CAUTION: QBASS PLUSTM should only be used in systems with a strong subwoofer section. +18dB is a tremendous amount of bass boost and may damage your speakers or create excessive distortion if abused.

The optional QBASS REMOTETM: This boost control can be mounted in the dash and will supersede the boost control on the endplate.

These PrecisionPower amplifiers no longer need an optional QPORTTM to connect multiple QBASS PLUSTM equipped amplifiers while using one QBASS REMOTETM. The new QBASS PLUSTM circuitry in these amplifiers is now positioned before the crossover circuit. In doing this, Precision PowerTM engineers have allowed you to daisy chain your RCA output to the next amplifier input, causing the first amplifier’s QBASS REMOTETM to become the master control amplifier. See your authorized Precision PowerTM dealer for more information!
