Amplifier Instruction Manual

SPEAKER CONNECTIONS (QCA4400)
Make the speaker connections using speaker wire that is at least 16
gauge or heavier.
As with any audio component, proper phasing of the amplifier and speakers is essential for
strong bass response. When connecting, make sure that positive (+) from the amplifier is
connected to the positive (+) of the speaker, and the same for negative (-).
***CAUTION! In the bridged mode, the amplifier must see a 4 Ohm load or higher. Any
lower than 4 ohms will cause the amplifier to overheat and possible cause permanent
damage to the amplifier!
REMOTE BASS CONTROL MODULE (OPTIONAL)
(QCA2500D QCA3500D QCA4500D)
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.
