JBL's all new marine source unit, the JBL R4500, is the culmination of precise engineering and performance. With a bold new look and key audio features, this all weather stereo will be glad to accompany you and your family for a day on the water. An IPX7 weatherproof face patiently waits for rain, UV, salt and whatever else the elements may be. Understanding the need to listen to the ballgame, talk radio, or your favorite radio pop station, this source unit was thoughtfully engineered to master AM, FM and WB. If you’re looking to add additional speakers, such as 4 hardtop speakers to your existing 4 interior speakers, JBL’s 2 ohm stability will allow you to do just that.
