Easy And Impactful Sound Enhancement

Use the included remote bass knob to conveniently control the bass level right from the dash. The PSU-300MTG is a 300-watt powered sound system upgrade for 2015-2019 Ford Mustang base and GT models that do not have the optional factory premium 9-speaker stereo system.

Hidden, Bolt-in Installation

All the components of the system are hidden away, saving valuable trunk storage space. The subwoofer is just 3-inches deep at its tallest point, so it and the amplifier are hidden and installed under the glove box. Aside from maintaining storage space and vehicle aesthetics, placing the subwoofer close to the front of the car allows for a proper sound stage in front of you, ensuring the best bass and imaging experience. The products are mounted in the car using the included bracket which is specifically designed to fit the Mustang.

Works With Any Radio

The PSU-300MTG is compatible with the factory Ford base radio, an Alpine universal head unit, or other aftermarket radio.
