D5 150W Plug N Play 4 Speaker System + Soundbar BoostBox™ (150.4)

Experience bigger, fuller, more immersive audio with the D5150.4, our 150-watt plug-and-play sound system designed specifically for the Evolution D5 (NOT compatible with the Plus model). This setup uses all four factory speaker holes—front and rear—to create a wider, fuller soundstage throughout the entire cart.

Powered by a Memphis MXA150.4 Marine Amplifier, four BA Signature 5¼” Marine Speakers, and our Soundbar BoostBox® head unit, the D5150.4 delivers cleaner signal, louder output, real stereo sound, and dramatically better clarity than the factory touchscreen could ever produce.

Zero wire cutting. Zero guesswork. Install in under an hour and finally enjoy the balanced, immersive audio the D5 should’ve had from the factory.
