Bridgeable & Tri-Mode Operation Memphis Car Audio Power Reference amplifiers can be used in stereo, bridged, or tri-mode operation. Tri-Mode operation means that a pair of speakers are wired in the conventional stereo manner, while a subwoofer is simultaneously connected to the bridged terminals of the same two channels. This is useful for simple 2- range speakers.
INSTALLATION Professional installation by an authorized Memphis Car Audio dealer is highly recommended! Otherwise, the performance of your new gear may not be satisfactory. In the event that you decide to do your own installation, please read and follow this manual very carefully. Failure to do so may compromise the integrity of this product, your automobile, and possibly void the product warranty.

POWER SUPPLY CONNECTIONS WARNING! INSTALL THE FUSE AT THE BATTERY LAST! Use conventional stranded copper wire for all connections. Finish the ends of the wires at the amp and vehicle connection with the proper size terminals. Poorly made connections, and /or inadequate wire size will generate excessive heat and may lead to equipment failure. The 12 VOLT + connection should be made directly at the positive battery post, using the wire size recommended below, and fused within "18"of the battery.
SIGNAL INPUT CONNECTIONS The RCA jack(s) marked 'IN' should be connected to the low level outputs of your source unit or signal processor. High-level (speaker level) inputs are provided as well. L CH (+) WHITE R CH (+) GRAY CHASSIS GROUND BLACK PR 2.50 SPEAKER POWER...

SET UP AND ADJUSTMENT Gain The gain control is NOT a volume control. The gain control adjusts the amount of signal required to drive the amplifier to full output. With the gain at maximum (full clockwise rotation), less signal voltage is required to drive the amp to full output. With the gain at minimum (full counter-clockwise rotation), more signal voltage is required to drive the amp to full output.
FEATURES AND CONTROLS TROUBLESHOOTING Before removing your amplifier, refer to the list below and follow suggested procedures. Speakers and their wires should be tested first. No Output: a. Confirm that all terminal strip connections are firmly connected. b. Check in-line and built-in fuses. Both "12V"and "RMT" terminals must have +12 Volts to chassis ground.
