User manual ALPINE PDX-M6

[. . . ] When drilling holes in the chassis for installation, take precautions so as not to contact, damage or obstruct pipes, fuel lines, tanks or electrical wiring. Bolts or nuts used for the brake or steering systems (or any other safety-related system), or tanks should NEVER be used for installations or ground connections. Using such parts could disable control of the vehicle and cause fire etc. Return it to your authorized Alpine dealer or the nearest Alpine Service Center for repairing. [. . . ] Be sure this is a good ground by checking continuity to the battery (­) terminal. Remove the Top Cover by inserting a flat-tipped instrument (such as a panel removal tool or slotted screwdriver) into the 2 notches of the unit (marked A). If removal is still not possible, bend the Top Cover and remove the tabs on both sides. Fasten the unit down with the four self-tapping screws (M4 x 36, supplied). Attach the Stacking Plates (Supplied) on the first unit with Machine Screws M3 x 7 (Supplied). Next, install the third unit as described for the second unit in B above. Before making connections, be sure to turn the power off to all audio components. Connect the yellow battery lead from the amp directly to the positive (+) terminal of the vehicle's battery. If you make this connection yourself, ensure the connection is correct by following the instructions below carefully. To prevent disconnection of the leads or dropping of the unit, do not carry the unit by the wire. 4AWG/21 mm2 is the minimum power and ground cable size that should be used to connect this amplifier. The length of these cables should not exceed 1 m to assure safe operation. If the length of the power and ground cables exceed 1 m, or if you connect more than one amplifier, a power distribution block should be used with 2AWG or 1/0AWG/33 mm2 or 53 mm2 power and ground cables depending on the length necessary. If in doubt, consult your dealer or Customer Support regarding correct wire gauge to use. Strip back between 7-10 mm (9/32"-3/8") of the power wire's insulation to expose the conductor. notes: · If the length of the exposed conductor is too short, a poor connection may occur causing operation failure or sound interruption. Conversely, if the exposed conductor is too long, an electrical short-circuit may occur. Loosen the unit's wire terminal hexagon screws, and insert the exposed conductor into the terminal and finally tighten to secure the connection. D Unité de commande des graves à distance (en option) Raccordez l'unité de commande des graves à distance (vendue séparément) pour régler le niveau de sortie de l'unité principale et le niveau de gain d'entrée de l'unité. Keep electrically conductive objects away from the unit's terminals/parts (power terminals, fuses, speaker output terminals, RCA connectors, etc. Locate the unit and route the leads at least 10 cm (3-15/16") away from the car harness. Keep the battery power leads as far away from other leads as possible. [. . . ] Ground all your audio components to the same point on the chassis to prevent ground loops. When making adjustments 12-15 below, remove the hexagon screw (indicated by in the illustration) using the hexagon wrench (small, supplied), and then open the control cover. N Subsonic Filter Mode Selector Switch a) Set this switch to "OFF" in order to hear (or feel) the lowest frequencies available. L Input Gain Selector Switch Set this switch according to the head unit's output level. [. . . ]
