Why should I put a marine receiver on my boat?

Few things are better than relaxing to your favorite music out on the water. Sure, you can put a car stereo in your boat, but a marine receiver is designed to stand up to the damage that humidity, moisture, and salt can cause, so it'll have a much longer life span in your vessel. And today's marine receiver offers all the features you want when you're cruising, including iPod controls, satellite radio capability, and connections for the outboard amps in your system.

Our take on the Clarion M303

Master your music

Clarion's M303 marine CD receiver offers built-in iPod® and iPhone® controls that give you mastery over your music collection, including genre/album/song title search using your iPod control wheel. If you're a Pandora® Internet radio fan, you can even listen to your favorite stations when your iPhone's connected via USB. Song and artist information is clearly displayed on the sharp-looking black-on-white display. Of course, you can also play your favorite CDs, including music you're ripped to disc in MP3 or WMA formats.

Built-in Bluetooth® from Parrot

This isn't just Bluetooth, it's Parrot Bluetooth. Parrot, an industry leader in Bluetooth electronics, brings you the convenience of hands-free calling, plus wireless music streaming from your Android Smartphone. The M303 uses a built-in microphone to pick up your end of the conversation, and you have the option of adding an external mic for even better call clarity.

Sculpt the sound you want

The M303 is built for long-lasting durability, but it's also designed to give you outstanding sound. The 3-band parametric equalizer lets you adjust the highs, mids, and lows to suit your preferences, while the bass boost circuit is always ready to add a little extra boom to your boating. You can use the built-in frequency filters and sub controls to get the best possible performance from your system.

Terrestrial and satellite radio-ready

Clarion's excellent AM/FM tuner hauls in plenty of stations when you're within range. And this receiver works with the latest SiriusXM tuner (not included), so you can enjoy satellite radio's amazing variety of entertainment, news, and sports channels when you're miles and miles offshore.

Remote (control) possibilities

You can add on Clarion's MW1 or MW4 wired remote controls. Just place one near the helm and control the receiver installed below. Or pick up Clarion's MF1 remote and enjoy the freedom of wireless control.

Marine-rated durability

If you're looking for a versatile, multi-source receiver that's tough enough to handle the extremes of a marine environment, the M303 has a lot to offer. Clarion invests thousands of hours into making their marine electronics tough enough to withstand salt water, heavy fog, blistering sunlight, and lashing rain.

Note: Bluetooth compatibility with this receiver may vary, depending on your phone and service provider.

      Marine Rated

      Marine Tested: The Clarion M303 Marine CD receiver has been engineered and tested for use in the harsh marine environment. The M303 meets ASTM B117 and ASTM D4329 guidelines ensuring the receiver's resistant to salt, fog and UV exposure. The receiver features a drip shield chassis to keep water from dripping onto the unit's internal circuits. In addition, the head unit's PCB and microprocessor are conformal coated to protect them from corrosion.

      Water Resistant Covers (optional): Even though the conformal coating makes the receiver water-resistant, it is still recommended that it be used with a universal marine cover such as the Metra (120999005B, sold separately) or Scosche (142ACM1, sold separately).

      Built-in Bluetooth

      Bluetooth Technology (powered by Parrot): The Clarion M303 is equipped with built-in Bluetooth ver. 2.0+EDR (powered by Parrot), allowing you to make and receive phone calls wirelessly through the receiver; as well as stream music wirelessly from your smartphone to the head unit. In order to use Bluetooth wireless technology, your phone must also be Bluetooth compatible and be able to interpret certain profiles. This unit is compatible with the following Bluetooth Profiles:

      • Hands-Free Communication: HFP (Hands Free Profile), PBAB (Phone Book Access Profile).
      • Audio Streaming: A2DP (Advanced Audio Distribution Profile), AVRCP (Audio/Video Remote Control Profile).
      Note: The Clarion M303 may not be compatible with all Bluetooth enabled phones or audio players. Visit Clarion Bluetooth Support for complete list of compatible phones and players.

      Pairing: Before using your Bluetooth enabled device, it must be paired to the M303. You can register up to five Bluetooth enabled cell-phones with the Clarion marine head unit (only one paired phone can be used at a time). The Clarion M303 can be paired with most Bluetooth enabled mobile phones, including the Apple iPhone and most Android Smartphones.

