Some manufacturers may just put automotive audio in a box marked "marine", but not JBL, they thoroughly develop their components for the harsh marine environment. Circuit boards are fully encapsulated in a newly developed PUC moisture coating to dramatically improve reliability. The coating is visible under black light, and every component is visually inspected to insure that the circuit boards are fully covered.
