User manual ALPINE MRV-F352

[. . . ] When connecting the MRV-F352 to the fuse box, make sure the fuse for the intended circuit of the MRV-F352 has the appropriate amperage. The MRV-F352 uses female RCA-type jacks for connection to other units (e. Due to the high power output of the MRV-F352, 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. [. . . ] ⷠYour Alpine dealer knows best about noise prevention measures so consult your dealer for further information. 1 RCA Subwoofer Input Jacks (CH5) 2 , 3 RCA Input Jacks (CH3/4), (CH1/2) Connect these jacks to the line out leads on your head unit using RCA extension cables (sold separately). Be sure to observe correct channel connections; Left to Left, Right to Right, Front to Front and Rear to Rear. NOTE: When the CH1 and CH3 are used, the unit automatically enters the mono mode, and when CH1 ­ CH4 are used, the unit enters the stereo mode. 4 Subwoofer Output Terminals (CH5) 5 , 6 Speaker Output Terminals (CH1/2) , (CH3/4) The MRV-F352 has two sets of speaker outputs. Do not use the speaker (­) terminals as a common lead between the left and right channels. 7 Battery Lead Terminal 8 Remote Turn-on Lead Terminal 9 Ground Lead Terminal - Insulation Tube a Battery Lead (Yellow) (Sold Separately) Be sure to add a 50 amp fuse (or two 25A 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. B 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. C 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. Cautions on wire lead connections In case of using the lead (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. 4) Before making this connection, dress a short-circuit prevention rubber tube to the leads. [. . . ] The head unit's power antenna lead is activated only when the radio is on (turns off in the tape or CD Mode). 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-F352 must be connected to a switched power source (ignition) in the vehicle. Using this connection method, the MRVF352 will turn on and stay on as long as the ignition switch is on. [. . . ]
