Marine subwoofer Signature Series 3i Sport gray 10" 600 W with CRGBW LED

This Fusion Signature Series 3i marine subwoofer has a maximum power output of 600 W.

This is a 10-inch marine subwoofer.

Yes, this subwoofer is a True-Marine™ product, meaning it has undergone rigorous environmental testing in harsh marine conditions to exceed industry standards for marine-grade products.

This subwoofer is gray and part of the Sports edition.

The subwoofer’s front face is protected against water infiltration. However, the rear section of the subwoofer, including all components and connected wires, is not waterproof and must be shielded from moisture exposure.

Moisture exposure on the subwoofer’s rear section can cause component failure and void the warranty.

For installing this subwoofer, you will need the following tools:

An electric drill and drill bits suitable for the surface material.
A jigsaw or rotary tool for cutting the surface.
A Phillips screwdriver.
Wire strippers.
Marine-grade tinned copper speaker wire, 12 AWG (3 to 4 mm²) or thicker.
Marine sealant (optional).
Solder and waterproof heat-shrink tubing or waterproof butt connectors with heat-shrink tubing (optional).

The cutout required for installing this 10-inch subwoofer is Ø 223 mm (8.75 inches).

When choosing the mounting location, consider the following points:

Select a location that protects the rear of the subwoofer from exposure to moisture. Ensure there is sufficient space for the mounting depth of the subwoofer. Prefer a flat and vertical mounting surface for better waterproofing. If the subwoofer is mounted outdoors, it must be well above the waterline and protected from potential damage. Protect the subwoofer wires from sharp objects and use rubber grommets when passing wires through panels.

Use marine-grade 12 AWG (3 to 4 mm²) or thicker tinned copper speaker cable to connect the subwoofer to the amplifier.

For LED lighting, it is recommended to install a Fusion CRGBW wireless remote control module. If you are not using it, you can connect the LED wires directly:

Connect the black wire of the LED harness to the positive terminal (+) of a 12 V DC power source. Connect the negative wire (-) of the same power source to one or more colored wires of the LED harness to select the desired color. Unused LED wires on the harness must be insulated to prevent short circuits. Use 20 AWG (0.5 to 0.75 mm²) wire or thicker for LED connections.

You must install a 300 mA inline fast fuse on the positive power wire of the LEDs, near the power source, to protect the LEDs and the speaker from excessive electrical current. The fuse must be in a marine-rated fuse holder.

It is important to use a watertight connection method when connecting speaker wires to the wiring harness. You can use:

Solder and watertight heat-shrink tubing.Watertight butt-style heat-shrink connectors.Marine sealant (optional) for custom installations. Additionally, wiring harness connections must be secured to prevent strain on internal wires, for example with cable ties.

When drilling mounting holes, follow these precautions:

Always check what is on the other side of the surface to avoid damaging the boat. Do not use the subwoofer’s holes as a guide for pilot holes, as this could damage it. Use a drill bit of the appropriate size for the mounting surface and screw type.

This subwoofer is compatible with a suitable marine amplifier. Ensure the chosen amplifier is matched to the power and electrical requirements of the subwoofer to guarantee optimal performance.

A Fusion CRGBW wireless remote control module is recommended for full control of the LEDs (on/off, color changes, effects). However, it is not mandatory. You can hardwire the LEDs for a static color.

Yes, this subwoofer can be integrated into most existing marine audio systems, provided the electrical specifications (power, impedance) are compatible with your amplifier. Standard wiring is included to simplify installation.

The limited warranty does not cover:

Cosmetic damage (scratches, scuffs, dents).Consumable parts, unless the damage is due to a manufacturing defect.Damage caused by an accident, abuse, misuse, water (including exposure of the rear of the subwoofer), flooding, fire, or other external causes.Damage resulting from service performed by a provider not authorized by Garmin.Products modified or altered without Garmin’s written authorization.Damage related to the use of power or data cables not supplied by Garmin, or uncertified power adapters.
