Installation Applications

This amplifier is designed for operation with 12 volt DC, negative-ground electrical systems. Using this product in vessels with positive ground and/or voltages other than 12V DC may result in damage to the product and will void the warranty. This product is not certified or approved for use in aircraft.

Planning Your Installation

It is important that you take the time to read this manual thoroughly and that you plan your installation carefully. It is very easy to damage electrical systems in modern vessels. Never assume that you have found appropriate wires without consulting a reliable wiring diagram or without analyzing using proper test equipment. If you are uncomfortable or unfamiliar with diagrams or testing methods, please enlist the services of your authorized JL Audio dealer to perform the installation. Your authorized dealer has the training, expertise and installation equipment to ensure optimum performance from this product. The following are some considerations that you must take into account when planning your installation.

Safety Considerations

• Install your amplifier in a dry, well-ventilated location that does not interfere with factory installed systems.
- This product should never be submerged under water or subjected to high pressure water spray. - Do not install where it will be directly exposed to the elements, or in the engine compartment, or in any areas of extreme heat. Areas exposed to a heater or hot air should also be avoided.
- When selecting a mounting location, consider the orientation of the amplifier and its associated connection. If possible, position the amplifier vertically, with all connections pointing downward. Wiring and cables should be routed to direct potential condensation and moisture away from the amplifier.
- Securely mount the amplifier so that it does not come loose in the event of a collision or sudden jolt, or as a result of repeated vibrations during normal operation.
- Check before drilling to make sure that you will not be drilling into an exterior panel/hull, fuel tank, fuel line, wiring harness, or other vital system.
- Do not run system wiring outside or underneath the vessel. This is an extremely dangerous practice, which can result in severe damage/injury.
- Protect all system wires from sharp edges by carefully routing them, tying them down and using grommets and loom, where appropriate.
- Secure all wiring as needed, using cable ties or wire clamps to protect them from moving parts and sharp edges.

Power Connector

The MV1000/1's "+12 VDC" and "Ground" connections are designed to accept up to 2 AWG copper wire. Note: Copper Clad Aluminum (CCA) wire is not recommended. Tinned copper power wire is the best choice for marine installations. 4 AWG is the minimum copper wire size for this amplifier.

To connect the power, ground and remote turn-on wires to the amplifier, back out the set screws on the connector using the supplied hex wrenches. Strip back 3/8 inch (10 mm) of insulation from the end of each wire and insert the bare wire into the receptacle on the power connector plug, seating it firmly so that no bare wire is exposed. While holding each wire in place, tighten each set screw firmly, taking care not to strip the head of the screw. Install the power connector by plugging it into the amplifier's power connector receptacle, pushing firmly.

A. +12 VDC: Run copper wire from the positive (+12V) battery post to the amplifier mounting location. If additional amplifiers are being installed, run the appropriate gauge copper wire for the combined, maximum current draw, and install a fused distribution block near the amplifiers.
8. An appropriate fuse or ignition-protected circuit breaker (sold separately) at the main power wire(s) is vital for vessel safety. This must be installed within 7 inches (18 cm) of the battery post connection or in compliance with marine industry standards. If this is the only device connected to this main wire, use a 80 A value. Do not install the fuse or close the circuit breaker until the power wire has been securely connected to the amplifier and all other connections have been made.
C. Ground: This connection should be made to the NEGATIVE battery post. Alternatively, an appropriately equipped and positioned DC ground bus bar near the battery may be used. All ground connections (source unit and amplifiers) should be made at the same location.
D. Remote: This connection should be made to the source unit's positive (+12V) remote turn-on output. If your source unit does not have a dedicated remote turn-on output, the amplifier's remote turn-on connection can be connected to +12V via a switch that derives power from an ignition-switched circuit.

Input Section

Two female RCA jacks feed a differential-balanced input section, providing a high degree of input flexibility, and retaining superior noise rejection. This type of input architecture also allows the MV1000/1 to cleanly accept any analog audio signal up to 8 VRMS, without using a line-output converter.

Pre-Outs

Two female, RCA jacks deliver line-level, analog audio outputs (Max 4 V RMS) that are compatible with most types of aftermarket equipment.

Cooling Efficiency Considerations

The outer shell of your JL Audio amplifier is designed to remove heat from the amplifier circuitry. For optimum cooling performance, this outer shell should be exposed to as large a volume of air as possible. Enclosing the amplifier in a small, poorly ventilated chamber can lead to excessive heat build-up and degraded performance. If an Installation calls for an enclosure around the amplifier, we recommend that this enclosure be ventilated with the aid of a fan. In normal applications, fan-cooling is not necessary. When mounting the amplifier in an enclosed compartment, make sure there is at least 1 inch (2.5 cm) of space above the amplifier's outer shell to permit proper cooling.

Mounting Considerations

MV amplifiers are equipped with keyhole style mounting holes to simplify installations in confined spaces or vertical-mount applications. Mounting screws may be preinstalled, allowing amplifier connections to be made prior to securing in its final location. See diagram at right.

When selecting the installation location, consider the mounting orientation of the amplifier and its associated connections. If possible, position the amplifier vertically, with all connections pointing downward. Wiring and cables should be routed to direct potential condensation and moisture away from the amplifier. When installed in this manner, the amplifier achieves an IPX2 water-resistance rating.

Speaker Output Harnesses

Connect the speaker output leads to the corresponding speaker wires. The harness and companion cable are equipped with water-resistant connectors for maximum connection integrity in marine environments.
