Marine Rated CD Receiver & Speaker Package

Marine Receiver: The Sony CDX-M20 Marine AM/FM CD receiver features a UV resistant faceplate (tested under ASTM G154), a conformal coated circuit board for marine use and a plastic cover over the top of the chassis to protect against humidity.

• UV Resistance: UV Resistant front-panel coating protects faceplate to help prevent discoloration from the sun. Meets the standard for ASTM G154 for UV resistance.
• Conformal Coated Circuit Boards: Conformal coated circuit boards protect the electronic assembly from damage due to contamination, salt spray, moisture, fungus, dust, and corrosion caused by harsh or extreme environments.

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).

Memory Backup: The head unit's last settings are stored automatically in the unit's non-volatized internal memory. Settings include Sound adjustments (except volume), Setup items (except clock), and Tuner presets.

UV & Water Resistant Speakers: These marine speakers feature UV and water resistant removable white grilles, speaker baskets, polypropylene cones, rubber woofer surrounds, and poly cone tweeters. Marine Certifications include:

• Water Resistant: IPx5
• UV Resistant: ASTM G154
• Salt Resistant: ASTM B117
