1x JL Audio MHD900/5:5 Ch. Class D Full-Range Marine System Amplifier 900 W (MHD900/5)
JL Audio MHD900/5
5-Channel Class D Marine System Amplifier, 100 W x 4 + 500 W x 1
Thanks to its ability to act as a "one-box solution", the MHD900/5 is ideal for installations where space is at a premium and sound quality is the paramount goal.
While extremely compact, this amazing amplifier will comfortably drive a complete high-performance car audio system: that is, four satellite speaker systems and a subwoofer system... with a very serious 900 watts of power!
Using our Single Cycle Control switching design and R.I.P.S. technology, the MHD900/5 delivers 100 W x 4 to its four main channels, plus a very meaty 500 W to its subwoofer channel. Thanks to R.I.P.S., high power can be delivered over a wide range of load impedances, while the tight power supply regulation keeps distortion down, maximizing sound 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.
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 7.7-Inch M6 Marine Coaxial Speaker System, RGB LED, Gloss White, Sport Grille - SKU: M6-770X-S-GwGw-i (M6-770X-S-GwGw-i)
JL Audio M6-770X-S-GwGw-i
JL Audio 7.7-Inch M6 Marine Coaxial Speaker System, RGB LED, Gloss White, Sport Grille - SKU: M6-770X-S-GwGw-i
M6 Loudspeakers fulfill JL Audio’s commitment to raise the bar with each product generation. The JL Audio engineering team has completely reinvented the premium marine loudspeaker, with major improvements in performance, precision and durability. Offered in multiple sizes and cosmetic options, most models are also available with a brilliant, new lighting technology.
Coaxial Speaker Technology
Every M6 coaxial loudspeaker starts with a long-excursion woofer designed with JL Audio’s proprietary motor, suspension and cone modeling systems to yield superior frequency response, smooth mid-range dispersion and linear performance at all listening levels. JL Audio’s acoustics laboratory in Miramar, Florida performs extensive testing on multiple generations of prototypes to refine every design and extract maximum performance.
Matching Silk-Dome Tweeters
Since the different size woofers in the M6 coaxials have different upper frequency response limits, each size pairs with its own specially designed, matching silk dome tweeter (0.8, 1.0, or 1.25-inch diameter). Each of these tweeters is precisely tuned via a rear cavity that optimizes its mid-range extension to seamlessly transition with its matching woofer. The result is smooth, evenly dispersed sound throughout the critical crossover region, making the overall sonic presentation clean and clear.
Advanced Built-In Crossover Networks
Crossover networks are a critical part of the M6 coaxial speakers’ acoustic design and are considerably more sophisticated than those used in most marine coaxial speakers. The M6-650X employs a 1st order low-pass and 2nd order high-pass filter, while the M6-770X and M6-880X apply a 2nd order low-pass and 3rd order high-pass filter. Each crossover network also employs an electronic tweeter protection circuitto minimize the possibility of tweeter failure.
The multiple components required inthese crossovers are laid out on a ring-shaped circuit board that is built into each speaker’s terminal assembly, ensuring that the crossover is secure and protected from the elements.
Transflective™ LED Illumination
Optional on most M6 models is JL Audio’s Transflective™ LED technology. By emitting light from multiple LEDs through our specially engineered cone material, this patent-pending breakthrough delivers a beautiful cone illumination effect, with no hot spots or reflections on the cone surface.
Choose from seven fixed lighting colors or control the color and intensity of the lighting actively using a lighting controller accessory (sold separately). Separate 12V wiring is required to power the illumination.

Advanced Subwoofer Technologies
Offered in 8-inch and 10-inch diameters, M6 subwoofers continue JL Audio’s tradition of building low-frequency drivers that impress, not only with their output capability, but also with the quality and balance of their sound. FEA-optimized motor and suspension designs are optimized for infinite-baffle installation (IB models), or for installation into small sealed enclosures (W models). Choose the right one for your application and it will reward you with powerful, low-distortion sub-bass that takes your marine audio experience to a higher level.
