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.

Marine, Display, & Remote Features

Marine Certified: The Dual AM425BT marine receiver is specifically designed and built to last in harsh marine environments.

  • Conformal Coating: A transparent protective film is applied to surfaces of all interior printed circuit boards. This additional layer of defense guards against dust, condensation, and corrosion; ensuring maximum longevity in demanding marine installations.
  • UV Resistant Construction: The faceplate and other exposed elements of the receiver are carefully injection-molded using high-temperature ultra-violet resistant resins, preventing them from breaking down in the sun and give you peace of mind to enjoy your music on the water.
  • EDP Chassis: Applied using an electrical charge, EDP (Electrophoretically Deposited Paint) offers unparalleled protections against corrosion and rust resistance. All exterior metal surface including cassis, heatsink, and mounting sleeve undergo this process to ensure a long life in the marine environment.
  • PET Wrapped Chassis: This tough, dirt and moisture-resistant layer of PET (polyethylene) wraps the top and the sides of the entire chassis; providing additional measure of protection from the harsh marine elements.
  • Silicone Cover: Injected from high-grade silicone, this removable cover guards the receiver's front-panel USB/3.5mm input, protecting if from water splashes and debris. A convenient tether provide and attachment to the receiver, ensuring the cover is removable but won't get lost.
Note: Even though the conformal coating and other marine features makes the receiver water-resistant, it can be further protected by an optional universal marine cover; such as the Metra (120999005B, sold separately) or Scosche (142ACM1, sold separately).

Front-Panel Display: The Dual AM425BT marine CD receiver features a detachable front-panel display with motion control.

  • Positive-Type Display: The vibrant positive-type, LCD provides enhanced visibility under the toughest boating environments. High-contrast black characters on a white background ensure readability in any situation; from total darkness to direct sunlight. The display brightness can be set to High, Medium, or Low.
  • Motion Control: You can use simple hand gestures to control the receiver's most commonly used functions such as play/pause, volume up/down, and track forward/backwards (functionality will depend on connected device).
  • Clock Display: The marine head unit features a 12/24-hour clock; the clock will display in 12-hours in US tuning mode and 24-hours in European tuning mode. The clock can be set to remain on even when the head unit is powered off.
  • Detachable Face: The head unit's face-plate is detachable to deter theft (no face case provided). An optional soft face case (142DFC1X, sold separately) can also be purchased for this unit.

IR Remote: The Dual AM425BT comes supplied with an 17-button IR wireless remote control which provides complete control of the CD receiver.

Built-in Bluetooth

You can also select a phone number from a recent call list (dialed/missed/received) or quickly redial the last number. Use the included external microphone to speak into during your phone conversation, while the other party will be heard through your vehicle's speakers. Your car audio speakers will mute automatically during a call.

Audio & Speaker Section

MOSFET Amplifier: The Dual marine receiver is equipped with a MOSFET amplifier. Compared to conventional power supplies, the MOSFET amplification circuit is smaller and more efficient, and it delivers increased power with less distortion and absolutely zero on/off switching noise. More power means louder and cleaner music at higher volumes because you're not pushing the limits of the amplification circuit. The power output specs for the head unit are as follows:

  • CEA2006 Specs: 18 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)
  • Maximum Power Output: 60 watts x 4 channels (240 watts total)
Note: The power specifications for this head unit are compliant with the CEA2006 Mobile Amplifier Power Testing and Measurement standards from the Consumer Electronics Association (CEA). These standards were developed as a way to equitably compare power specs from model to model and between manufacturers.

2V/2Ch Pre-outs: The Dual AM425BT is outfitted with 2-volt/2-channel pre-outs for connecting an external amplifier. These stereo pre-outs fade with the rear speaker channels. The unit does not offer a low-pass crossover or sub control.

Equalizer: The Dual CD receiver features the following preset EQ curves (Flat, Pop, Jazz, Classic, Beat, Rock, or User) to customize your music listening. The User mode allows you to manually adjust the receiver's Bass & Treble settings.

Loudness: The Loudness function enhances the bass & treble frequencies at low volumes. This feature can be turned on or off.

Source Volume Level: The Source Volume Level control allows a gain adjustment for each audio source (Tuner, Aux, USB, iPod). You can set the source volume level (+/-3dB) for each mode, depending on the relative volume of each audio source.

Programmable Turn-On Volume: You can set the AM425BT to power-on to the same volume level (0-30) every time.

Marine Speakers: Included in this marine package is a pair of marine-rated speakers (item # DMP672). The speakers feature a two-way dual cone design with a 6.5" injection-molded polypropylene cone woofer with poly-coated surround and a 1" cone tweeter. The speakers offer a frequency response of 45-15kHz and can handle up to 20 watts (RMS) or 100 watts (peak).. The speakers are rated at 4-ohm with a sensitivity rating of 88dB (1W/1M). The marine speakers feature a white plastic frame and include white plastic grilles that are detachable. Dimensions are as follows -

  • Mounting Height: 1.0625"
  • Mounting Depth: 2.125"
  • Frame Diameter: 7.125"
  • Cut Out Diameter: 5.125"
  • Bolt Pattern: 4 screw holes that are 4.5" apart
