A realistic simulation of the dynamic sounds of a full-sized vehicle are created on a moving R/C Scale Model. A mounting apparatus supports an audio exciter in a model vehicle without any modification to the exciter. A full range of volume of sound may be produced by the exciter without limiting the range of movement of the exciter as volume is increased or decreased. The apparatus may limit the mechanical excursion of the exciter to prevent physical damage to the exciter. The present invention also provides a method and apparatus for operating the audio exciter in a model vehicle.
