Alpine alpine owner manual USE the Correct Ampere Rating When Replacing Fuses

Speaker Output Terminals

•The speaker output terminals of this unit are insert terminal.

Be sure to observe correct speaker output connections and polarity in relation to the other speakers in the system. Connect the positive output to the positive speaker terminal and the negative to negative.

About Subwoofer Input/Output Terminals

•The input is stereo but the output is monaural.

•Reversing subwoofer polarity may be desirable in some installations for optimum bass performance.

About Bridged Connections

In the bridged mode, connect the left positive to the positive terminal on the speaker and the right negative to the negative terminal of the speaker. Do not use the speaker (–) terminals as a common lead between the left and right channels.

Use a Y-adapter (sold separately) for the input when bridging the outputs. (Refer to the “BRIDGED CONNECTIONS” on page 13.)

NOTE:

•Do not connect the speaker (–) terminal to the vehicle’s chassis.

RCA Input Jacks

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 and Right to Right.

USE THE CORRECT AMPERE RATING WHEN REPLACING FUSES.

Failure to do so may result in fire or electric shock.

Power Supply Terminal

Remote Bass Control (Option)

Connect the Remote Bass Control Unit (sold separately) to adjust the output level remotely. This is not to replace appropriate gain level setting between the amplifier and head unit.

Battery Lead (Sold Separately)

Be sure to add an in-line fuse with the battery lead 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. See below for appropriate fuse value and minimum wire gauge requirement:

PDR-V75 ..................... 80 amp fuse, 4 AWG/21 mm2

Ground Lead (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 while keeping wire length as short as possible.

Minimum required wire gauge for this connection is as follows:

Remote Turn-On Lead (Sold Separately) Connect this lead to the remote turn-on (positive trigger, (+) 12V only) lead of your head unit. If a remote turn-on lead is not available, see “CONNECTION CHECK LIST” section on

page 8 for alternative method.

NOTE:

•When connecting the speaker output leads of the head unit to this unit with an RCA extension cable (sold separately), etc., you do not need to connect the remote turn-on lead, owing to the “REMOTE SENSING” function of this unit. However, the “REMOTE SENSING” function may not work depending on the signal source connected. In such a case, connect the remote turn-on lead to an incoming power supply cord (accessory power) in the ACC position.
