Marine amplifier MV600/1

The JL Audio MV600/1 is a marine Class D monoblock amplifier, specifically designed for subwoofer amplification. It integrates JL Audio's second-generation NexD2™ high-speed switching technology.

The JL Audio MV600/1 is a monoblock amplifier for subwoofer delivering 600 watts of power.

NexD2™ technology is the second generation of JL Audio’s high-speed switching technology. It is designed to deliver reference-grade low-frequency amplification with exceptional efficiency.

Yes, this amplifier is specifically designed for marine environments. Its outer casing is designed to dissipate heat, and it can achieve an IPX2 water resistance rating when mounted vertically with connections facing downward.

The amplifier’s external housing is designed to dissipate heat. For optimal cooling, it must be exposed to as large a volume of air as possible. If the amplifier is installed in an enclosed compartment, it should be ventilated with a fan and at least 2.5 cm (1 inch) of clearance must be left above the housing.

To achieve an IPX2 water resistance rating, it is recommended to mount the amplifier vertically, with all connections pointing downward. Wiring must be routed to direct potential condensation and moisture away from the amplifier.

The "+12 VDC" and "Ground" connections of the amplifier are designed to accept copper cable up to 4 AWG. Tinned copper cable is the best choice for marine installations, and 4 AWG is the minimum recommended size. Copper-clad aluminum (CCA) cables are not recommended.

A suitable fuse or circuit breaker (sold separately) is essential for the boat's safety. It must be installed within 18 cm (7 inches) of the battery pole connection or in accordance with marine industry standards. If this amplifier is the only device connected to this main wire, use a 50 A rating.

The ground connection must be made to the negative terminal of the battery. Alternatively, a properly installed and positioned DC ground busbar near the battery can be used. All ground connections (source unit and amplifiers) must be made at the same point.

To connect these wires, unscrew the adjustment screws on the connector using the provided hex keys. Strip approximately 10 mm (3/8 inch) of insulation from the end of each wire and firmly insert the stripped wire into the power connector receptacle. Tighten each adjustment screw securely, then plug the power connector into its receptacle on the amplifier.

Install the amplifier in a dry, well-ventilated location.Never submerge it or expose it to high-pressure water jets.Avoid direct exposure to the elements, the engine compartment, or areas of extreme heat.Mount it securely to prevent detachment.Check before drilling to avoid damaging vital boat components.Do not route the system wiring outside or under the boat.Protect all wires from sharp edges using cable ties, grommets, and conduits.

This amplifier is designed to operate with 12 V DC negative-ground electrical systems.

No, using this amplifier in vehicles with a positive ground or voltages other than 12V DC can damage the product and will void the warranty.

The amplifier is configured using an external device (PC, tablet or smartphone) on which the appropriate JL Audio TüN™ application is installed. A USB A/B connection is available for configuration with a computer.

The JLid-COMM port allows connection of optional accessories such as the MVi-HUB, M-DRC-50 or VXi-BTC.

Yes, using this product in vessels with a positive ground and/or voltages other than 12V DC may damage the product and will void the warranty.

To perform a factory reset, press and hold the reset button for 7 seconds using a small pin. This will erase all user settings and the amplifier will revert to its factory defaults.

To restart the amplifier while keeping your previous user settings, briefly press and release the reset button using a small pin.
