About the Dual AM505BT
A boatload of value
A boatload of value
Dual's AM505BT marine digital media receiver gives you outstanding sound, an extremely powerful built-in amp, and Bluetooth connectivity, plus a NOAA weather band tuner, a 3" color LCD screen, and Pandora control. With tons of cool features and marine-rated reliability, it's an outstanding value.
The attractive front panel hides a beast of a built-in amp that delivers 55 watts per channel.
Serious power, serious control
You won't need an outboard amp to drive your marine speakers. The AM505BT features a built-in Class D amp that delivers a whopping 55 watts RMS per channel, plenty of power to overcome wind and waves. You'll also appreciate the sound-shaping tools, which include a 3-band parametric EQ and 7 preset EQ curves, plus 2-level loudness control with adjustable frequencies. If you want to add more oomph to your system, you'll appreciate the preamp outputs.
Designed for marine use
There's no CD player in the AM505BT, so you can leave your discs at home and enjoy your much larger (and lighter!) digital music collection on the water. With built-in Bluetooth and an integrated microphone, you get the safety and convenience of hands-free calling and audio streaming with compatible smartphones and music players.
You'll enjoy plenty of options for entertainment and information with this receiver, highlighted by direct USB control for iPod and iPhone devices (and some Android phones). You can also listen to your favorite AM/FM stations, play music stored on a USB drive, or plug a portable player into the AUX input. You can mount the included USB extension cable in a convenient spot, making it easy to connect your device and crank some tunes.
Durable and practical
Dual made the AM505BT to survive the extremes of life on the water, with a UV-resistant exterior that resists fading, a detachable faceplate, and a conformal-coated PC board that resists corrosion.
All the openings are protected from salt and spray when not in use, and you can control all functions (except for Bluetooth) with the included remote. The 3" LCD display is easy to read day or night, and you can detach the face when you leave your boat at the dock and store it until you're ready to head out again. The 7-band NOAA tuner tells you what the weather's doing wherever you are.
Installation notes: This marine radio is water-resistant, but we recommend mounting it in a water-resistant enclosure or using a cover for best performance.
Bluetooth note: Use of this receiver's Bluetooth features will depend upon your phone's Bluetooth capabilities. Learn more in our article explaining Bluetooth profiles.
iPod/smartphone note: If you're going to use your iPod or smartphone with this receiver, be sure to check "Details" for compatibility information.

Marine Rated: The Dual AM505BT digital media receiver is specifically designed and built to last in harsh marine environments:
- UV Resistant Construction: The faceplate and other exposed elements of the receiver are carefully injection-molded using high-temperature ultraviolet resistant resins, preventing them from breaking down in the sun and giving you peace of mind to enjoy your music on the water even during the sunniest of days.
- PET Wrapped Chassis: This tough, direct, and moisture-resistant layer of PET (polyethylene) wraps the top and sides of the entire chassis - providing an additional measure of protection from the harsh marine elements.
- EDP Chassis: Applied using an electrical charge, EDP (Electrophoretically Deposited Paint) offers unparalleled protection against corrosion and rust resistance. All exterior metal surfaces including chassis, heatsink, and mounting sleeve undergo this process to ensure a long life in the marine environment.
- Conformal Coating: The conformal coated main circuit board has a transparent protective film applied to all surfaces. This additional layer of defense guards against dust, condensation, and corrosion - ensuring maximum longevity.
- Nanofics Coating: The front printed circuit board (PCB) includes an ultra-thin Nanofics coating to provide permanent high-level water and oil repellency. This protects against corrosion and short-circuiting cause by humidity and water splashes, without impacting device performance.
Detachable Face: The head unit's face-plate is detachable to deter theft and comes with a hard-plastic storage case.
3" Wide LCD: The head unit features 3" wide, single-line, 10-character LCD. This extra-wide, large, LCD allows you to easily view and navigate system menus, features, folders, and song information.
Text Scroll: You can change the scrolling style used for displayed information on the LCD screen. Choose from Off (no scrolling), Once (scrolls once), 15 Secs (scrolls once per 15 seconds), and On (constantly scrolls).
12/24 Hour Clock: The unit's built-in clock can be set to 12-hour or 24-hour mode.
Power-On Message + Demo: This feature allows a "Good Morning/Afternoon/Evening" text message to be shown on the unit's LCD screen when it is powered on. You can enable or disable the unit's demonstration mode.
Camera Input: The AM505BT features a composite video camera input and reverse wire for adding an optional backup camera (sold separately - see Accessories tab). The receiver's display will automatically switch over to the camera input when your vehicle is put into reverse gear (head units' reverse wire must be connected to vehicle's backup lamps).
Note: The camera input is meant as a visual aid only; never solely rely on a backup camera. In addition to using the camera, always physically look to make sure everything is clear around your vehicle.
IR Remote: The included 17-button IR remote control provides wireless operation of the digital media receiver. The remote is powered by a pre-installed CR2025 3V battery.
