Fusion FM-Series 7.7" 200 W marine speakers black flush-mount round

These Fusion FM marine speakers have a maximum (peak) power output of 200 W.

The RMS (Root Mean Square) power of these speakers is 50 W.

These speakers are round with a 7.7-inch diameter, which corresponds to a mounting diameter of 165 mm (6 1/2 inches).

Yes, these speakers are rated IP65 (per IEC 60529 standard) for dust and water ingress from the front. This means they are dust-tight and protected against water jets.

The frequency response of these speakers is 80 Hz to 18 kHz.

These speakers are designed to operate within a temperature range of 0 to 50 °C (32 to 122 °F).

To clean the speakers:

Clean any salt residue with a damp cloth soaked in fresh water.Use a mild detergent to remove significant salt buildup or stains.Warning: Do not use harsh or solvent-based cleaners, and avoid high-pressure water sprays as they may damage the product and void the warranty.

The required cutout diameter (clearance) for installing these round speakers is 165 mm (6 1/2 inches).

The minimum mounting depth (clearance) required for these speakers is 83 mm (3 1/4 inches).

The mounting panel thickness must be between 3 mm (1/8 in) and 25 mm (1 in) for correct installation.

For installation, you will need:

A Phillips screwdriverA torque screwdriver with a Phillips bitA saw or utility knife to cut the surface materialMarine-grade tinned copper speaker wire, 16 AWG (1.3 to 1.5 mm²)Marine sealant (such as 3M™ 4200 or 5200)Female spade connectors, 4.8 mm and 6.3 mm (recommended)

Use 16 AWG (1.3 to 1.5 mm²) tinned marine-grade speaker wire to connect these speakers to your stereo or amplifier. Speaker wires are terminated with male spade connectors; using female spade connectors (not included) is recommended for optimal connection.

For these FM-F77 speakers, the polarity is as follows:

The white wire corresponds to the positive pole (+) and uses a 6.3 mm spade connector. The white wire with a black stripe corresponds to the negative pole (-) and uses a 4.8 mm spade connector. Ensure these polarities are respected when connecting to your stereo system or amplifier.

Yes, it is recommended to apply marine sealant, such as 3M™ 4200 or 5200, to the speaker and mounting surface to ensure proper waterproofing.

Yes, after initially turning the screws with a Phillips screwdriver to extend the mounting legs, you must use a torque screwdriver to hand-tighten the screws to 1.0 Nm (0.74 lbf-ft). Using power tools to fully tighten the screws may damage the speaker housing.

The nominal impedance of these marine speakers is 4 Ohms.

It is recommended to use an amplifier with an RMS power output of 20 to 150 W per channel for these speakers.

All Fusion products bearing the True-Marine warranty seal are covered by a 3-year limited global consumer warranty.

The warranty may be voided in the following situations:

Damage caused by exposure to water or other liquids at the rear of the speaker. Use of aggressive or solvent-based cleaners on speakers. Damage resulting from high-pressure water spray during boat cleaning. Failure to follow installation instructions, particularly regarding protection of terminals and connections against grounding or short circuits.
