electrical system. The RED wire connected to the back of the NONFACTORY
(aftermarket) radio is commonly a 12 volt switch. The wire has +12 volts when the
car's key is rotated forward to accessory position or when the car's engine is running.
When the car is turned off and key is removed the wire has 0 volts. If your Active
Speaker Box is connected long term, the switch wire will send the proper signal
when to turn off. If you do not have an aftermarket radio you will have to locate an
accessory wire in the vehicles electric system. A multi-meter or testing device will
help identify the correct wire. NOTE: A test light only indicates hot / cold wire, not
voltage. NOT all wires are 12 volt.
3) The ground wire must connect to the vehicles body. The connection point to the
car must be exposed metal free of dust/dirt/grease/paint/primer. Use a flat area,
bolts and suspended locations may not be connected to the frame of the car. Use
self-tapping screws and ring crimp connector to attach the end of the wire securely
to the chassis/body.
4) To gain a sound source from the car's radio you must use audio component wires.
Run the wires from the rear of the NONFACTORY radio to the audio component
inputs (RCA cables) on the active speaker box. If you have a factory radio you will
need a "line out converter". This device will convert your rear speaker wires into a
component audio terminal. Follow the directions provided with the converter.
5) Run the IR Remote control sensor wire from the Active Speaker Box to a location
where the remote control will be used most often (e.g. front dashboard). This will
allow the user to control the SD/USB track selection and volume; or enter FM radio
frequency and change the volume.
6) If you do not want to hard wire the power, a cigarette power plug is
provided. You can use this to simplify the power needs of the Active Speaker Box.
Plug in power plug to the proper location and your Active Speaker Box will have
power. To play music from the car's radio, the audio component wires (RCA cables)
still must be run, reference Step four.
If all connections are properly attached, the Active Speaker Box will play the music
media that is being produced by the car radio. When the car is off, you can
unplug the unit's power harness to remove the Active Speaker Box.
