1x JL Audio MHD750/1:Monoblock Class D Wide-Range Marine Amplifier 750W - (MHD750/1)
JL Audio MHD750/1
Monoblock Class D Marine Wide-Range Amplifier, 750 W x 1 @ 1.5-4 Ω
This ultra-compact monoblock amplifier employs our Single-Cycle Control switching design and R.I.P.S. technology to deliver 750 W of clean power into any impedance between 1.5 and 4 Ω, giving you the highest degree of flexibility in designing your subwoofer system. Tight power supply regulation keeps distortion down and maximizes your bass quality. From a pure sound quality perspective, we invite you to compare the real-world, in-car performance of this amplifier to any other amplifier on the market, of any type, at any price.
While targeted primarily to subwoofer applications, the HD750/1 is a wide-range amplifier and can also be used to drive high-performance mid-range speaker systems.
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.

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.
