Infinity leads the way for extreme summertime fun! The 6100M Wakeboard Sound System combines a marine amplifier and weather-resistant speakers, specifically designed for use with your boat's wakeboard tower. Now, when you're enjoying some wakeboarding, you and your buds can groove on some great-sounding tunes at the same time. The system even includes a "talkback" microphone for communicating with the boarder in the water.

The Wakeboard Sound System comes in two parts. First, two Wakeboard Tower Speaker Pods — each with two 6" polypropylene drivers and a 1" dome tweeter, housed in a tough polymer acoustic suspension enclosure. Each enclosure comes equipped with Infinity's rugged Multi-Mount, a specially-designed bracket that clamps the enclosure securely to your wakeboard tower.

To power the speakers, the sound system includes the 6100M marine amplifier. With two channels slamming out 125 watts of RMS power each, there'll be plenty of juice for blasting the tunes over the sound of wind, water, engine noise, and your whoops of joy! The amp has speaker- and line-level inputs, so you'll be able to hook the amp up to the boat's existing radio, tape, or CD player, or even a portable music player (with a line-level out).

Of course, don't limit yourself to wakeboarding. The rugged, weatherproof, and versatile design of the 6100M makes it a great way to provide the tunes for all of your maritime adventures.

Note: The 6100M includes speaker wire, but not an amplifier wiring kit. We recommend an 8-gauge amp wiring kit.

Crutchfield Customer Review (What's this?)

This is a well designed system. This is the perfect option for retrofitting a wake board tower for great sound. I recently completed the installation and was amazed at the sound. I can hardly wait for the weather to warm up to hit the lake and turn it loose.

Great package! Easy to install on Malibu Titan tower and sounds great.

PA control handles tower speaker music level and PA sound level... great way to 'dog' the downed boarder and to call out to passing people on boats and the shore...

We would do it again... 1st class system.

Crutchfield Customer Review (What's this?)

I was a little skeptical of purchasing a packaged unit such as the 6100m but I have installed it in my Air Nautique and have found it to be a great combination. The speakers and amp crank out plenty of sound to be hear by the boarders and the pa system is great to help my kids with their boarding. The volume controls on the pa mic are great as you can easily control the volume of the tower speakers without changing the other speakers in the boat.

Product Research


Overview: The Infinity 6100m Wakeboard Tower Sound System consists of 2 weather-resistant speaker pods, and a 2-channel amplifier. The speakers can be mounted to overhead wakeboard tower tubes, or surface mounted. A microphone is integrated into the amplifier to allow you to communicate with passengers or a water skier or wakeboarder you are towing.

Speakers: Each of the 6000m cast polymer speaker pods features two 6" polypropylene woofers (with rubber surrounds) and a 1" edge-driven C.M.M.D. dome tweeter. The black and silver speaker pods are resistant to UV rays, salt and water damage. The 6100m package includes two 42-1/2' lengths of speaker cable. Speaker pod dimensions: Width=17.5625", Height=12.1875", Depth=11". Note: C.M.M.D. is Ceramic Metal Matrix Diaphragm, Infinity's proprietary strong, lightweight speaker material.

Multi-Mount Bracket: The speaker pods feature a unique cast-aluminum "Multi-Mount" bracket that works with tower tubes of 1-1/2" to 2-1/2" in diameter or flat mounting surfaces. The top of the mounting bracket has four 1/4-20 threaded screw holes for mounting the speakers to a flat support panel. These same threaded screw holes can be used to attach lights or other accessories as well. Once the speakers are mounted, they can be swiveled up to 270 degrees in 45-degree increments.

Amplifier: The 6100m amplifier features both high-level and low-level inputs, line outputs, and an attached 12-1/2' microphone cable. The amplifier must be mounted in a remote location where it is protected from direct contact with water, whether from washing, big waves, or soggy riders. A Page EXT switch on the input end of the amplifier lets you choose whether or not you want the PA signal to pass through the Line Outputs to another amplifier and speakers.

Amplifier Specifications:

  • Power Output: 125 watts RMS x 2 at 4 ohms
  • Frequency Response: 10Hz - 40kHz
  • Signal-to-Noise Ratio: 91dB
  • Fuse Rating: 20 Amps x 2
  • Input Sensitivity:
    • Line Level: 250mV - 6V
    • Speaker Level: 6V - 16V
  • Minimum Impedance: 4 ohms stereo
  • Dimensions:
    • Length: 9.483"
    • Width: 8.06"
    • Height: 2.234"

Amplifier Wiring Recommendation: A standard 8-gauge amplifier wiring kit should be used to connect the amplifier to the boat's battery. If you are daisy-chaining additional amplifiers and speakers, you can connect the 6100m amplifier's Remote Out terminal to the Remote Input terminal of the other amplifier. The Remote Out terminal of the 6100m amp works with the power switch on the microphone.

Talkback Microphone: The talkback microphone, integrated into the amplifier, allows you to communicate with other passengers or to a water skier or wakeboarder being towed by your boat. The 12-1/2' microphone cable terminates into a waterproof connector plate which can be mounted to the operating console. The microphone features the following controls:

  • Push-to-Talk Button: located on the side of the microphone, lets you "key" the microphone before speaking
  • Power Switch: a 3-way slide switch on the front of the microphone has the following positions:
    • Off: turns off the 6100m system
    • Auto: allows the system to operate in conjunction with the Remote trigger from the boat's head unit
    • On: turns on the system, allowing the PA feature to be used without having to turn the connected head unit on
  • Level Controls:
    • Music Level: adjusts the volume of the music played through the 6100m system from the connected head unit
    • Paging/Microphone Level: adjusts the volume level of the paging system/microphone
