Want to boost the bass and volume in your Accord, but don’t want to deal with the hassle of a custom install and big price tag? The plug-and-play PSU-300ACD Powered System Upgrade is the answer for you.


  • 300-watt plug-and-play powered system upgrade for the 2018-Up Honda Accord 4-Door*
  • 45W x 4 + 120W RMS System Power (300W)
  • 8-inch powered subwoofer
  • 4-channel compact amplifier
  • Remote bass knob
  • Accord-specific brackets and wiring harnesses included

* Not compatible with the factory premium amplified system or with EX-L and Touring models


Enjoy a significant increase in sound performance for your Honda Accord with the PSU-300ACD. This 300-watt system consists of an 8-inch powered subwoofer and 4-channel compact amplifier. Use the included remote bass knob to conveniently control the bass level right from the dash. The PSU-300ACD is a 300-watt powered sound system upgrade for 2018-Up Honda Accord 4-door models (LX, Hybrid, Sport, EX) that do not have the optional factory premium amplified sound system and are not Touring models.


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 front passenger’s seat. 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 Accord.


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