Memphis PRX6903 6x9" 3-Way Coaxial Car Speakers

The Memphis PRX6903 is a pair of 6x9-inch, 3-way coaxial car speakers designed as a direct-size audio upgrade for compatible factory speaker locations. It combines woofer, midrange, and tweeter elements into each speaker to provide full-range playback from a single mounting position. This makes it a practical option for replacing worn or limited factory 6x9 speakers.

With 60 watts RMS and 120 watts peak power handling per speaker, the PRX6903 is suited to systems that need a moderate-power full-range speaker. Its 90 dB sensitivity supports efficient operation in a variety of car-audio installations. The 4-ohm design is compatible with common aftermarket speaker outputs.

The 3-way coaxial layout is intended to bring midrange and high-frequency detail into the same location as the 6x9 woofer. A PEI dome tweeter handles the upper frequencies, while the multi-direction pivot tweeter system allows the tweeter angle to be adjusted for the installation. This can help direct high-frequency sound toward the listening area where space permits.

Memphis uses a polyurethane surround and stealthy black-on-black M-Cone design for the PRX6903. The surround supports cone movement while contributing to the speaker's durable construction. Its integrated appearance suits installations where the speaker may be visible behind a grille or rear deck opening.

The PRX6903 fits into a system upgrade path for vehicles that use 6x9-inch speakers and have sufficient mounting clearance. It can be used as a replacement pair or matched with other compatible full-range speakers in a larger system. Grilles, speaker leads, mounting hardware, and a user manual are included for installation flexibility.

Design & Installation

The PRX6903 uses a polyurethane surround, PEI dome tweeter, and black-on-black M-Cone design. Each speaker has a 14-ounce magnet and a 3-inch mounting depth. The pair is supplied with two grilles for installations that require visible speaker protection.

Confirm that the vehicle accepts a 6x9-inch speaker and provides at least 3 inches of mounting depth before installation. Match the speakers to a compatible 4-ohm source or amplifier and avoid exceeding their 60-watt RMS rating per speaker. The package includes two 12-inch speaker leads, eight screws, eight speed clips, and a user manual; vehicle-specific mounting adapters or wiring interfaces may still be needed depending on the vehicle.
