Our take on the JL Audio JLM6-8IB-S-GWGW-4 Gloss Sport Grille Subwoofer 8" - White

The JL Audio JLM6-8IB-S-GWGW-4 is an 8-inch marine subwoofer rated at 200 W RMS with a 4-ohm voice coil and a gloss white sport grille. It is built for open-air boats and other wet, sun-exposed installs, where its sealed motor and treated cone hold up better than car-audio subs. It is a passive driver, so it needs a separate amplifier and an enclosure or cutout. Against larger marine subs it gives up some low-end output, but it fits tight spaces and matches white gelcoat and upholstery.

Questions and answers

Does this subwoofer need an amplifier?
Yes. It is a passive driver with no built-in amp, so it needs an external amplifier rated for a 4-ohm load and about 200 W RMS.
Can it be used in a car?
It can, but it is built for marine use. The sealed motor and treated cone suit boats, and the white grille is styled for gelcoat interiors.
What size enclosure does it need?
It is an 8-inch sub, so it needs a sealed enclosure or cutout sized for an 8-inch driver. Check JL Audio's recommended sealed volume for this model before building.
Is it suitable for saltwater boats?
JL Audio rates its marine subs for wet, open-air use, but no speaker is fully salt-proof. Mount it where it gets some protection and rinse the area after saltwater exposure.
How much power can it handle?
It is rated at 200 W RMS. Pair it with an amp that delivers roughly that continuous power at 4 ohms rather than a much larger one.
Where is the JL Audio JLM6-8IB-S-GWGW-4 Gloss Sport Grille Subwoofer 8" - White cheapest?
