Note: Speaker wires are usually color-coded or otherwise marked to
indicate polarity. Be sure to connect the wire from the amplifier's
+ (positive) output to the speaker's + terminal, and the amplifier's
- (negative) output to the speaker's - terminal. If you reverse
these connections, bass response is greatly reduced.
Follow these steps to connect your speakers to your amplifier or equalizer/
booster.
1. Connect the amplifier to your stereo system as described in your
amplifier and autosound system's owner's manuals.
2. Cut the speaker cable to the necessary length and separate the wires
about 4 inches on each end.
3. Strip about 1/2 inch of insulation from the wire ends and twist the
wire ends.
4. Connect the speaker wires to the amplifier's output terminals.
5. For each speaker wire, hold down one of the speaker's grooved INPUT
terminal tabs and insert a speaker wire's bare end into the hole
(connecting + to + and - to -). Then release the terminal tab.
