Helix M FOUR DSP 4-Channel Amp with Integrated 10-Channel DSP

$999.99

Intelligence Mixed with Incredible Power from Helix

The Brand New Helix M FOUR DSP is a powerful 4-channel amplifier with a fully-integrated digital sound processor manufactured in Germany that brings a continuous output of 135 Watts per channel, both at 4 Ohms and 2 Ohms. This game-changing control center is cool, compact, extremely practical, and up for any challenge in your Harley system.

Perfect for integration with factory Harley radios, the M Four amplifier/DSP has a number of features that make it totally different than anything else ever made.

 

How it Works

4 channels of internal power and 6 more channels of RCA out for additional amplifiers. All 10 channels have a full range of DSP function

Helix M Four DSP Amplifier EQ Screen-Bike

This amplifier has no knobs or switches on it. It uses a very slick PC interface to set everything up. The best part is that the software allows you to see both what the radio signal looks like as well as all adjustments that you make with the processor. For serious systems, this is the ultimate amplifier and tuning tool. 

Dynamic Bass Enhancement

The “Dynamic Bass Enhancement” ingeniously combines maximum deep bass and highest sound pressure – regardless of the music style or the tone controls in the head unit. Depending on the input signal, the “Dynamic Bass Enhancement” gains the lower frequency range and varies the cut-off frequency of the subsonic filter. The result is a significantly more powerful and deeper bass response at low and medium volume levels without the risk of overloading the subwoofer neither mechanically nor electrically at high volume levels. It is simply fascinating what bass performance is suddenly possible.

Features:

  • StageXpander makes the entire system sound bigger and bolder
  • Dynamic Bass Enhancement maximizes deep bass
  • ClarityXpander feature adds additional harmonics in the upper-frequency range
  • Built-in input RTA and input EQ that can compensate for any radio flash. No need to flash your bike for a perfect signal.
  • Built-in 10 channel EQ, crossover, phase control
  • Built-in signal meter and anti clipping feature saves speakers at insane volume levels 
  • 135 Watts RMS output power per channel
  • Extremely efficient low-heat dissipation
  • Bridgeable amplifier channels for driving powerful speakers
  • DSP-board manufactured in Germany

Fitment:

Fits '14+ Street Glide, Electra Glide, Ultra models in the fairing on top of the radio. '15+ Road Glide requires slight modification to headlight bracket and headlight plastic mounting tabs. Will not fit in the fairing of '13 and down Road Glide or Street Glide. 

Works with all radio flashes. 

 Helix M Four DSP Amplifier Harley Radio Connections

Factory Harley Radio Interface for Front Signal Included

No need to buy a separate radio connection harness. Plug-and-play connections are included with this amplifier. There is also no need for an external radio load compensation network either. The Helix M Four DSP amplifier has an advanced radio load compensation circuit built-in. Helix amplifiers simply do not require the complex and bulky signal interfaces that all other amplifiers and DSP units require. This makes connections much simpler and much cleaner.

Factory Harley Accessory Power Interface Included

No need to cut into the factory radio harness to get accessory turn-on power. A plug-and-play connection and cable is included.
