Using the Bass50: Vehicle Kit - AUX Wireless

The AUX Wireless Kit lets you connect your Bass50 to your vehicle’s speakers wirelessly—no DSPs, aftermarket amps, or RCA inputs needed. The setup relies on Bluetooth + SKAA to transmit your phone’s audio to your Bass50, then back to your car’s AUX port for full-system bass enhancement.

What You Need

Before you begin, make sure you have:

• Your Bass50, powered off

• A smartphone with Bluetooth and the Trulli App installed

• The Trulli AUX Wireless Vehicle Kit (includes Trulli Remote with pre-installed CR123A Battery, Trulli AUX Receiver, 3.5mm AUX Cable (12”), 12v To USB Outlet Adapter, and a Dash Mounting Kit with 4 options)

• A vehicle with a 3.5mm AUX input

Note: Using Apple CarPlay or Android Auto?
If your vehicle relies on CarPlay or Android Auto for audio and doesn’t have a physical AUX input, this kit may not be compatible with your current setup. We’re actively developing a new wireless vehicle solution that works seamlessly with CarPlay and Android Auto, launching by the end of the year. In the meantime, you can read the full article here to learn more: My vehicle has Apple CarPlay/Android Auto, can I use the AUX Wireless Vehicle Kit?

How It Works (Signal Flow Explained)

The system looks like this:

1. Your Phone → Bass50 (Bluetooth)

   • Your phone streams audio to the Bass50 over Bluetooth.

2. Bass50 → Trulli Receiver (SKAA Wireless)

   • The Bass50 then transmits a SKAA signal wirelessly to the included Trulli Receiver.

3. Trulli Receiver → Your Vehicle’s AUX Input (Wired)

   • The Receiver plugs into your vehicle’s AUX port and gets power from either a built-in USB port or the included 12V adapter.

4. Optional: Remote Control → App → System

   • The Trulli Remote connects to the Trulli App via Bluetooth, letting you control volume, presets, and bass level without using your phone while driving.

Important: The AUX Wireless Kit only works with vehicles that have a 3.5mm AUX input.

Step-by-Step Setup

1. Install the Trulli App

Download and install the Trulli App from the App Store or Google Play.

Mounting the Remote (Optional)

For easier access, you can mount your Trulli Remote in your vehicle using one of the four included options:

CD Slot Mount Base
With the center lever in the up position, slide the mount base into the CD slot. Secure the base by moving the lever to the down position.

Air Vent Mount Base
Squeeze the rear clip to open and insert into the air vent louvers. Adjust the lower foot to support the base.

Adhesive Mount Base
Remove the protective cover over the adhesive strip, then firmly press the base to the surface.

Magnetic Mount Head:
The magnetic mount head attaches to any of the mount bases in a similar manner:

1. Feed the mount base attachment point through the tightening ring.
2. Insert the attachment point into the back of the magnetic mount head.
3. Adjust the angle as needed, then tighten the ring to secure the mount head.
4. Center the rear of the Trulli Remote on the magnetic mount head to complete the
   installation.

Final Notes

With the AUX Wireless Kit, the Bass50 brings powerful, wireless bass to vehicles that were never designed for aftermarket upgrades—no RCA inputs or DSPs required. Whether you're enhancing a factory stereo or breathing new life into an old rig, this setup delivers a clean, reliable signal path and lets you fine-tune everything from your phone—or your dash.

If you ever change vehicles, reconfigure your setup, or update your system, you can easily re-run the setup in the Trulli App or move your Bass50 to a new ride. It’s that flexible.

Now turn it up and listen out loud.
