SPEAKER SIGNAL WIRING

To send signal to the JBL marine speaker, connect the positive (+) and negative (-) speaker wires to the appropriate speaker outputs of your source unit or amplifier. Be sure to observe proper polarity.

SPEAKER LED WIRING

To provide power for the LEDs, plug the 24-gauge black (+), blue, green, and red LED wires from the speaker into the included female connector, then run the wires from the female connector to your compatible 12-volt power source or light controller (sold separately). If using a separate controller, be sure to connect each wire to the proper output.

If hardwiring the LEDs directly to your power source, you can choose the color of the LEDs by connecting the black wire to the positive (+) terminal, and the appropriate R, G, and/or B single wire or combination of wires to the negative (-) terminal.

There are 7 possible colors, depending on the wiring configuration you choose:

Wire connected to positive (+12V) terminal	Wire connected to negative (-) terminal	Color produced
Black	Red	Red
	Green	Green
	Blue	Blue
	Red + Green	Yellow
	Red + Blue	Purple
	Blue + Green	Aquamarine
	Red + Blue + Green	White

APPLYING FOAM SEAL

To help seal your installation against water, and to provide an airtight acoustic seal, apply the self-adhesive foam seal to the speaker frame.
