The PSU-300MTG is a sound system upgrade for 2015-2019 Ford Mustang base and gt models without the optional factory Premium 9-speaker sound system. This 300-watt upgrade boosts the overall sound performance of the factory sound system. The PSU-300MTG consists of an 8-inch powered subwoofer, Compact 4-Channel amplifier, and a remote bass knob. The system is compatible with 2015-2019 Ford Mustang base and gt models that do not have the optional factory Premium 9-speaker sound system. The PSU-300MTG does not use any valuable Trunk storage space. The subwoofer is just 3-inches Deep at its tallest point, so it and the amplifier fit under the glove compartment using the supplied bracket. Aside from maintaining storage space, 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 PSU-300MTG is designed for plug-and-play installation, which reduces labor time and gets you on the road quicker. The subwoofer and amplifier are pre-assembled onto the main mustang-specific bracket, so there’s no guessing where the products should be installed and no time spent connecting them to the bracket. A mustang-specific wiring harness is included, so no extra parts are needed. The bass knob mounts onto the dashboard so you can make bass level adjustments from the driver’s seat. The PSU-300MTG is compatible with the factory Ford base radio, an Alpine Universal head unit, or other aftermarket radio. The PSU-300MTG is authorized to be Sold By and Shipped From Amazon.
