Jl Audio M6 8 in Marine Subwoofer, 200W RMS, 4 Ohm, Infinite Baffle, White Luxe Grille

Overview

The Jl Audio 010-03508-00 is an 8-inch marine subwoofer for infinite-baffle installs with a white trim ring and a white low-profile Luxe grille.

It is a 4 O driver rated for 200 W RMS, with a recommended amplifier range of 50 to 200 W RMS. Sensitivity is 86.8 dB (1 W/1 m), which helps when you are balancing bass output with cockpit and cabin speakers.

For fit, the cutout is 8.625 in (219 mm) and the overall diameter is 10.25 in (260 mm). Plan on 6.30 in (160 mm) of clearance behind the mounting surface, plus about 0.48 in (12 mm) of grille protrusion in front.

Installation and setup

Infinite-baffle mounting means the back of the subwoofer vents into a large cavity instead of a sealed box. On boats, common locations are a helm side panel, cockpit seating base, cabin settee face, or a bulkhead that opens into a locker. The goal is to keep the front wave separated from the back wave, so the mounting panel needs to be stiff, well-sealed, and free of air leaks.

Leave room behind the driver for wiring and airflow and avoid packing gear tightly against the basket. If you are installing it in a dedicated sealed or ported enclosure instead of free air, use a rigid box plan sized for an 8-inch subwoofer and mount it where it stays dry.

Compatibility and system integration

This is a 4 O subwoofer, so verify your amplifier channel is stable at 4 O and can deliver clean power in the 50 to 200 W RMS range. Most systems come together when the sub channel is low-passed and the main speakers are high-passed, so smaller speakers are not working hard on deep bass.

Use tinned copper speaker wire with secure terminations and route it away from high-current power runs when possible. For open-cockpit installs, mount it where water does not sit against the grille, and make sure the space behind the panel has a path to drain and dry out.

Use on board

This subwoofer is a good match when you want more low end but do not have room for a large box. It fits well on center consoles, cruisers, and sport boats that have usable volume behind a bulkhead or inside a seat base, including setups that see regular vibration, spray, and sun.

Maintenance and care

Rinse salt off the grille during washdowns and avoid harsh cleaners on the cone and surround. If you plan to repaint the trim ring or grille, remove them first so paint does not clog the mesh or build up on the mating surfaces.

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.
