SIGNAL CONNECTIONS
Connect the RCA output of the head unit (AM/FM cassette player, CD, or DAT) to the
RCA input terminals of the amplifier.
To make these connections, we recommend high quality RCA cables, which are available
at your local car audio retailer. Run signal wires away from electrical wires to avoid
possibility of induced noise from the car’s electrical system (i.e. popping noises or engine
noise).
SPEAKER CONNECTIONS
IMPORTANT! The following speaker connection are for the amplifier in normal mono
configuration.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 (-).
Please note that although the QCA2500D , QCA3500D , QCA4500D are mono amplifiers,
we have provided two sets of speaker terminals on the amplifier. These terminals are
connected in paralleled internally (connected together). The second set of speaker terminals
are intended for ease of connection when running multiple woofers.
