This bundle includes a JL Audio 12-Inch M7 Marine Infinite Baffle Subwoofer, Gunmetal & Titanium, Sport Grille - SKU: M7-12IB-S-GmTi-4, and a JL Audio XDM1000/1 XDM Series Monoblock Class-D Car/Marine Subwoofer Amplifier, 1000 W.
1x JL Audio 12-Inch M7 Marine Infinite Baffle Subwoofer, Gunmetal & Titanium, Sport Grille - SKU: M7-12IB-S-GmTi-4 - (M7-12IB-S-GmTi-4-K)
JL Audio M7-12IB-S-GmTi-4 12-inch (300 mm) Marine Subwoofer Driver, Gunmetal Trim Ring, Titanium Sport 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.

1x JL Audio XDM1000/1 XDM Series Monoblock Class-D Car/Marine Subwoofer Amplifier, 1000 W - (XDM1000/1)
JL Audio XDM1000/1 Monoblock Class D Car/Marine Subwoofer Amplifier, 1000 W x 1 @ 2 Ω / 600 W x 1 @ 4 Ω - 14.4V
This monoblock subwoofer powerhouse employs JL Audio's high-speed NexD™ switching technology to achieve unprecedented efficiency and amazing power output from a very compact chassis. The XDM1000/1 generates up to 1000 W of continuous power into a 2 ohm load (14.4V, 1% THD), making it a great choice to drive higher power subwoofer systems.
Designed for car or boat installations, the XDM1000/1 is built with marine-grade materials and features an exclusive, dual-mode input filter for noise-free performance in boats or cars. Automatic turn-on capability (via signal sensing or DC-offset sensing) is also onboard for easy factory system upgrades.
Intended specifically for subwoofer applications, the XDM1000/1 includes a variable slope low-pass filter with continuously variable cutoff frequency selection from 50-500 Hz and a defeatable infrasonic filter (30 Hz, 24 dB/oct.). With the addition of an optional HD-RLC or MHD-RLC (water-resistant) remote level controller (each sold separately), the amplifier's level can be adjusted directly from the driver's seat or captain’s chair.
Finished in a sleek, black powder-coat, all controls are protected beneath a gasketed, removable top cover for easy access.
