Most Boats Lose Bass Completely Once You Get Moving
At the dock, many marine systems sound decent.
But once you’re cruising, bass disappears because of:
- wind noise
- engine vibration
- open-air sound loss
- hull resonance
That’s why most factory boat systems sound weak and flat at speed.
The Rockford Fosgate M1D4-12 is built to deliver deep, accurate bass that stays strong in real boating conditions.
