Connecting the Subwoofer
There are several different ways to connect the subwoofer. The method you choose is
primarily determined by the presence of a dedicated subwoofer output on your
amplifier/receiver. The connection methods are presented in order of preference.
Connecting to a Dedicated Subwoofer Output
A dedicated subwoofer output is usually one or two RCA jacks marked "Subwoofer",
"Sub Pre Out", or something similar on the back of the amplifier/receiver. Refer to
the manufacturer's documentation for reference. Subwoofer outputs are
monophonic, so if you have two subwoofer outputs they are intended to drive two
separate subwoofers.
To make this connection you will need a cable with a single RCA plug on one end,
which splits into two RCA plugs on the other end. This can be either a single cable
or a cable combined with a splitter.
1.
Insert the two RCA plugs at the one end of the cable into the two RCA input
jacks on the back of the subwoofer. Because the signal is a mono signal split
into two outputs, there are no polarity issues to worry about.
2.
Insert the single RCA plug at the other end of the cable into the subwoofer
output jack on the back of the amplifier/receiver.
Connecting to a Stereo Preamplifier Output
If your amplifier/receiver lacks a dedicated line level subwoofer output, the next
best option for connecting the subwoofer is to use line level preamplifier outputs.
These outputs should not be confused with line level outputs intended to connect
components, such as tape decks or DVD recorders, to the amp. Preamplifier outputs
will usually be marked as "Pre-amp Out" or something similar. Refer to your amp's
owner's manual to determine which, if any, outputs are for the pre-amp outputs.
