Ll\ 5 Bass Boost: This is a variable control to increase the bass boost at 45Hz from o -+I8dB of gain, adjust to suit. 6 Subsoni( Filter: This is a variable control filters out all Sub Bass Frequencies below the set point at I8dB/octave. 7 Level: This allows level adjustment of the input signal. Use this control to correctly match the head unit to the amplifier.
~ ~ Installati on _.l _.l ~ ~ 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 as you did for the power. Secure the ground cable to the appropriate ground point using a bolt. star washer and nut. Spread silicon over the screw and bare metal to prevent rust. Now its time to connect the power and ground cables to the amplifier. Cut both cables to length. Crimp the yellow spade connectors supplied to the power and ground. Use a hex type screwdriver to loosen the +12V and the GND connections on the amplifier. Terminate the ground first.
