The Polk Audio DB571 5-by-7-Inch Coaxial Speakers can be used with a factory head unit without the need for an amplifier. These speakers are designed to work well with the power output of a standard car stereo system. While they can handle higher power levels, they will still provide good sound quality and volume when connected directly to your car's head unit. So you can simply plug and play these speakers in your car without the need for an additional amplifier.
