JL Audio M6 Marine Subwoofer, 4 Ohm, Transflective LED Option

Overview

The JL Audio M6 Marine Subwoofers is a family of marine subwoofer drivers offered in 8 in and 10 in sizes, each with a 4 ohm load and continuous power handling of 200 W (8 in) or 250 W (10 in). Configurations cover both infinite-baffle (free-air) installs and enclosed-use options, along with grille color and style choices that let you match the look across the boat.

These subwoofers are built for real cockpit and cabin conditions where gear sees spray, sun, and vibration. The front is protected from water ingress, but the rear terminals and wiring are not waterproof, so plan the mounting location and any enclosures so the back of the driver stays dry and protected from washdowns.

Key features

• 8 in model fit: 7.375 in mounting hole diameter with 5.00 in mounting depth.
• 10 in model fit: 8.875 in mounting hole diameter with 5.90 in mounting depth clearance.
• 4 ohm subwoofer drivers rated for 200 W continuous (8 in) or 250 W continuous (10 in) power handling.
• Range includes both infinite-baffle (free-air) and enclosed-use variants, depending on the part number.
• Transflective RGB LED lighting is available on select variants; the LED circuit runs on 10 to 14.4 V DC and uses a 750 mA fast-blow fuse per subwoofer on the LED positive lead.
• Grille color and style options include White Classic, White Sport, Titanium Sport, White Luxe, and Black Luxe.

Variants

This range is offered in many configurations, and the details that matter for fit and wiring are tied to the specific part number.

Across the lineup, variants differ by size (8 in or 10 in), installation type (infinite-baffle/free-air or enclosed-use), Transflective LED lighting (yes or no), and grille color/style. Audio wiring remains a standard two-conductor speaker connection, while LED-equipped versions add a separate 12 V lighting harness that needs its own fused feed.

Compatibility and fit

Start with the physical clearances. The 8 in driver uses a 7.375 in cutout and needs 5.00 in of depth behind the mounting surface. The 10 in driver uses an 8.875 in cutout and needs 5.90 in of depth clearance.

Mounting on a flat, solid surface helps the seal at the front and keeps vibration down. If you have a magnetic compass nearby, leave space so the subwoofer does not interfere with it.

Installation and setup

If the mounting location is exposed to weather or water, install on a vertical surface. A horizontal surface facing up can let water pool around the grille, which causes damage over time. For exterior installs, keep the driver well above the waterline and away from docks, pilings, and areas where it could be submerged.

Route speaker wires and any LED leads so they cannot chafe on sharp edges. When passing through panels, use rubber grommets and keep all connections insulated so nothing can ground out.

Electrical and system integration

On the audio side, these are 4 ohm subwoofer drivers. Match your amplifier and tuning to the driver size: 200 W continuous for the 8 in model and 250 W continuous for the 10 in model.

For LED-equipped versions, the lighting circuit is 12 V (10 to 14.4 V DC) and requires an inline 750 mA fast-blow fuse per subwoofer at the power-source end of the LED positive lead. Use at least 20 AWG wire for the LED power and ground runs, and do not connect the LED lighting to 24 V systems or to navigation light circuits.

Use cases on board

This series suits boats where you want low-frequency support that holds together in open-air listening, such as cockpit seating zones, helm areas, or salon systems that need more bottom end. LED variants also make sense when you already have an accent-lighting plan and want the audio zones to match the rest of the boat at night.

Maintenance and care

Wash the exposed surfaces with mild soap and rinse with fresh water. Avoid high-pressure spray and do not allow water to soak the rear of the driver, terminals, or wiring.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
