About the Dual AMCP425BT
A nice upgrade to your boat's audio system
A nice upgrade to your boat's audio system
A good sound system makes a day on the water even better. With this AMCP425BT marine audio package from Dual, you can upgrade your system without emptying your wallet. This combo includes a marine-rated AM425BT CD receiver, a set of rugged DMP672 6-1/2" marine speakers, and mounting hardware. It's a quality starter system that gives you great sound, rugged reliability, and smart features you'd expect to find in gear costing a whole lot more.
Marine-rated quality, plus motion control
Dual's AM425BT CD receiver gives you plenty of playback options and nifty high-tech features. 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. You can also listen to your favorite AM/FM stations, play music stored on a USB drive, or plug an portable player into the minijack aux input.
The AM425BT offers bass and treble controls, along with three preset modes. You'll find a set of 2-volt RCA outputs, handy if you want to connect an external amp or marine powered sub.
And the incredibly cool thing is that this receiver gives you motion control over basic functions like play/pause, volume, track selection, and (in select cases) your iPhone. Just wave your hand to move to the next track or turn the volume down — that's a very handy thing to have when you're out on the water.
Built tough to withstand the elements
Dual made the AM425BT 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. It blends into most boat interiors and offers an impressive list of features. 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 detachable faceplate features a 10-character display that's easy to read day or night. When you leave your boat at the dock, you can detach the face and store it until you're ready to head out again.
All this, and speakers, too
The included Dual DMP672 marine speakers pair up perfectly with this receiver. These durable 6-1/2" dual-cone speakers provide plenty of punch and excellent clarity. With injection-molded polypropylene cones and poly-cloth surrounds, these rugged speakers will resist sun and spray to give you great sound for seasons to come.
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.
iPod/smartphone note: If you're going to use your iPod or smartphone with this receiver, be sure to check "Details" for compatibility information.
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.
