High-Level Inputs
If your vehicle's autosound system does not have phono-type output jacks,
connect its left and right speaker output wires to the amplifier's HIGH
INPUT corresponding L and R terminals, see illustration in Faxback Doc.
#18004.
NOTES: Be sure to connect the terminals +to+ and -to-.
If the autosound system has only three wires, connect the common
speaker wire to both of the amplifier's L and R negative (-)
terminals, see illustration in Faxback Doc #18004.
CONNECTING THE OUTPUTS
Using 18-gauge stranded speaker wire (such as Radio Shack Cat. No. 278-
1217, not supplied), connect the autosound system's left and right speakers
to the amplifier's corresponding left and right SPEAKER terminals, see
illustration in Faxback Doc. #18004.
1. Disconnect the left speaker's positive (+) wire from your autosound
system and reconnect it to the amplifier's left positive (+) SPEAKER
terminal.
Note: The positive wire's insulator might be marked with a positive
(+) symbol, a ridge, or a white stripe, or the conductor wire strands
might be gold colored.
2. Disconnect the left speaker's negative (-) wire from your autosound
system and reconnect it to the amplifier's left negative (-) SPEAKER
terminal.
Note: The negative wire's insulator might be marked with a negative
symbol (-) or the conductor wire strands might be silver colored.
3. Repeat Steps 1 and 2 to connect the right speaker to the amplifier's
right SPEAKER terminals.
TESTING THE AMPLIFIER
1. Temporarily reconnect your vehicle battery's negative (-) cable.
2. Turn on your vehicle's ignition and verify that both the amplifier and
your autosound system work properly.