      Hands-Free Communication (w/ Integrated Microphone): The M303 supports Bluetooth hands-free communication from your Bluetooth enabled mobile phone.  The M303 can be set to automatically answer your incoming calls and mute any music audio to your vehicle's speakers so you can instantly carry on a phone conversation hands-free. An integrated front-panel microphone carries on your side of the conversation while your car's speakers are used to hear the other person. You can make a call by entering the phone number, selecting a contact from your Phonebook list, or using the Call History Log of received/dialed/missed calls.

      • Answering A Call: During an incoming call, the caller's phone number will be seen on the unit's LCD and a ring-tone will be heard through your car stereo speakers. You can then manually answer the incoming call from the head unit's front-panel controls. You can also set the unit to automatically answer an incoming call within 5 seconds.
      • Making A Call: You can make a call using the Clarion marine head unit's front-panel controls.
        • Direct Dial: Outgoing calls can be made be entering telephone numbers (0-9, *, #, +) directly via the car stereo's rotary control knob.
        • Phonebook: You can search for contact names in your mobile phone's phonebook from the Clarion M303 and then make your call. The head unit can store up to 500 contact numbers.
        • Call Log: You can also make a call by searching your mobile phone's call history (Received/Dialed/Missed) from the Clarion M303.
        • Redial: You can simply redial the last number dialed with a press of a single button on the marine head unit.

      Optional External Microphone: The Clarion RCB-199 (020RCB199, sold separately) is an external microphone which can be connected to Clarion M303. The RCB-199 external microphone provides better performance in noisy environments than the integrated microphone found on the front-panel of the head unit. The microphone features an attached 13.25' cord terminated by a right-angle male 3.5mm connector which plugs into the microphone input on the rear-chassis of your compatible Clarion head unit. The microphone also features an integrated sun-visor clip for mounting the external microphone in your vehicle. The integrated bracket allows the microphone to swivel left-to-right and rotate up-or-down.

      Wireless Audio Streaming (w/ metadata): The Clarion M303 also supports wireless audio playback (AD2P) and control (AVRCP) of a Bluetooth enabled audio player or smartphone. The M303 will be able to control your stored music's basic playback functions; such as Play/Pause, Previous/Next Track, and Fast-Forward/Reverse. The M303 also supports audio streaming of music apps from your smartphone with basic control and metadata display. When an incoming call or outgoing call is in progress from your Bluetooth enabled mobile phone, audio streaming will be paused so you can take your call. Once the call is finished, your streaming music will resume.

      Note: Apple iPod/iPhone software updates may change functionality results. If you download a newer software version, you may need to reset the head unit and your iPod/iPhone to regain functionality. If this doesn't work, you may need to wait until a newer software update is available.

      Auxiliary Input: The M303 features a rear-panel stereo Auxiliary input, so you connect your external portable audio player or portable satellite radio receiver to this head unit. You can set the Auxiliary input sensitivity level to Low, Mid, or High to match the volume output of your connected external audio device.

      Audio Section

      MOSFET Amplifier: The Clarion M303 employs a MOSFET (Metal Oxide Semiconductor Field Effect Transistor) power amplifier capable of delivering 45W (Peak) x 4ch of high quality sound with superior linearity & less distortion than conventional power amps, even with the volume cranked up.

      CEA2006 Compliant: The power specifications for the M303 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. The power output specs for the M303 are as follows:

      • CEA2006 Specs: 19 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)
      • Maximum Power Output: 45 watts x 4 channels (180 watts total)

      BeatEQ: BeatEQ lets you tune the sound to your liking, depending on the category of music, for a more fulfilling listening experience. The Clarion CD receiver provides 4 preset EQ curves (Bass Boost, Impact, Excite, Off) and 1 custom EQ curve. Bass Boost emphasizes the bass portion of your music; Impact emphasizes the bass & treble portions of your music; Excite emphasizes bass, midrange & treble portions of your music; while Flat sets the bass, midrange, & treble to 0. The Custom EQ lets you freely customize the frequency, Q-factor, and level of the bass, midrange, &  treble.

