2x JL Audio OEM 12-Inch M7 Marine Infinite Baffle Subwoofer, RGB LED, Gloss White, Classic Grille - SKU: M7-12IB-C-GwGw-i-4 - (OD-M7-12IB-C-GwGw-i-4)

JL Audio M7-12IB-C-GwGw-i-4 12-inch (300 mm) Marine Subwoofer Driver with Transflective™ LED Lighting, Gloss White Trim Ring, Gloss White Classic Grille, 4 Ω

Engineered as the reference standard for marine subwoofer performance, the M7-12IB is capable of producing staggering amounts of jaw-dropping bass in infinite-baffle applications.

Built to withstand real-world marine duty, this M7-12IB is designed to operate without a dedicated enclosure. It boasts a monstrous 4-inch voice coil and rugged suspension system to deliver outstanding linear excursion for high output and power handling.

M7-12IB is best used with amplifier power in the 200W – 600W range and is optimized to operate with a large volume of air behind it (at least 3 cu. ft. / 84.95 l).

Like all JL Audio marine speakers, this driver is built to withstand a real saltwater marine environment and deliver years of listening enjoyment.

The patent-pending Transflective™ RGB LED technology emits a smooth lighting effect through the woofer cone, with a choice of several lighting colors. Add an optional RGB controller to create thousands of color variations. Professional installation is strongly recommended.

1x JL Audio MHD600/4:4 Ch. Class D Full-Range Marine Amplifier 600 W - (MHD600/4)

JL Audio MHD600/4: 4 Ch. Class D Full-Range Marine Amplifier 600 W

4-Channel Class D Marine Full-Range Amplifier, 150 W x 4 @ 1.5-4 Ω

This compact, multi-channel powerhouse employs our Single-Cycle Control switching design and R.I.P.S. technology to deliver 150 W x 4 or 300 W x 2. Tight power supply regulation keeps distortion down and maximizes sound quality.

When using the MHD750/1 to drive a subwoofer system, the MHD600/4 is the ideal satellite amplifier, delivering huge dynamics with pristine resolution. It can also be deployed, on its own, as a very capable 3-channel system amplifier with 150W x 2 to the satellites and 300W x 1 to a subwoofer system.

This marine amplifier features white and gray powder-coat finishes, a gasketed cover for the controls and stainless steel hardware for durability in the marine environment.
