【Abstract】Automotive audio systems rely on power amplifiers to enhance audio signals and drive speakers to produce sufficiently loud and clear sound.During vehicle operation， multiple noise sources arise，compromising ride comfortndadverselyaffecting physicaland mentalwell-being.Active noisecancelationtechnology effectivelyaddrees noise challenges that physical insulation struggles toovercome，leadingto itsincreasing adoption.This paper explores how enhancing AMP functionalitycan optimize noise cancelltion performance in active noise reduction systems，aiming to providean effective technical pathway for improving the acoustic environment during driving.
