Detailed FAQ Section

1. Is Marine Audio MA112 Stereo waterproof?

While the Marine Audio MA112 Stereo is not fully submersible, it is designed to be water-resistant. The faceplate and housing are sealed to protect against splashes, humidity, and sea spray. It is suitable for use in open boats as long as it is not directly exposed to heavy rainfall or submersion. For best results, install the stereo in a protected console area or use a splash guard cover.

2. How do I connect my phone via Bluetooth to Marine Audio MA112 Stereo?

To connect your phone, first power on the stereo and enable Bluetooth mode. On your smartphone, go to Bluetooth settings and search for available devices. The stereo will appear as “MA112” or a similar name. Select it, and pairing will be confirmed. Once connected, you can stream audio directly from your favorite apps like Spotify, Apple Music, or YouTube without using wires.

3. What speakers work best with Marine Audio MA112 Stereo?

The stereo supports a total output of 160 watts, split across four 40-watt channels. It pairs well with marine speakers rated between 40–60 watts RMS per channel.
