M3 Marine Tower Speakers - Big Speaker Sound and Stunning Looks
• Oversized 7.7-inch coaxials deliver stronger output and better power handling than smaller speakers.
High-Performance Coaxial Drivers
High-Performance M3-Series 7.7-inch coaxial speakers for moderate power, standard output applications.
Top-Quality, Salt-Water-Grade Materials
• Pipe mounting fixtures (fixed and swivel) are available for the most popular pipe diameters.
• Deck/Surface mount fixture with ratchet-adjustable pitch is also available.
• The speaker and rear decorative JL Audio logo cap can be adjusted to compensate for different mounting roll angles.
Choose Your Look
• Available in two grille styles: “Classic” or “Sport”, both in Gloss White. Sport models are also available in a sleek, all Gunmetal finish.
• Allows you to match the look of the speakers to the theme of the boat interior.

1x JL Audio MV400/4i 4-channel Class D Full-Range Amplifier with integrated DSP, 100 W x 4 @ 2 ohm/75W x 4 @ 4 ohm - 14.4V - (MV400/4i)
JL Audio MV400/4i 4-channel Class D Full-Range Amplifier with integrated DSP, 100 W x 4 @ 2 ohm/75W x 4 @ 4 ohm - 14.4V
4-Channel Class D Full-Range Amplifier with Integrated DSP, 100 W x 4 @ 2 Ω / 75 W x 4 @ 4 Ω - 14.4V
Designed to simplify great audio, every MVi amplifier combines our advanced NexD2™ switching amplifier technology with an integrated, full-featured digital signal processor.
With our second-generation NexD2™ technology, the MV400/4i full-range amplifier outputs up to 75 watts per channel into 4 ohms, or 100 watts into 2 ohms. It can also be bridged into 4 ohms, producing up to 200 W x 2.
The NexD2™ full-range technology in this amplifier is DSP-controlled and features a reduced loop area design utilizing DirectFET™ outputs for outstanding fidelity, very low noise and exceptional efficiency. The amplifier chassis is ultra-compact, with all connections on one side, to greatly simplify installation into tight spaces.
Instead of traditional control knobs and switches, all amplifier adjustments and DSP functionality are configured via a compatible external device (PC, Tablet or Smartphone), with the appropriate JL Audio TüN™ Software application installed.
Amplifier includes: Power Connector (for 4 AWG wire), Analog Input/Pre-Out Harness, Speaker Output Harness, 6 ft A/B USB Cable
Features
Unprecedented, Onboard DSP Tuning Power!
PC or Mac®, via USB wired connection iOS® & Android® Devices, via Bluetooth® (with optional VXi-BTC).
2nd-Gen NexD2™ Switching Amplifier Technology
- DSP-synchronized power supply and output channels produce world-class sound quality with very low noise and distortion.
- Latest generation of DirectFET® MOSFET Output Devices
Compact Footprint
- Designed to fit in tight spaces
- Cast alloy chassis with marine-grade speaker connections and keyhole mounting design
- A perfect pairing with Subwoofer MVi amplifiers
Versatile, Differential-Balanced Analog Inputs
- Differential-Balanced Analog Inputs accept a wide range of signal levels (up to 16V RMS), and offer outstanding noise rejection for clean, clear audio.
- Depending on specific model, 4 or 6-Channels of Analog Pre-Outs, with fully independent DSP processing allow sharing DSP capabilities with other amplifiers in the system!
JLid™ System Command with Networking Capabilities (sold separately)
Proprietary JL Audio protocol provides control interface and all communication for MVi amplifiers and optional JLid™ accessories, including:
- VXi-BTC Bluetooth® Communicator: Adds wireless connectivity for a compatible iOS® or Android® device, permitting amplifier setup from these devices. (Functionality varies by model.)
- M-DRC-50 Controller:Push-button control with RGB indicator allows preset selection from the helm.
- MVi-HUB JLid-COMM and Network Bridge Hub: Provides network connectivity for up to six MVi amplifiers (one master and five slave amplifiers) for full-system DRC control and Preset selection.
