User manual ALPINE MRP-T220

[. . . ] Always stop the vehicle in a safe location before performing these functions. Doing so may result in an accident, fire or electric shock. Use for other than its designed application may result in fire, electric shock or other injury. Doing so may cause heat to build up inside and may result in fire. [. . . ] Connect the yellow battery lead from the amp directly to the positive (+) terminal of the vehicle's battery. Do not connect this lead to the fuse block. Locate the unit and route the leads at least 10 cm away from the car harness. ⷠKeep the battery power leads as far away from other leads as possible. ⷠConnect the ground lead securely to a bare metal spot (remove any paint or grease if necessary) of the car chassis. ⷠIf you add an optional noise suppressor, connect it as far away from the unit as possible. Your Alpine dealer carries various noise suppressors, contact them for further information. ⷠYour Alpine dealer knows best about noise prevention measures so consult your dealer for further information. 1 Speaker Output Terminals The MRP-F240/MRP-T220 has two sets of speaker outputs. Be sure to observe correct speaker output connections and phasing. Do not use the speaker (­) terminals as a common lead between the left and right channels. Do not connect this lead to the vehicle's chassis. Do not connect speaker leads together or to chassis ground. Use a Y-adaptor (sold separately) for the input when bridging the outputs. 3 Ground Lead (Black) (Sold Separately) Connect this lead securely to a clean, bare metal spot on the vehicle's chassis. Verify this point to be a true ground by checking for continuity between that point and the negative (­) terminal of the vehicle's battery. Ground all your audio components to the same point on the chassis to prevent ground loops. 4 Remote Turn-On Lead (Blue/White) (Sold Separately) Connect this lead to the remote turn-on or power antenna (positive trigger, (+) 12V only) lead of your head unit. 5 Battery Lead (Yellow) (Sold Separately) Be sure to add a #25 amp fuse as close as possible to the battery's positive (+) terminal. This fuse will protect your vehicle's electrical system in case of a short circuit. If you need to extend this lead, the wire gauge should be 8 AWG or larger. This is an ideal output for driving a separate subwoofer amp. [. . . ] The full frequency bandwidth will be output to the speakers with no high or low frequency attenuation. 20 Bass EQ Adjustment Knob Adjust the low frequency to your favorite level between 0dB to +12dB. # Use either RCA line level or speaker level inputs.
