Page 5: System Planning
YSTEM LANNING Before wiring up an audio system that may not achieve the sound quality you want, be sure to choose a system concept that fits your listening requirements. Basic systems, a receiver with internal 4x20 watts and 4 coax speakers, are adequate for many listeners. - Page 6 EHICLE IRING VEHICLE FUSING For safety purposes, a high current fuse (or circuit breaker) MUST be installed in line with the amplifiers(s) immediately at the battery to prevent vehicle damage should the battery line in advertently shorted to the vehicle chassis. The chart at the right shows the recommended master fuse sizes for an average audio system with noted “rms”...
- Page 7 & C NPUTS ONTROLS The inputs and controls for this amplifier are explained in the summaries below and reference the numbered call-outs above. 1.)

- Page 8 OWER ONNECTIONS 1.) POWER CONNECTIONS - GROUND - This is the high current ground connection to the chassis of the car. It should be fastened to a clean ground connection in the car, capable of handling high current loads and within 3 feet (absolutely no longer than 3 feet).
- Page 9 YSTEM ONFIGURATION Full-Range Full-Range 3 Channel Multi-Mode (Active) This amplifier offers a very unique installation advantage by including 3 independent amplifier channels with 2 active crossover sections. The inputs require only 2 signal leads (left and right) and derive the bass signal from these two. The final installation is most commonly configured with the two stereo channels driving satellite speakers in the flat or high- pass mode for maximum sound pressure level.
- Page 10 YSTEM ONFIGURATION Full-Range Full-Range 2 Channel Dual Subwoofer Mode The largest improvement in sound quality always comes when adding some kind of subwoofer via a dedicated subwoofer amplifier and electronics crossover. The electronic crossover ensures minimal overlap of the bass response with the mid and high frequencies from the other speakers resulting in a more accurate performance compared to conventional coaxials with additional power.
