Project Overview

Target Scenarios

Leisure boats, fishing vessels, yacht helm consoles, and other open-deck marine installations

Key Specifications

5.1-inch LCD with VA black film wide viewing angle; 10–16V DC with low-voltage warning (<10.5V)

Audio & Connectivity

Bluetooth 4.2 (music), USB playback & 1A charging, FM/AM (SI4745), AUX, EQ presets (POP / ROCK / CLAS / JAZZ)

Application Upgrade

Replacing fragile consumer head units with a purpose-built marine receiver that survives spray, sun, and vibration while delivering clear, powerful onboard sound

Pain Points of Traditional Marine Audio

On the water, generic car stereos and low-grade panels rarely survive salt air, humidity, and UV exposure for long:

Harsh Marine Environment

Spray, condensation, and salt spray corrode connectors and fog displays; without proper sealing and materials, electronics fail mid-season.

Weak Output at the Helm

Open cockpits and engine noise demand solid amplification. Underpowered units clip easily and cannot drive marine speakers cleanly.

Limited Sources On Board

Crews expect Bluetooth streaming from phones, USB libraries, and reliable AM/FM reception—legacy marine radios often lack modern codecs and flexible inputs.

Advantages of Our 5.1-Inch Marine MP5 Solution

Engineered for marine duty with industrial protection, strong amplification, and everyday connectivity.

Protection & Display: Built for the Deck

Designed specifically for marine environments—not a repurposed car unit with a sticker.

IP66 & Environmental Resilience

IP66-rated protection combined with salt-spray and UV-resistant construction helps the unit cope with splashes, sun, and coastal conditions.

5.1-Inch VA Wide-View LCD

Readable LCD with VA black film technology offers a stable image from typical helm viewing angles, day or night.

Power & Sound Quality: 25W × 4 with TDA7388

Enough clean power for typical marine speaker setups, with flexible tone shaping.

Amplifier & Formats

Output: 25W × 4 channels using TDA7388 amplifier IC.
Playback: Supports APE, FLAC, AAC, MP5, and WAV for high-quality files from USB.
EQ: POP, ROCK, CLASSICAL, and JAZZ presets to match music and ambient noise.

Connectivity: Bluetooth, USB, Radio & AUX

Wireless & Wired Sources

Bluetooth 4.2 enables wireless music streaming; USB supports playback plus 1A charging for phones; AUX accepts external players.

FM / AM Tuning

SI4745-based tuner covers FM 87–108 MHz and AM 530–1710 kHz for news, weather, and music when you leave the harbor.

Application Showcase

Compact Marine Front Panel 5.1-inch display and marine-ready controls suited for standard helm cutouts

Icon-Based Marine UI Quick access to Bluetooth, USB, radio, and core audio functions on open water

Partner Feedback

“We needed a head unit that could take spray at the console without dying after one season. This 5.1-inch marine MP5 has held up in salt air, Bluetooth pairing is straightforward for guests, and the 25W×4 output finally drives our cabin speakers without distortion. FM reception and USB playback cover everything from harbor news to playlists.”
