This is a variable control filters out all Sub Bass Frequencies below the set point at 18dB/octave. 7 Level: This allows level adjustment of the input signal. Use this control to correctly match the head unit to the amplifier. To set this control correctly, turn the amplifier level to MIN and the head unit to 3/4 volume, with the BASS and TREBLE on zero , then slowly turn up this amplifier level control towards the MAX end of the control. NOTE: If the sound becomes distorted, turn this control down.
INSTALLATION 006 Installation Mounting Appropriate mounting is very important for the prolonged life expectancy of any amplifier. Select a location that allows enough space so sufficient airflow is maintainable and a location that provides protection from moisture. Keep in mind that an amplifier should never be mounted upside down. Upside down mounting will compromise heat dissipation through the heatsink and could engage the thermal protection circuit. Excessive heat will shorten your amplifiers life.
Ground When grounding your FUSION amplifier, use the same gauge cable for ground as you did for the power. Secure the ground cable to the appropriate ground point, now its time to connect the power and ground cables to the amplifier. Cut both cables to length. Use a hex type screwdriver to loosen the +12V and the GND connections on the amplifier. Terminate the ground first, and then the +12V and please make sure that you terminate them into the correct terminals. Then tighten the screws down securely.
INSTALLATION 008 Inputs & Gain Setup Low Level Inputs Be extra careful with your RCA interconnects. Hiss, engine noise, and fan noise can easily be picked up through RCA cables if run incorrectly. Avoid running your RCAs near large wire looms and electric fans if possible. Run your RCA cables on the opposite side of the power cable.
