5 When both speaker wires are connected to the terminal block using the high-power bridge cover, insert the
assembled terminal block into the appropriate ZONE port on the amplifier to complete the subwoofer
connection for the zone.
6 Repeat the previous steps for additional subwoofers.
7 Connect a single RCA cable to the RCA subwoofer out connector from the stereo for a zone you want to use
with the subwoofer.
8 Connect the single RCA connector from the stereo to the open RCA connector for the channels powering
the subwoofer.
9 Repeat steps 7 and 8 for additional subwoofers.
Speaker Wire Gauge Guide
When connecting speakers, you should use 16 AWG (1.31mm
2
) copper-coated aluminum speaker wire for most
installations.
When connecting a subwoofer, you should use 14 AWG (2.08 mm
2
) copper-coated aluminum speaker wire for
most installations.
You can use these tables to determine if you need to use a larger gauge of wire. These tables account for
terminal connection resistance.

NOTE: If you are using pure copper wire instead of copper-coated aluminum, you can use smaller-diameter
(larger gauge number) wire because of the increased material conductivity.
