The time has come to take a stand against disappointing sound, and Memphis Audio's Power Reference Series PRX4 4" 2-way car speakers are your allies in the quest to bring some fun back to your drive. These speakers handle up to 20 watts RMS, but they'll deliver excellent performance, whether you're driving them with a factory radio or an aftermarket amp.

The tweeter's multi-directional pivot system lets you angle high frequencies toward your ears.
Pivoting tweeter
A sensitive yet tough polypropylene cone bolsters the lows while a PEI dome tweeter handles detailed delivery of the high range. Memphis Audio even goes a step beyond by equipping the tweeter with a multi-directional pivot system so that you can create the best soundstage for your car.
