User manual ALPINE MRD-M300

[. . . ] CAUTION: These controls are for tuning your system. please consult your authorized Dealer for adjustment. This symbol means important instructions. WARNING Failure to heed them can result in serious injury or death. [. . . ] ⷠIf you tighten the screw to fix the power supply wire on the unit after the power supply connection is completed, the tool may touch the unit and may cause a short-circuit. ⷠBe sure not to allow the power supply wire to be exposed outside the terminal. ⷠFix the power supply wire securely to prevent disconnection or dropping. G When tightening the screw to fix the power supply wire, be sure not to touch the tool to the unit. Due to the high power output of the MRD-M1005/ MRD-M300, considerable heat is produced when the amplifier is in operation. For this reason, the amplifier should be mounted in a location which will allow for free circulation of air, such as inside the trunk. Using the amplifier as a template, mark the four screw locations. Make sure there are no objects behind the surface that may become damaged during drilling. Position the MRD-M1005/MRD-M300 over the screw holes, and secure with four self-tapping screws. NOTE: To securely connect the ground lead, use an already installed screw on the metal part of the vehicle (marked (#)). Be sure this is a good ground by checking continuity to the battery (­) terminal. If you are in doubt about how to make this connection, consult your dealer. Wire Size (Battery Lead, Ground Lead) Recommended wire size for this unit is 21mm2 ­ 8mm2 . ⷠIf the wire gauge used is unknown, ask your dealer. Remove the insulation from the ends of the wire leads by about 7 ­ 10mm (9/32" ­ 3/8"). If length of the exposed wire is too short, a poor connection may occur causing operation failure or sound interruption. ⷠOn the other hand, if the length is too long, an electrical short-circuit may occur. Turn the screw attached to the terminal. Insert the exposed wire end into the lead terminal. Tighten the hexagon screw with the hex wrench (included), to fix the lead. 8) Before making this connection, use insulated shrink tubing to cover any exposed wire extending beyond the terminal. To prevent disconnection of the leads or dropping of the unit, do not use the cabling to carry the unit. [. . . ] When you finish making adjustments, close the top cover and fix it with the original hexagon screws. When multiple amplifiers are connected to an Amplifier LINK compatible Head Unit, each amp must have its own, unique ID. ⷠWith a single amplifier system, an AMP ID is not necessary. Adjust the input level of the amplifier to match the output of the connected head unit. [. . . ]
