4.Input – The amplifier’s signal input RCA jacks should be con- nected to the source unit’s signal outputs with
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 Connector. The center pin is then connected to the chassis of the source unit.
5.Speakers – Series 1 amplifiers are rated for safe operation into loads of 2Ω or greater in stereo mode, or 4Ω in bridged/mono configurations. The primary loads on any amplifier come from directly connected speakers without using capacitors. The mea-
sured resistance for each side should not be less than 2Ω stereo or 4Ω bridged/mono.
6.Bridged/Mono Configuration – The Series 1 amplifiers are ca- pable of bridged/mono configurations.
This configuration enables you to:
•Run a single woofer with stereo satellites
•Run two bridged amplifiers as a high power stereo system
•Run one amplifier with a bridged/mono woofer and another as a
Note: The 4600x allows the above 3 configurations all in one. For more information refer to the wiring diagrams beginning on page 14.
Note: To bridge the amplifier, use the L+ and R– speaker connectors.
CAUTION! Series 1 amplifiers are not recommended for imped- ance loads below 2Ω stereo or 4Ω bridged/mono.
Be sure to observe proper speaker terminal polarity throughout the system. It is critical for the Series 1 to use the correct negative terminal for right and left channels, since the RIGHT NEGATIVE
