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  SPA1000D,  SPA1300D  ,  SPA1600D  and  SPA1900D  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.
