Doubtful. The design of the bed audio uses the entire composite panel vibrating to produce sound waves. While this doesn’t produce very high quality, or well directed sound, it succeeds in moving a lot of air.
I saw an interview with an engineer from Honda America who filled the bed 3/4s full of mulch and tested the audio. It wasn’t loud, but you could still hear it.
