Abstract
An active noise attenuation system includes a speaker housing for a speaker assembly that attenuates noise generated by an air induction system for a vehicle engine. The speaker housing is a generic housing formed from plastic that can be utilized with many different vehicle types. An air cleaner housing is positioned between the speaker housing and the engine for filtering out contaminants from the air before the air is drawn into the engine. Brackets are joined to the air cleaner and speaker housings for mounting the housings to a vehicle structure.
