REMOTE BASS CONTROL MODULE (QS1500D)
Before connecting the remote, it will be necessary to find a mounting location that will be
easy to access for adjustment. Once you select your mounting location, you will need to
run the control wire from the remote to the amplifier. To avoid possibility of induced noise
from the car's electrical system (i.e. popping noises or engine noise), run the cable from
the remote to the amplifier away from the car's electrical wiring.
Subsonic Filter - On the QS1500D a subsonic filter has been
provided to filter out unwanted subsonic bass frequencies
below the audible range of the subwoofer . This feature helps
to improve the amplifiers overall performance since power
is not wasted reproducing frequencies beyond the speakers
operating range. This feature works in conjunction with the
Low-pass crossover to provide band-pass filtering.
