NOTE: Do not overlook the use of the proper gauge speaker wire. The Power series of amplifiers require a minimum of 12-gauge wire.

Connect an RCA cable from your receiver to the RCA input on your amplifier. Power 400/880 Power 900/1050 Power 760/920 The Power 760 and 920 can be configured for three different input modes: 2 channel, 3 channel or 4 channel.

Choose a high quality low capacitance cable for the best results. Connecting Additional Amplifiers Pass-Thru RCA connectors are provided to connect additional amplifiers without the need to purchase "Y" adapters. min max 0dB 12dB 40Hz 300Hz 40Hz 300Hz min max 0dB 12dB 40Hz 300Hz 40Hz 300Hz LEVEL BASS EQ HPF LPF X-OVER FULL LPF HPF FULL LPF HPF 2 3 4 MODE LINE OUT CH3 CH4 CH1 CH2 LINE INPUT 4 Channel 2 3 4 MODE POWER Amplifiers 10 Indicators and Controls Power Indicator (POWER) The power indicator provides a visual indication that the amplifier is turned on. Input Level Control (LEVEL) The input LEVEL control matches the output of your radio to the input of the amplifier. After the installation is complete, make sure the input level control on the amplifier is turned down all the way (counter-clockwise or all the way to the left). Play a tape or CD (make sure bass and treble settings or Bass EQ are flat) and turn the volume up slowly until you just start to hear distortion. Back the volume down just a bit. On the amplifier, slowly turn up the input level control (clockwise or to the right) until you just start to hear distortion, then back it down a bit. Now your radio and amplifier levels are matched. BASS EQ The Bass EQ is continuously adjustable from 0 to +12dB @ 45Hz. Adjusting the Bass Boost level allows different subwoofer/enclosure combinations to be equalized. Use this control to increase the level of low bass available from your subwoofer/enclosure combination. Ported and Band Pass enclosures should be limited to about +6dB to +9dB of boost. Sealed enclosures should be able to accept the full +12dB of boost, if necessary. The full +12dB of boost should be reserved for special applications since improper use of the Bass Boost could damage your subwoofers at high volumes. Low Pass Filter (LPF) The Low Pass Filter controls adjust the crossover point. Typical crossover is between 60Hz and 80Hz for ported and sealed enclosures. Bandpass boxes will typically use a higher crossover setting between 125Hz and 150Hz. Since musical tastes vary, you should play music that you would normally listen to in your vehicle, with the above setting...
