Some amplifiers employ car audio MOSFET transistors, more specifically the MOSFET car amplifiers. From the advantages alone, these components would have advanced features for automotive stereos. First, the input signal distortion is fairly minimized because of the greater impedance. Also, the capability of MOSFET car amplifiers to repeatedly turn on and off is quite beneficial in high frequency signal control. The development of sound quality underlies sharper detail and greater cleanness of the reproduced audio. Moreover, enhanced power efficiency accomplished through MOSFET technology results in far greater power delivered and lower energy consumption. These amplifiers are in great demand in the market for car audio systems that require increased power with lower energy use.
