The mObridge Ford Bronco amplifier kit provides seamless integration with your Ford Bronco’s SYNC 4 infotainment system to enhance your vehicle’s listening experience. This is a Bronco specific kit for our 9 Channel K2 A2B amplifier. This amplifier replaces the factory amp.

This is a full plug and play kit – everything needed to complete the install of the amplifier in your Bronco is included in the kit and no wires need to be cut! The amp comes with a basic tune with crossover points and time alignment set, but this is fully adjustable to suit any aftermarket speakers via our tuning tool mObridge DSP.

Powered by a Blackfin DSP, the mObridge A2B amplifier provides 8.1.1 channels of advanced DSP and amplification, allowing for an unprecedented level of audio quality in your Bronco.

Harness the power of the DSP by using the USB connection to connect it to the mObridge DSP user interface for online firmware updates, full configuration and customization of the audio processing including channel mapping, parametric EQ, crossovers, channel filters, time-alignment, master/channel gain control, and many other features.

    Night and day improvement to the B&O nightmare in the Bronco. I have a ’23 Wildtrak and I can definitely tell the difference. I also installed a kicker 8″ into the stock enclosure and the amp has plenty of power for it. I have been extremely happy with the great customer service Mobridge has provided. I’ve had several questions since this is a new product, and they have been there to answer everything right away!

  2. Eric (verified owner)

    Anyone who has a stock B&O system in the Bronco knows the frustration that goes along with it. This amp/system is by far the best solution out there if you want to do it right and have the most control over tuning your system. Not only is the system easy to install with the plug-and-play configuration, but it sounds amazing and is designed to have enough power to drive whatever you can throw at it. Most importantly, the mObridge Support Team has been by far the best support team I’ve ever worked with. They stand by their products and are diligent in assisting with any issues or questions during install, system updates, etc.
