5. Stereo Gain Control – This feature is used to fine-tune the input sensitivity of the amplifier to the source unit’s output level. 6. Switchable Hi, 12dB / Low, 24dB @ 85Hz X-over– This switch is used to pick the preferred frequency range the amplifier will play. A high pass, low pass, or full range output may be selected. The upper end of the low pass crossover is 85Hz at 24dB per octave with a mono output. The lower end of the high pass crossover is 85Hz at 12dB per octave with a stereo

Connections 1. Bi-Level Inputs (Low/High Level Input) with Smart Engage™ – Both a low and high level signal can be used. Be sure to lay the signal wire away from all power cables and vehicle computers. Use high quality twisted pair interconnect cables to decrease the possibility of radiated noise entering the system. • Using RCA Connections: If the source unit has RCA outputs, simply attach a signal cable from the source unit to the amp’s RCA input. This will provide signal to the amp. •

Note: When numerous amplifiers are used in the same system, look into using a relay with a separate power wire connected to an alternative power source to take the strain off the source unit. Normal source units can only keep a constant 12 volts to 2 or possibly 3 amps. This wire should also be run on the away from RCA cables. • CAP+: This 8 gauge terminal is internally wired in parallel with the +12V on the StreetWires Power connector. It is the ideal connection point for the positive side o

5. Remote Subwoofer Level Control (Remote Gain) – Let’s say the amplifier’s gain is set at halfway, when the remote subwoofer level control is plugged in, you now have external control of the gain from zero to halfway. The installation of this level control is NOT necessary to get full power from the amplifier. 6. Prizm EFX – Now that you have completed adjusting all your amplifier settings, you can set the lighting effects to your personal taste. • Selecting Colors: You can change the backli
