Get your system started

If you want to upgrade your boat's marine audio system, this receiver/speaker package is a great starting point. The Clarion M505 marine digital media receiver gives you plenty of functionality, while the 6-1/2" marine speakers will make music sound great from any source. Clarion has earned its reputation for building marine electronics tough enough to withstand salt water, heavy fog, blistering sunlight, and lashing rain, so this system will sound great for years.

Built-in Bluetooth® for your boat

The M505 receiver lets you stream music from your smartphone or any Bluetooth device to your boat's sound system. Bluetooth aptX processing (also found in many Android smartphones) restores the sparkle that's lost during compression, so you'll hear vastly improved sound quality.

iPod® and iPhone® controls

The M505 gives 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 listen to your favorite stations when your iPhone's connected via USB. Song and artist information shows up clearly on the sharp-looking black-on-white 2-line display.

If you've ripped your entire CD collection and gone digital, you can plug a thumb drive into the front USB port and enjoy all your favorite MP3 or WMA tunes, or you can play your digital music player through the handy front AUX input. You can also enjoy the vast array of programming on satelllite radio by connecting a SiriusXM tuner (sold separately, subscription required).

Sculpt the sound you want

Clarion built this rugged marine receiver to last, but it's also designed to deliver outstanding sound. The 3-band equalizer lets you adjust the highs, mids, and lows to suit your preferences, and you can use the built-in frequency filters and subwoofer controls to get the best possible performance from your system. You'll find the three sets of preamps handy if you're adding amplifiers to your sound system.

Dual zone control lets you split the boat into two distinct areas to suit your needs. Using a special controller (sold separately), you can crank up the bow speakers for max performance, while leaving the cabin speakers at a more conversational level.

Sweet speakers, too

These 6-1/2" Clarion marine speakers will bring serious audio performance to your boat, too. These full-range speakers will handle up to 50 watts RMS (100 watts peak) and they're tough enough to handle high volume all day long. A rugged die-cast aluminum basket protects the entire structure, and the high-impact plastic grilles are UV-treated to resist punishing sunlight. A liquid drainage system designed into the structure keeps rain and spray from pooling up. All Clarion marine speakers are designed to meet or exceed industry standards for UV-ray, salt, fog, and moisture resistance. These speakers require an opening of 5.678", so we recommend measuring your boat's speaker openings before ordering.

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.

This marine digital media receiver will not play CDs.

Marine, Display, & Remote Features

Marine Tested: The Clarion M505 Marine digital media receiver has been engineered and tested for use in the harsh marine environment. The M505 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.

High Visibility LCD: The two-line, 13-digit, high visibility LCD (with white background and black characters) on the M505 allows numbers and characters to be displayed clearly in almost any lighting condition.

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).

IR Remote: The Clarion M505 comes supplied with an IR remote control for wireless operation of the digital media receiver. The remote provides music playback & search controls. The remote operates off of a single CR2025 Lithium cell 3-volt battery.

Optional Wired & Wireless Remotes: The unit is equipped with a rear mounted 8-pin DIN connector to accommodate optional Clarion wired & wireless remote controls.

  • Wired Remote: The MW1 (020MW1; sold separately) is a hardwired remote control with an LCD display.
  • RF Remote: The Clarion MF1 (020MF1, sold separately) is a RF remote control which is waterproof and designed to float. The MF1 meets or exceeds ASTM B117 (Salt/Fog Exposure), ASTM D4329 (UV Exposure), and IP67 (International Protection Rating).
  • WiFi Remote Module: The Clarion MF2 marine remote module (020MF2, sold separately) features built-in WiFi and allows you to control your 2009-up Clarion marine receiver via the free Clarion MF2 app on your Apple iPod/iPhone/iPad (iOS 6.0+).

Note: When two remotes are used in combination with one another, Clarion's Y-adapter (020MWRYC, sold separately) is required.

Steering Wheel Remote Compatibility: The head unit features an OEM steering wheel remote control input on the rear of the unit that lets you keep your vehicle's factory radio steering wheel remote controls when used with an optional steering wheel audio control adapter (sold separately).

Optional NMEA 2000 Interface Module: Clarion's MW6 NMEA 2000 Compliant interface module (020MW6, sold separately) allows Clarion marine source unit to be seamlessly added to your boat's onboard NMEA 2000 network, enabling control of the Clarion source unit directly from the boat's Multi-Function Display (MFD) device.

Bluetooth & iPhone Integration

Wireless Audio Streaming: The Clarion M505 supports wireless audio playback (AD2P) and control (AVRCP) of a Bluetooth-enabled smartphone or audio player, plus song/artist information display and support for aptX music streaming. You are able to wirelessly stream your stored music library, music apps, and other content on your Bluetooth source device to the Clarion marine receiver.

