  • Dimensions: 368.3 x 279.4 x 144.2 mm

Bluetooth Antenna Connection

Connect the Bluetooth Halo Aerial Technology Antenna (AQ-BTANT-1) to the male SMA connector. Do not apply excessive torque on the SMA connector (no more than 0.5N-m). Use hands to tighten the connection (do not use a wrench). To ensure that the range is maximized, make sure the arrow is pointing directly upward toward the sky when the antenna is mounted. If there is excess antenna cable length make sure this is coiled and not bent as bending it may cause damage to the cable. For spa or hot tub installation, the antenna should be located above the waterline otherwise Bluetooth range could be drastically reduced.

1. Connect the Bluetooth Antenna’s cable to the Halo Aerial Technology connector on the control panel, ensuring it is fully secure by turning clockwise until it is finger tight.

2. Make sure the arrow is pointing directly upward toward the sky when the antenna is mounted to ensure the Bluetooth range is maximized.

3. Screw on the provided Bluetooth Antenna and avoid bending the cable at more than a 60° angle. If there is no suitable surface to screw it into, we recommend using a quality double-sided tape.


The SWA6+ Combined Stereo Subwoofer’s power can be reduced or increased to suit different applications. An output level of -3dB or -6dB should be used to avoid blowing out very small speakers, often used in spa applications. By cutting only the white wire the output level will decrease to -6dB below the nominal 0dB. By cutting both the white and black wires the power/volume will increase to +6dB above the nominal 0dB. By cutting only the black wire the power/volume will increase from -3dB to the nominal 0dB. These modifications should only be carried out by an experienced audio installer.

Power On

The SWA6+ requires +12V DC to both the red and yellow wires. When both of these wires have power the SWA6+ is always powered on, and the green "Power On" LED will remain illuminated. Ground is connected to the black wire. In a spa application this requires the red and yellow wires to be jumped together and then connected to the +12VDC output of the power source. In this set up, the SWA6+ will always be on, with a very low current draw when idle. In a boat, ATV, or other application requiring power from a battery, the yellow wire (constant power) should be connected to the battery, and the red wire should be connected to the ignition or a switch.

Frequently Asked Questions

Q1. I am about to install the subwoofer. What do you recommend?

To install the subwoofer in a wood environment, use soft fabrics around it for the best sound.

Q2. Does it have an internal amplifier?

Yes, it does. The built-in amplifier is 288 Watt [Power (max): 72W x 2 (@ 2 Ohms) / 45W x 2 (@4 Ohms)].

Q3. Can I connect an external amplifier to the subwoofer?

Yes, you can. Make sure the amplifier has RCA cables. If the external amplifier does not have RCA cables it will not connect to the subwoofer. In this scenario, the subwoofer will connect to the amplifier, and the amplifier will connect to the speakers as follows: subwoofer > external amplifier > speakers. This will give you the best sound possible for this setup.

Q4. I lost my remote control. Where can I buy new one?

You can purchase a new remote control from Aquatic AV online. The remote control that is compatible with SWA6+ Combined Stereo and Subwoofer is the RF6 Remote.

Q5. How do I access the AUX mode?

If you have a device plugged into the AUX input (RCA input), and you do not have any other inputs currently active, your subwoofer should default to the AUX mode. If you have a device currently paired via Bluetooth to your subwoofer, you will be unable to access the AUX unless you either disconnect from Bluetooth or switch the modes using a 6-series remote (sold separately).

Q6. Can I use my SWA6+ Combined Stereo and Subwoofer by itself? Do I need more speakers?

Yes, you can use the SWA6+ by itself. Your all-in-one active subwoofer comes with a 288-watt amplifier built into the unit. You do not require additional speakers to play music from the device. However, adding speakers may improve the overall sound quality.

Q7. What is the difference between the SWA6 and the SWA6+?

The SWA6+ has more features compared to the SWA6, including FM radio, USB streaming, and a wireless remote control.
