JL Audio MX500/4 4-Channel Class D Marine Amplifier + JL Audio M3-650X-GW-I x2 Pairs 6.5″ Marine Speakers with LEDs
Amp Highlights
4-Channel Class D Full-Range Amplifier, 125 W x 4 @ 2 Ω / 70 W x 4 @ 4 Ω – 14.4V
Generating a solid 70W x 4 into 4 ohms (14.4V, 1% THD), the MX500/4 is fully bridgeable, so it can be used as a 3-channel amplifier, or as a 2-channel amplifier producing a potent 250W x 2 into 4 ohms.
Other features include independent front and rear crossovers with selectable full-range, high-pass or low-pass filter controls and a dual-range input section that accepts a wide range of input voltage levels, from line-level all the way to high-power speaker level signals.
This amplifier features a black powder-coated finish, a gasketed cover for the controls and stainless steel hardware for durability.

Speaker Highlights
Great sound and life on the water. These 650X-S-Gw-i 6-1/2″ marine speakers combine durable, marine-ready design, outstanding audio performance, and the cool look of subtle blue lighting. Supplied with plenty of power, these speakers can overcome that wicked combination of wind, water, and engine noise. Plus, the built-in LED lighting brightens up any nighttime cruise.
The weatherproof cone is suspended in a durable synthetic rubber surround for great sound and long life, and the UV-resistant polymer basket surrounds and protects the entire structure. The 3/4″ treated silk dome tweeter renders brilliant highs, and it’s mounted directly to the white “Sport” grille for optimal sound radiation. The high-quality 2-way crossover mounted to the woofer basket ensures the woofer and tweeter work in perfect concert.
You can mount these sharp-looking 6-1/2″ speakers in your boat’s cockpit or bulkhead walls, either as stand-alone or in conjunction with a subwoofer.
