User manual ALPINE MRV-1002

[. . . ] When connecting the MRV-1002/MRV-T502/MRV-T302 to the fuse box, make sure the fuse for the intended circuit of the MRV-1002/MRV-T502/MRV-T302 has the appropriate amperage. The MRV-1002/MRV-T502/MRV-T302 uses female RCA-type jacks for connection to other units (e. Due to the high power output of the MRV-1002/MRV-T502/MRV-T302, it is important that all connections are clean and well secured, or damage could result. When installation and connections are completed, check the followings: a) Connections are proper. [. . . ] 2 Speaker Output Terminals The MRV-1002/MRV-T502/MRV-T302 has two sets of speaker outputs. Do not use the speaker (­) terminals as a common lead between the left and right channels. 3 Battery Lead (Yellow) (Sold Separately) Be sure to add a 5 60 amp fuse (or two 30A fuses in parallel) 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. 20 amp fuse 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 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. 6 Insulation Tube 7 Speaker Input Leads These leads are input leads for use with head units not equipped with preamp outputs. When not using the RCA Line Input connectors, you should connect these wires to the speaker output leads of your head unit. The MRV-1002/MRVT502/MRV-T302 accepts input from high power or standard power head units. - Right Speaker a White (+) b Black (­) c Gray (+) NOTE: In case of using the speaker input cord, noises may occur at power off depending on the head unit connected. If you feel uneasy about the noises, add a SPST switch to the connection. 5) Cautions on wire lead connections In case of using the leads (speaker/power supply cord) purchased at the market, use the hexagon screws and the hexagon wrench included as the accessory to make connection easier. Improper handling may cause troubles, so make the connections correctly by referring to the description shown below. A special care will be necessary for the connections using the hexagon screws, so we recommend you to ask the connection for your dealer. If the wire size used is unknown, ask to the shop you get the unit, service shop, Alpine Service Center, etc. ) of the wire leads by about 7 ­ 10mm (9/32" ­ 3/ 8") from the lead end to exposure the conduction leads. If length of the conduction leads with the cover removed is too short, incorrect connection may occur and this may cause operation failure or sound interruption. On the other hand, if the length is too long, an electrical short-circuit may occur. Tighten the hexagon screw with the hexagon wrench, and the lead will be fixed. [. . . ] The head unit's power antenna lead is logic level output (+) 5V, negative trigger (grounding type), or cannot sustain (+) 12V when connected to other equipment in addition to the vehicle's power antenna. If any of the above conditions exist, the remote turn-on lead of your MRV-1002/MRVT502/MRV-T302 must be connected to a switched power source (ignition) in the vehicle. Using this connection method, the MRV-1002/MRV-T502/MRV-T302 will turn on and stay on as long as the ignition switch is on. If this is objectionable, a SPST (Single Pole, Single Throw) switch, in addition to the 3A fuse mentioned above, may be installed in-line on the MRV-1002/MRV-T502/MRV-T302 turnon lead. [. . . ]
