1x JL Audio MHD-RLC: Water-Resistant Amplifier Remote Level Control and Cable - (MHD-RLC)
JL Audio MHD-RLC - Water-Resistant Remote Level Control for Select JL Audio Amplifiers The MHD-RLC remotely controls the Bass Level of the following JL Audio amplifiers: HD-Series: All models XD-Series: All models MHD-Series: All models M-Series: All models When the MHD-RLC is connected to the above amplifiers, it acts as an attenuator on the input gain of the amplifier and is used to adjust the overall level of the amplifier from the front of the vehicle. The MHD-RLC kit includes the rotary control with a black ABS knob, mounting hardware and one 16.4 ft. (5 m) cable. A satin-finish aluminum knob can be purchased separately.
1x JL Audio MHD750/1:Monoblock Class D Wide-Range Marine Amplifier 750W - (MHD750/1)
JL Audio MHD750/1: Monoblock Class D Wide-Range Marine Amplifier 750W
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 ultra-low and maximizes your bass performance. While targeted primarily to subwoofer applications, the MHD750/1 is a full-range amplifier and can also be used to drive high-performance mid and high frequency 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.
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.
