3. Connect one stripped end of the speaker cable coming from the amplifier to the
RS8Si connection cable’s red wire of one cable and the RS8Si connection cable’s
yellow wire. To connect the three wires, twist the stripped ends of the wire
together and screw down the wire nut on the twisted wires. The material inside
the wire nut will protect the stripped ends of the wire. However, if added
protection is desired, place a large amount of silicon sealant so the bottom of the
wire nut is encased and sealed. Pay attention to the markings on the speaker
cable. Each loudspeaker you connect must be connected to the amplifier’s
speaker wire in the same way.
4. Repeat step 3 with the
RS8Si connection cable’s black wires and the other
stripped amplifier speaker cable’s conductor.
5. Connect the opposite end of the speaker cable to the amplifier or receiver. Start
by performing step 1 and 2 on the speaker cable near the amplifier. Paying
attention to the markings on the speaker cable conductor, attach the same
conductor you attached to the red loudspeaker wire to the positive (red) or (+)
amplifier output terminal. Attach the other conductor to the amplifier’s negative
(black) or (–) amplifier output terminal.
Speaker Phase
Speaker wire has two conductors. One conductor is attached to the negative (black)
or (-) terminals and one conductor is attached to the positive (red) or (+) terminals of
both the loudspeaker and the amplifier. Usually, the wire is marked for your
convenience. There are different ways to mark the conductor; a stripe on one wire, a
ribbed area on one conductor that you can feel, different color metal conductor wire
inside the insulation, the insulation covering the conductor might be different colors,
or there might be a fabric string wound onto one of the conductors. Of course some
cables make it difficult to determine which conductor is which. Be careful to avoid
mistakes. If you do, one loudspeaker will be playing out of “phase” with the other
loudspeaker. An out of phase pair of speakers work against each other and the sound
of the two speakers playing together will be lacking in bass response and have a
“phasey” sound quality. If you suspect the sound is not right, check to make sure that
the conductors on each loudspeaker are attached the same on the loudspeaker and
the amplifier. If you cannot see any markings or determine if they are all attached the
same, try this simple test:
In one-speaker stereo mode
1. Play some music with the amplifier or receiver set to Mono.
2. Stand in the middle of each speaker and three feet away from it. Listen to the
richness of the bass and the loudness of the sound.
3. Turn off the amplifier and reverse the connections on one side of the speaker only.
4. Repeat the listening test with the same setting of the volume controls. If the current
sound has a richer bass and is slightly louder than the previous sound, the speakers
