Factory radios on 2014 and later Harley-Davidson audio systems have an output signal that has been tailored by the manufacturer to have a custom frequency response curve which matches the acoustic response of their own loudspeakers. When installing aftermarket loudspeakers and amplifiers the audio system will have excessive gain and likely sound distorted. In order to use different aftermarket loudspeakers and amplifiers with these types of radio head units they need to reprocess the signal to flatten its response. This is done by first measuring the O.E.M. response and then constructing an equalizer to reverse the manufacturer's signal and generate a flat response output. The Cycle Sounds engineering team did just that when they developed the DSP Line-Level Shifter "Magic Box" interface. This module simply adapts the head unit's frequency response and speaker level signal to match the input level amplitude, impedance and frequency response for aftermarket audio products; all without the need for a dealership to "flash" your radio upon upgrading.
The best part about Cycle Sounds' DSP Line-Level Shifter is that everything is plug-and-play using the factory Harley-Davidson connectors; no cutting or splicing wires.
You can even use the (Magic Box) Line-Level Shifter to simply add an upgraded amplifier to your factory (5-1/4") speakers, boosting volume and clarity while providing an easy upgrade path for other aftermarket audio equipment.
The Magic Box is compatible with Cycle Sounds' Aftermarket Speaker / Amplifier Connection Kit for 2014 and later Harley-Davidson (sold separately) that includes the O.E.M. connectors for the speaker pods so you don't have to cut or splice a single wire!
All Cycle Sounds products carry a one year manufacturer's warranty and are guaranteed to be free from defects in craftsmanship.
Note: Rockford Fosgate T-Series amplifiers with C.L.E.A.N. input / output clip detection will need specific adjustments made to the amplifier to optimize the sound.
