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 pair of speakers is 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-channel systems that require a subwoofer in addition to the full-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.

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.

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.

SPEAKER CONNECTIONS 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.

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.

Bass Boost Bass boost on all models is switchblade either on or off. Boost on the 300.2 is variable. Boost should be used with discretion, keeping in mind that electronically enhanced boost places an additional load on the amplifier and the speakers they are connected to.

Speaker and input wires should not be routed next to wires that interconnect lights and other accessories/equipment. d. If above steps do not improve/clear noise interference, the system should be checked by your Authorized Memphis Car Audio dealer.
