Custom Autosound USA-630II second series - Manual (Page 5)

Power and Speaker Connections (Refer to Wiring Diagram on page 5.)
A-Main Power-Red Wire B+
Connect the RED wire (B+) to an accessory fuse that is switched OFF when
the key switch is in the OFF position and is switched ON when the key switch
is switched to the ON or accessory position.
B-Memory Back-Up-Orange Wire B+
Connect the orange wire (memory B+) to an accessory fuse that is always
ON regardless of the position of the key switch.The lead supplies power to the
program memory and the clock circuit when the USA-630 is switched off.(This
does not apply to cars with 6volt system)
C-Power Antenna (Auto-Antenna) - Yellow Wire
This wire can be connected to the positive switch terminal of the relay for the
auto antenna (if your car is equipped )or to the remote on switch of the ampli-
fier or booster (if equipped). NOTE:DO NOT connect this wire to a negative
position or to any device that requires high current Otherwise the radio may
fail or become "fried". If your car is not equipped with an auto antenna,leave
this wire sealed and do not allow it to short to any other positions.
D - Ground Wire - Black
Connect the black ground wire to any clean paint and contaminant free area
of vehicle chassis.
NOTE: Proper grounding is essential for optimum performance of your radio.
E - Speaker Wires
Connect the speaker wires as shown in Figure 1.
Low Level Output (Line Out Jacks) Connection
The USA-630 is equipped with low level, high impedance outputs. The low
level outputs (RCA type Line Out Jack) will not drive speakers. If you are con-
necting an amplifier or plan on it in the future, it is recommended to use these
leads. It makes for a cleaner and easier Installation.
