Wiring & Accessories

High-tech or traditional, we have boat network accessories and marine power accessories to accompany your new system.

We Know Staying Connected is Important!

From weather conditions to radio contact with other vessels, staying connected is paramount to safety on the water. A trustworthy connection can be more than a matter of making sure the XM Radio will belt out a rocking playlist while you're making that catch - communications with other vessels and updated weather information are essential to your safety. Be confident in your setup - from pleasure to essentials - with updated wiring and accessories from Defender.
