• Crossover Networks: Natural woofer roll-off with 2nd order high-pass filter on tweeter. Solid-state tweeter protection circuit.

Included Components and Parts:

• Two Marine Coaxial Loudspeakers
• Two Polymer Woofer Grilles (attached to the speaker)
• Two Treated Silk Dome Tweeters (mounted to grilles)
• Two 2nd order high-pass filters (mounted to grilles)
• Twelve #8 x 1 1/8-inch (29 mm) Phillips-head stainless-steel screws for speaker mounting
• Twelve #8 stainless-steel washers for speaker mounting
• Mounting Template

  One Pair Black (Gunmetal Sport Models Only)

LED Equipped Models: Built-in, RGB LED lighting delivers beautiful accent illumination. LED functionality requires separate wiring at each speaker location. Adjustable control of RGB lighting requires the use of an RGB lighting controller (sold separately). For optimal performance, we recommend using the
JL Audio marine lighting controller (MLC-RW).

Caution

Prolonged exposure to sound pressure levels in excess of 100dB can cause permanent hearing loss. This high-performance speaker can exceed this level. Please exercise restraint in its operation in order to preserve your ability to enjoy its fidelity.

Warning
It is absolutely vital that your coaxial speaker system is connected as shown in this manual. Failure to connect the system as shown will result in damage to your speakers which is NOT covered under warranty. Do not substitute different crossover networks. Do not attempt to remove the tweeter or lighting LEDs from the grille. The tweeter and LEDs are permanently fixed to the grille and their wiring is permanently attached to the speaker frame. Attempting to remove the grille, tweeter or LEDs will damage the speaker and this damage will not be covered under the warranty.

Caution
When installing speakers in your vessel, it is extremely important to secure them firmly. This applies not only to the speakers themselves but also to any structure they are mounted to. If not firmly attached, the speakers can become dangerous projectiles in a collision. Please review the mounting information carefully and use the supplied marine-grade hardware to mount this product.

Warning
While these speakers are designed to be water and spray-resistant, they are not designed to be submerged or to withstand high-pressure water spray. Do not install on submersibles, personal watercraft, or any other vessel likely to be underwater at any time. Please exercise care when washing your boat to avoid damaging your speaker. Avoid contact with harsh chemicals or cleaning agents to prevent damage to the speaker’s finish that will not be covered under the warranty. Wash with mild soap and rinse with fresh water only

INTEGRATED RGB LED LIGHTING
Illuminated speaker models are outfitted with multi-color LEDs to produce vibrant accent lighting. Embedded within each speaker grille are six RGB LEDs, positioned and concealed from direct sight. Wire leads exiting from behind the grille include LED connections. Refer to the table below for individual RGB wire connection info

Adjustable control of RGB lighting may be achieved with the use of an RGB lighting controller (sold separately). Refer to the instructions of your RGB lighting controller for specific connection info. Note: When selecting an RGB lighting controller, make sure that the total amperage demands of all LED circuits does not exceed the output capacity of the controller. Refer to the table below for the individual current draw amounts and sum (add) the total. For optimal performance, we recommend using the JL Audio marine lighting controller (MLC-RW).

RGB LED SPECIFICATIONS

DIRECT LED WIRING
Alternatively, you may hard wire individual leads or a combination of leads to achieve up to seven different LED color assortments. Refer to the table below for the wire colors used to achieve specific LED colors.
Note: Wiring connections at each speaker location are required for LED functionality

Combine selected wires from all speakers and connect to negative ground or to the negative (–) battery post.

Green| Green
Blue| Blue
Yellow| Red and Green
Pink| Red and Blue
Aqua| Green and Blue
White| Red, Green and Blue
Combine all YELLOW (+12V) leads together (parallel) and connect to a switched +12V supply. See below for additional info.

LED WIRING CONSIDERATIONS

• Do not connect to 24V electrical systems.
• Do not connect the speakers’ LED lights to the vessel’s navigational lighting circuits.
• For short-circuit protection, we recommend installing a fuse (not included) at EACH speaker’s YELLOW (+12V) LED power connection lead. Refer to the RGB LED Specifications table (at left) for recommended fuse ratings.
• We recommend a minimum of 16AWG wire size for each speaker’s LED connection circuits.
• In addition to the above, we recommend activating the speakers’ LEDs thru a cabin/interior lighting circuit that supplies +12V via an existing switch. If an existing switched circuit is not available, you may install a dedicated toggle/rocker style switch that will supply positive (+12V) power. Fuse this main +12V connection according to the total amperage demands of all LED circuits. Refer to the RGB LED Specifications table (at left) for individual current draw amounts and recommended fuse ratings.

TWEETER PROTECTION
The crossover networks are equipped with an advanced electronic tweeter protection circuit designed to minimize the possibility of tweeter failure. This electronic device monitors the current going to the tweeter and will disconnect the tweeter from the signal when it senses overload. Should this occur while listening to the audio system, simply reduce the volume for a few seconds and the protection circuit will reset itself automatically.

BEFORE YOU BEGIN INSTALLING

• Check with your local waterway authority for any regulations regarding the use of accent/speaker lighting on your vessel.

• Turn off the audio system. It is also advisable to disconnect your battery system whenever performing installation work.

• Before cutting, drilling or inserting any screw, check clearances on both sides of the planned mounting surface. Also check for any potential obstacles, such as wiring harnesses, fuel lines, hydraulic lines, etc. Check both sides of the vessel before cutting any holes.

• If you are running cables through bulkheads, drill holes for the cable and use a urethane
  or plastic grommet to protect the wire from chafing in the hole. Make sure that the cables will clear any mechanical devices in the boat and secure them with wire ties.

• Wear protective eyewear at all times and a dust mask and gloves when drilling or cutting.

INSTALLING THE SPEAKERS
These speakers are specifically designed for infinite-baffle applications. In other words, this means that they are designed to operate without an enclosure behind them.
Once mounting locations have been established, run speaker cables from the amplifier outputs to the mounting locations. For LED-equipped models, now is also a good time to run wires to each speaker location for LED activation.

INSTALLATION PROCEDURE
Diagrams A & B shows typical installation procedures into a fiberglass panel, using the supplied hardware. Always follow proper safety procedures. Use eye protection at all times and a dust mask and gloves when cutting.

1. Choose a flat mounting surface that has sufficient depth and air space behind it to accept the speaker.
2. Using a hole saw or jigsaw, cut a mounting hole for your respective speaker model (see “Mounting Hole Diameter (D)” specifications).
3. If using a jigsaw, tracing the supplied mounting template will provide you with an accurate line on which to cut.
4. Place the speaker in the hole (or use the mounting template) and mark the screw hole locations using a sharp, pointed tool.
5. Remove the speaker and drill a pilot hole (see the Pilot Hole Recommendations chart on page 6) in each of the screw locations. It is also advisable to use a hand-driven countersink tool on each hole to further inhibit gel-coat cracking of fiberglass panels.
6. Connect the speaker wires from the amplifier to the woofer connections
7. If equipped, connect the LED circuit leads
8. Place the speaker into the opening.
9. While holding the speaker firmly in its mounting location, place a #8 screw (with washer) at each pilot hole location and snug in a criss-cross pattern, then tighten with a hand screwdriver in a criss-cross pattern.

Non-standard installations may require different hardware. Always use marine- grade, stainless-steel fasteners to ensure a secure, reliable installation.
