Alpine 3555 - Remote Turn-On Lead Wiring Options

CONNECTIONS |
Please check your head unit for the conditions listed below:
a. The head unit does not have a remote turn-on or power antenna lead.
b. The head unit's Power antenna lead is activated only when the radio is on (turns off in
the tape or CD Mode).
c. 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 3555 must be connected to a switched power source
(ignition) in the vehicle. Be sure to use a 3A fuse as close as possible to this ignition
tap. Using this connection method, the 3555 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 3555 turn-on lead. This switch will
then be used to turn on (and off) the 3555. Therefore, the switch should be mounted so
that is accessible by the driver. Make sure the switch is turned off when the vehicle is not
running. Otherwise, the amplifier will remain on and drain the battery.
