However, if you have a disability we are here to help you. Please call our disability services phone line at (262) 242-5599 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for anyone with a disability.

MediaMaster® 105 - Premium, weatherproof marine source unit with full-color LCD display

Enjoy great audio wherever your adventures might take you, with the MediaMaster® 105, a Premium Source Unit designed to withstand anything Mother Nature can dish out. This full-featured source unit delivers top-flight sound performance and advanced audio features specifically designed for marine and powersports applications. Its rugged, weatherproof (IP67 rated) chassis houses an ultra-bright, 3.5-inch full-color LCD display, with separate Day/Night lighting themes for outstanding visibility, even in bright sunshine. When in motion, you will also appreciate the clean user interface with big text and large backlit controls.
Because sound quality is our top priority, the MM105 is not equipped with an internal amplifier designed to drive loudspeakers directly. Instead, it offers twelve channels of audiophile-quality, preamp level outputs to deliver crystal-clear signals to high-quality marine amplifiers. These are deployed via four configurable, nameable audio zones, each with its own set of independent control options, making the MM105 adaptable to a wide range of system types. On-the-fly, level controls make adjusting each or all audio zones a breeze, while a useful volume limit feature ensures that nobody gets blasted inadvertently. All zones feature our Zero-Clipping audio circuit design, with self-limiting tone controls to keep the audio clean at high listening levels, reducing the likelihood of speaker damage.

With certified NMEA-2000® connectivity, the MM105 is also an ideal partner to your Garmin , Lowrance , Raymarine or Simrad Multifunction Display! (MFD)

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
