Specifications

Important Programing Note:

 The amplifier gain & frequency response adjustments have been pre-set at our factory for this specific 

Harley Davidson audio system application, using speakers with an impedance of 2-ohms, to provide maximum performance at highway 

speeds. Should speaker impedance load change, alternate adjustments can be made by removing the small sticker that is placed over 

the amplifier’s input gain control screw.
