Frequently Asked Questions - Stadium Marine 102 JBL

How do I wire the speaker signal?

Connect the positive (+) and negative (-) speaker wires to the appropriate outputs of your source unit or amplifier, observing proper polarity.

How do I connect the LED lights?

Plug the 24-gauge black (+), blue, green, and red LED wires into the included female connector, then run to a 12V power source or light controller. For direct wiring, connect black to positive and any combination of R, G, B wires to negative to produce different colors.

What colors can the LEDs produce?

Seven colors: Red, Green, Blue, Yellow (R+G), Purple (R+B), Aquamarine (B+G), and White (R+G+B) depending on wire connections.

What is the recommended enclosure for the Stadium Marine 102?

For sealed box, use 2-4 ft³; for vented box, use 2-4 ft³ with a 100mm diameter port. Tuning frequencies vary with volume (see manual).

Can I use this subwoofer with a 2-ohm or 4-ohm amplifier?

Yes, it has a switch to select 2-ohm or 4-ohm impedance to match your amplifier.

Is this subwoofer suitable for marine use?

Yes, it is designed with marine-grade materials to withstand moisture and splashes, but proper installation with foam seal is recommended.

How do I mount the subwoofer?

Use the included screws and speed clips if needed. Apply the self-adhesive foam seal to the frame for waterproofing and acoustic seal. Be careful with fiberglass to avoid cracks.

What is the power handling of this subwoofer?

Continuous 300W, peak 900W.

How do I maintain the subwoofer?

Clean with a soft cloth; do not use harsh chemicals. Ensure connections are tight and free from corrosion. Check foam seal periodically.

Can I use multiple subwoofers together?

Due to low impedance, do not wire two or more in parallel to an amplifier to avoid overheating and damage. Use series connections or separate amplifier channels.

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.
