7 Bass Boost: This is a variable control to increase the bass boost at 45Hz from 0 -+18dB of gain, adjust to suit. 8 Subsonic Filter: This is a variable control filters out all Sub Bass Frequencies below the set point at 18dB/octave. 9 1 2 3 4 5 6 7 8 9 10 11 Level: This allows level adjustment of the input signal. Use this control to correctly match the head unit to the amplifier.
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.
