True Marine Audio: While some manufacturers simply put automotive equipment in a box marked "marine", Prospec's JBL components are thoroughly developed for the marine environment. Circuit boards are encapsulated in a newly developed PUC moisture coating which dramatically improves reliability. Unlike the coating used by most companies in the marine industry, PUC coating is visible under a black light. This makes it possible to visually inspect every unit to make sure that the circuit board has been fully covered!

All of the new JBL stereos now also offer Electronic Shock Protection! ESP is a brand new innovation for the marine industry. It basically works like a computer hard drive: it temporarily spins a CD at a faster rate than normal, giving it the ability to copy and store the music ahead of time. That storage acts as a buffer, so when the boat encounters a large jolt, the skipping is virtually eliminated!

JBLs' exclusive 5-Year Owner Protection Plan is proof positive of our confidence in the quality of our products. We invite you to check out our new generation of stereos, speakers and other great additions for your marine audio system. With upgraded circuitry, an improved CD mechanism and a bolder LCD positive readout for better viewing, these products are the latest advancements in marine entertainment. All JBL radios (excluding the MR-4 and MR-29) are also equipped with an auxiliary input for adding MP3, satellite radio or DVD to your system.
