Hi Performance audio for your HD motorcycle without the loss of your saddle bags? For most this is a unheard combination that has resulted in the loss of all storage space and/or utility of your motorcycle. The ARC Audio MPAK (Motorcycle Performance Audio Kits) gives users a single package solution that lets riders upgrade their factory HD motorcycle audio system while keeping their precious cargo space.

With the amplifier installed on top of the factory location and using ARC Audio's new plug and play harness system ARC Audio MPAK kits integrate with the factory HD radio without cutting or splicing any of the factory wires which typically results in loss of the motorcycles electrical system warranty. In addition this installation allows you to keep all of your factory features and handle bar operation controls so you can continue to operate your system at its new level of performance without ever removing your hands from where they need to be.

All M.P.A.K. Kits include the KS125.2BX2 Mini amplifier equipped with BX2 bass technology. BX2 is a bass frequency extension technology that provides perceived bass frequency response below the low frequency cut off in an audio system.

BX2 uses the principle of the missing fundamental, which creates the sensation of low frequencies by generating a carefully calculated series of harmonics designed to simulate the auditory experience in the human ear caused by the missing fundamental pitch.

These harmonics extend the perceived frequency response up to 1.5 octaves below the speaker cutoff frequency (f3) without perceived distortion, increased peak power consumption or peak speaker excursion.
