Connecting the Outputs, Testing the Amplifier

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.
