RUBITM (Rapid-Use Branched jmpulse) This new proprietary power supply topology eliminates “power sags” during low frequency reproduction by rapidly increasing the duty cycle, stabilizing the power supply and allowing it to deliver the power required when reproducing low frequencies. Also, greater reserve gate power is stored for low voltage situations that occur during extreme conditions. STACTTM (STabilized Apex Qrrent _Topology) Reduces power supply stress by 50%.

The RUBICON amplifiers incorporate an on-board staggered electronic crossover, with RCA outputs (RUBICON only) to drive an external amplifier. No external electronic crossover is necessary. However, if you do desire to use an external crossover you still have that option. The high and low pass portions of the crossover can be set independently of one another. In many car audio installations, there is a tendency for a “midbass boom.
INSTALLATION STEP 1 Hawkins Bass Control - Theorv and Use Hawkins Bass Control (variable) is a unique subwoofer control circuit included with the Soundstream RUBICON amplifier. It is capable of removing subsonic energy in program material below 45 Hz at 12 dB/Octave, while boosting subwoofer frequencies. The circuit consists of two controls. One engages a subsonic High Pass filter at 45 Hz, and the other adjusts the amount of boost (0 to +9 dB) (fixed at +6dB for the RUBCON & 355).
f INSTALLATION STEP 2 ] ( INSTALLATION STEP 3 INSTALLATION AND MOUNTING POWER AND GROUND To ensure maximum output from your RUBICON amplifier, use high quality, lowloss power and ground cables and connections. The RUBICON amplifiers will accept up to 4 or 8 gauge power and ground cables.
