    Our JL Audio M3 7.7" 4 Tower Speaker Package includes the four, JL Audio 7.7", M3 tower speakers, a JL Audio 800 watt, 8 channel, M-series amplifier, an amp wiring kit, and a 6 meter long, 2 channel, marine RCA cable. Outside of the mounting hardware and speaker wire, this kit includes everything you need to add 4 JL Audio tower speakers to your existing stereo system.

    The JL Audio 7.7" M3 tower speakers deliver the performance, quality, durability, and reliability you expect from JL Audio marine products. The enclosures are availabe in white sport, white classic, and gunmetal sport speaker grilles. The white models feature a gloss white enclosure while the titanium speakers have a satin black enclosure. Both the white sport and titanium sport options are available with RGB LEDs. The M3 speakers can handle 70 watts of RMS power and match up perfectly with the M-Series amplifiers. The .75", specially-treated, silk dome tweeter delivers smooth, mid-bass response and a richer, warmer, more well balanced output than other marine speakers that use metal and plastic tweeter materials.

    The M-series, 400 watt, 4 channel amplifier delivers the perfect amount of RMS powr for the 7.7" M3 ETXv3 tower speakers. The JL Audio M-series amplifiers are among the most popular marine amps in the world thanks to their unrivaled performance, clean yet powerful output, and superior thermal management. When running a 4 ohm load, these amps can deliver power to your speakers, while playing loud, all-day, regardless of the outside temperature. The Class-D circuitry combined with JL's signal processing make the M-series amps a no-brainer when it comes to powering your boat's stereo system. If you want to over-power your speakers, or if you have additional tower speakers that you are adding to, you can upgrade to the M800/8v2. With this setup, you can power your additional speakers or you can bridge the 8 channel amplifier, keep the gains down low, and take some of the stress off of the the amplifier if you use your boat in really hot weather, you play your music really loud, and you play your system all day long.

    The Stinger marine amp kit uses the traditional marine colors of red and yellow and has siamese, 4 AWG power wire. The 4AWG wire insulation is connected like what you typically see from standard speaker wire and the power and ground wires are the same length. This allows you to easily run your power wires from your amplifier to your battery and you only have to pull 1 wire. The amp kit includes a marine-grade, 80 amp fuse holder and everything else you should need for power. The amp kit does not include a circuit breaker, but you can add a JL Audio or Stinger circuit breaker if you choose to go that route. For the RCA cable, we include a single, two channel, 6 meter marine RCA cable to run from your head unit to the amplifier. Typically your tower speakers are treated as a single zone and since the JL Audio amps have selectable input switches, you can power all 4 channels from a 2 channel RCA. You don't need to fade from front to rear, but if you want to, you can always add an additional RCA, separately.

    Because mounting surfaces, tube diameters, and other variables are so different from boat to boat, we offer you the option to add mounting clamps, hardware, or OEM tower adapters. Also, don't forget to protect your investment by adding neoprene covers to cover your speakers while your boat is not in use.

    If you opt for the LED models, you will likely want to add an RGB LED controller if you don't already have one. We like the Stinger Marine RGB LED controller due to it's current rating and it has Bluetooth built-in so that you can change and control your speaker LEDs from your phone via an app. We also recommend Stinger 6 conductor, RGB LED speaker wire to easily power both your speakers and your lights with a single jacketed cable. The speaker wire has two 16 AWG conductors to power the speakers and 4 smaller conductors to connect to your speaker's RGB LEDs.
