1.0. Wiring Follow the wiring diagram above.
The red ACC wire is designed as the trigger to turn the radio on. It recommended that this wire is connected to an
on/off switch for purposes of lowering the current draw on the battery while the radio is not in use.
Both red ACC and yellow battery wires must be connected to 12V+ for the radio to turn on.
Ground (black) must be connected to a good 12V- source. Best source is directly to the battery.
Speaker wires must be installed to the individual speaker's terminals as labeled, positive and negative, respectively.
Do NOT combine any speaker wires as this will cause permanent damage to the radio's output IC. Tape off any unused
speaker wires individually to prevent accidental shorting which can also harm the output IC.
Antenna must be installed.
Blue wire, labeled "AUTO ANT" is a remote wire for powered antennas/amplifiers/subwoofers.
Rear/front line outputs are low level outputs with right/left and front/rear fade controls. This is for an output like an
amplifier or subwoofer.
Remote control cable is a 13 pin DIN style cable designed for wired remotes (see compatible products on the next
page.
AUX inputs are female RCA connectors for use with input devices. The stereo will NOT control any of these devices,
but they will be heard through the stereo.
Sirius cable is designed for use with a Sirius Tuner (see next page).
