Most speakers have a positive (indicated with a + or colored dot) and negative (indicated
with a -) marking on the terminals. These are used to indicate polarity, and must be
considered when wiring stereo speakers or multiple subwoofers to an amplifier. Amplifiers
also have positive and negative markings on their speaker outputs. These may be used to
correspond or match with the speaker polarity markings to ensure that the stereo speakers
are in-phase with each other. Failure to wire stereo speakers in phase with one another will
result in a loss of bass. All Power Reference Class AB amps require a minimum 2ohm
impedance in stereo or 4 ohms in mono (bridged) mode.
