Memphis MXA480.4M Manual page 9

Speaker have a positive and negative marking on the terminals. These are used to indicate polarity and must
be considered when wiring speakers or subwoofers to an amplifier. Amplifiers also have positive and
negative markings on their speaker outputs. Use these marking to match polarities to ensure the speakers
are in phase. Failure to wire speakers or woofers in phase with one another will result in a loss of bass. All
MXA amplifiers require a minimum 2ohm impedance in stereo or 4 ohms in mono (bridged) mode.
Always check your speaker load with a multi-meter before hooking them up to the amplifier. The
MXA480.4M amplifier is stable to 2 ohms stereo or 4 ohms bridged mono. The MXA850.5M
amplifiers are stable to 2 ohms stereo or 4 ohms bridged mono (front & rear channels) and stable
CAUTION
to 1 ohms (sub channel). The MXA600.1M is 1 Stable. Any Impedance (load) smaller than what
is recommended will damage the amplifier! Such damage is not covered under warranty, so pay strict
attention to what connections are made to the amplifier.
