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.