      BeatEQ (Custom Mode) Frequency Q-Factor Level
      Bass 50Hz, 100Hz, 200Hz 0.7, 1, 1.4, 2.0 -7 to + 7 dB
      Midrange 500Hz, 1kHz, 2kHz
      Treble 5kHz, 10kHz, 15kHz
      Note: BeatEQ settings are applied to all sources.

      Magna Bass EX (Extend): The Magna Bass Extend feature does not adjust the low frequencies like the normal sound adjustment function, but emphasizes the deep bass frequencies to provide you with a dynamic sound. This circuit boosts bass at an ultra-low frequency of about 50Hz, creating a rich, deep, defined bass rather than the muddy, booming bass of a standard loudness control. What is more, boost levels are dependent on the system volume, resulting in balanced system response and dynamic bass reproduction.

      4ch/2V Preamp Output: The Clarion M303 features 4ch/2V RCA line level outputs (Front/Rear). The unit's rear preamp outputs can be configured as a dedicated non-fading RCA subwoofer output with a low-pass filter and level control (+/-6).

      Built-in Crossovers: The Clarion M303 is equipped with built-in low-pass and high-pass crossovers.

      • Low-Pass Subwoofer Filter: The Low-Pass Filter (LPF) for the subwoofer preamp output will send only the low frequency range through the preamp outputs to ensure superb performance with a connected subwoofer. The low-pass filter can be set to 60Hz, 90Hz, 120Hz, or Through (full-range).
      • High-Pass Filter: The M303 features a High-Pass Filter (HPF) for the unit's front & rear channels, via speaker-output or preamp-output. You can adjust the high-pass filter from 60Hz, 90Hz, 120Hz, or Through (full-range). The HPF prevents low bass notes from distorting your front & rear speakers. The high-pass filter setting effects both the front & rear channels of the head unit.

      Beep: The marine head unit provides an audible beep to confirm button operation. This function can be turned On or Off.

      Display Features

      Ergonomic Face Design: The Clarion M303 features an easy-to-use rotary volume control and easy-to-read illuminated buttons on the face which are laid out in an asymmetrical design to place the most used features within a specific area for ease of use and less user distraction.

      Digital LCD: The single-line digital LCD, with white background and black characters, on the M303 allows numbers and characters to be displayed clearly in all lighting conditions.

      Illumination Dimmer: The receiver's display automatically dims to a preset brightness when the vehicle's headlights are turned on. The wiring harness includes an orange/white lead that should be connected to the vehicle's parking light circuit in order for the dimmer feature to operate.

      Screen Saver: This unit is provided with a Screen Saver function which allows you to show various kinds of patterns and characters in the operation status indication area of the display in a random order. You can turn this function on or off. If the button operation is performed with the screen saver function on, the operation display corresponding to the button operation is shown for about 30 seconds and the display returns to the screen saver display.

      Detachable Face Security: This unit features Detachable Face Security. A face-case is included to protect the unit's faceplate when detached. A face-fixing screw is supplied for making the face non-detachable, if desired. An optional soft face case (142DFC1X, sold separately) can also be purchased for this unit

      Remote Control

      Optional Remote Control: The unit is equipped with a rear mounted DIN connector to accommodate an optional Clarion wired marine remote control (020MW1/020MW4; sold separately). You can also choose to add on the Clarion MF marine RF remote control (020MF1, sold separately). When the wired remote and RF remote are used in combination with one another, a Y-adapter is required (020MWRYC, sold separately).

      Great all around deck

      Crutchfield Customer Review (What's this?)
       
      Very satisfied with this stereo. Using it in my boat paired with a MW1 remote. I have it paired with my iPhone 4S. Nice having the ability to plug in via USB and have full control of the iPod as well as pandora control. Or switch over to Bluetooth audio streaming and I can still switch to next song on iPod or pandora. In Bluetooth streaming as well as usb, the radio and mw1 show all the track info which is nice to see. When a call comes in the called id is shown on both the radio and Mw1 remote as well.
      Pros:
      USB music connection as well as Bluetooth streaming.
      Cons:
      Only 2 sets of pre amp RCA outputs. Clarion should know that many boat owners try to fit as much sound as possible while out on the water. What better way then with amplifiers for all speakers.
