IGNAL 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 possibil-
ity of induced noise from the car’s electrical system (i.e. popping noises or engine noise).

PEAKER 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 BI1750M and BI3000D 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.
