interconnecting RCA cables. Note: Be sure to route the Series 1 signal input cable away from the main power wire and the car’s wiring harnesses to avoid noise coupling. If the source unit does not utilize RCA cables, connect the left and right positive speaker output wires from the source unit to the amplifier’s High Level Speaker Input Connect

ACTIVE CROSSOVER MODE SELECTIONS FOR 2600X AND 4600X THE The Series 1 2600x and the 4600x amplifiers feature a selectable electronic crossover. One module controls two output channels that can be configured in a High-Pass, Low-Pass, or Full Range (factory default) position. (Note: The 4600x has 2 modules as it is a 4-channel amplifier). Selection is made by positioning a removable module card. Both the 2600x and 4600x are shipped with 100Hz 12dB per octave Butterworth aligned crossover modules.