  • SBC + aptX Codecs: In addition to support for the standard SBC Bluetooth audio codec, the M505 incorporates the Qualcomm's lossless Bluetooth aptX codec (primarily for Android OS 4.0+ devices) which helps retain sound elements lost during digital compression of audio files, ensuring users the ability to always enjoy high quality sound with wireless convenience.
  • Control & Display: The receiver provides basic playback control (Play/Pause, FF/RW, Skip, Random/Repeat) of your streaming Bluetooth audio through its front-panel. Advanced music browsing and navigation will still need to be done from your Bluetooth source device. The head unit will display your stored music and music app's song information; such as Artist name and Song/Album title (not compatible with all apps).
  • Simple Secure Pairing (SSP): With Secure Simple Pairing (SSP), you can easily pair a Bluetooth device to the Clarion M505 without having to enter pin codes or go through complicated settings. When a paired Bluetooth device is in close proximity to the receiver, the auto connection function automatically pairs the two units. You can pair up to three Bluetooth-enabled devices to the Clarion head unit, but only one can be used at a time.
Note: When an incoming call or outgoing call is in progress from your Bluetooth enabled phone, audio streaming will be paused so you can take your call. Once the call is finished, your streaming music will resume.

iPod/iPhone Direct Connection: The Clarion M505's front-panel USB port lets you connect select Apple iPods and iPhones for music playback. Simply use the cable that came with your iPod/iPhone device or an Apple certified cable (sold separately). The M505 supports audio playback, control, display, and charging of your compatible Apple device.

  • Control: The Clarion head unit allows you to navigate your Apple device's music by Playlist, Artists, Album, Genre, Composer, Song, Audiobooks, or Podcast. These categories and music files inside these categories will be listed alphabetically. The head unit also controls Play/Pause, Previous/Next Track, Fast-Forward/Rewind, and Random/Repeat functions. You can also choose to use the touchscreen of your connected Apple device to access additional music apps and other playback options.
  • Display: The head unit will display artist name, song title, and album title from your Apple devices stored music library and select music apps (not compatible with all apps).
  • Charging: The head unit's USB connection provides 1A of current to power and charge your connected iPod/iPhone when your vehicle's ignition switch is set to the 'ACC' or 'On' position (if your iPod/iPhone has no initial battery charge, then the unit will not recognize it).

Audio & Speaker Section

MOSFET Amplifier: The Clarion M505 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 M505 are as follows:

  • CTA-2006 Specs: 20 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)
  • Maximum Power Output: 50 watts x 4 channels (200 watts total)
Note: The power specifications for the M505 are compliant with the CTA-2006 Mobile Amplifier Power Testing and Measurement standards from the Consumer Technology Association (CTA). These standards were developed as a way to equitably compare power specs from model to model and between manufacturers.

4V/6Ch RCA Outputs: With 6-Channel 4-Volt RCA Outputs, you are free to add external power amplifiers to create a more powerful, sophisticated audio system. What's more, the 4-volt output assures a pure, high quality signal for your entire sound system. The non-fading subwoofer preamp output features an independent level control (+/-6) and phase adjustment (normal/reverse).

Low-Pass Subwoofer Filter: The Low-Pass Filter (LPF) for the subwoofer preamp output (when activated) 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 80Hz, 120Hz, 160Hz, or Through (full-range).

3-Band EQ + Presets: The Clarion M505 incorporates a 3-band EQ and 11 EQ presets. The EQ presets consist of Flat, Jazz, Pop, Classic, Rock, News, Urban, Rave, Movie, Techno, and User. The User preset allows you to adjust the head unit's 3-band EQ (Bass, Mid, & Treble) from -7 to +7. EQ settings are applied to all sources.

Loudness: The Loudness features enhances both the bass & treble frequencies at lower volumes.

Dual Zone Audio with Fixed Output: The Clarion M505 is fitted with a stereo line-level output (fixed) for Dual Zone audio; requires an external amplifier in Zone 2. With this function, it is possible to split your boat into two discrete zones to enjoy different volume levels of entertainment. For instance, the bow can be tuned-in to a higher volume level for enjoyment in the wind while the stern can enjoy the music at a lower volume to accommodate conversations. Volume levels from the fixed zone are controlled by optional external volume control device or "pot" (sold separately). This is ideal for separate areas such as salons, wakeboard towers, and open bows

Marine Speakers: The Clarion CMG1622R speakers are designed and treated for use in the harsh marine environment. The speakers meet or exceed the ASTM B117 Salt/Fog Exposure standard, as well as the ASTM D4329 UV Exposure standard. Each speaker features a mica-injected polypropylene cone woofer with a Santoprene rubber surround and a titanium dome tweeter. The basket and grille are made of durable UV resistant plastic. The magnet is fully enclosed to protect it from corrosion. The speaker includes stainless steel mounting screws and an integrated rubber mounting gasket for a watertight fit. The speaker frame and grille have an integrated liquid drain channel to allow water to escape from the front of the cone area. The CMG1622R speakers also feature corrosion-resistant gold-plated terminals.
