CAUTION: CAUTION: If you feel unsure about installing this system yourself, have it installed by a authorized MB Quart Dealer. Before installation, disconnect the battery negative (-) terminal to prevent damage to the unit, fire and/or possible injury. Before beginning any installation, follow these simple rules: 1. Be sure to carefully read and understand the instructions before attempting to install the unit. For safety, disconnect the negative lead from the battery prior to beginning the installation. For easier assembly, we suggest you run all wires prior to mounting your unit in place. Route all of the RCA cables close together and away from any high current wires. Use high quality connectors for a reliable installation and to minimize signal or power loss. Before installation, disconnect the battery negative (-) terminal to prevent damage to the unit, fire and/or possible injury. Avoid running power wires near the low level input cables, antenna, power leads, sensitive equipment or harnesses. The power wires carry substantial current and could induce noise into the audio system. Keep RCA cables close together but isolated from the amplifier's power cables and any high power auto accessories, especially electric motors. This is done to prevent coupling the noise from radiated electrical fields into the audio signal. When feeding the wires through the firewall or any metal barrier, protect them with plastic or rubber grommets to prevent short circuits. Leave the wires long at this point to adjust for a precise fit at a later time. Remove the four (4) 8/32 allen head screws holding the connection end cover in place (this is the end without the vents for the fans). Keep the cover and screws in a safe place for reinstallation when mounting and wiring is complete. Prepare the RED wire (power cable) by stripping 1/2" of insulation from the end of the wire. Strip 1/2" from the battery end of the power cable and crimp a large ring terminal to the cable. [. . . ] While the Front End Bypass is turned on, all adjustments made to the gain or crossover will be bypassed. Do the following individually for each channel. filter Switch Placing the switch in the ON position (In Position) sets the amplifier to the All Pass mode , preventing any crossover adjustment , allowing all frequencies to pass.
