The Memphis PRX603 bundle combines a pair of 6.5-inch, 3-way car speakers with a pair of compact Rockville RPB3-BLACK Bluetooth speakers. It is suited to drivers replacing worn factory door or rear-deck speakers while adding a separate portable listening option. The car speakers are designed to fit many factory-sized 6.5-inch locations with a 2.25-inch mounting depth.
The PRX603 speakers use a 3-way coaxial layout to place woofer, midrange, and tweeter elements in each speaker assembly. With 50 watts RMS and 100 watts peak power handling, they are appropriate for compatible factory radios or aftermarket amplification. Their 88 dB sensitivity and 4-ohm impedance support conventional car-audio system integration.
A graphite-reinforced polypropylene cone and butyl rubber surround form the main woofer assembly. The design is intended to provide durable operation in a vehicle environment while maintaining controlled cone movement. A PEI cone midrange and PEI dome tweeter handle upper-frequency reproduction.
The PRX603 includes a multi-direction pivot tweeter system to help direct high frequencies toward the listening area. Its integrated 6 dB tweeter crossover is built into the speaker design, simplifying installation compared with a separate component speaker system. Grilles are included for custom or exposed mounting applications.
The included Rockville RPB3-BLACK pair is separate from the vehicle speaker system and provides portable Bluetooth playback. The two mini speakers can link wirelessly in True Wireless Stereo mode, and each has a 40 mm driver, built-in SD card slot, and microphone for hands-free calls. They are useful at home, at work, or away from the vehicle when a compact portable speaker pair is preferred.
Key Features
- 6.5-Inch 3-Way Coaxials: Replaces many factory-size speaker locations with integrated woofer, midrange, and tweeter drivers.
- 50W RMS Power Handling: Supports matching with compatible factory radios or aftermarket amplifiers.
- Pivoting PEI Dome Tweeters: Helps aim high-frequency output toward the listening position.
- Graphite-Reinforced Polypropylene Cones: Provides a rigid woofer cone structure for everyday vehicle use.
- Integrated 6 dB Tweeter Crossover: Simplifies the coaxial speaker design without separate external crossover boxes.
- Portable Bluetooth Speaker Pair: Includes two Rockville RPB3 speakers with Bluetooth 5.0 and TWS linking.
Design & Installation
The PRX603 speakers use graphite-reinforced polypropylene woofer cones, butyl rubber surrounds, PEI midrange cones, and PEI dome tweeters. Their black speaker design includes grilles, while the Rockville RPB3-BLACK portable speakers use aluminum housings and weigh 95 g each. The portable speakers are finished in black.
Confirm vehicle-specific fitment before installation, including the 6.5-inch speaker opening, 4.843-inch cutout diameter, available mounting depth, and clearance for the 0.772-inch mounting height. Connect the PRX603 pair to a compatible 4-ohm car-audio channel and match amplifier power responsibly to the 50-watt RMS rating. The RPB3 portable speakers charge from a DC 5V/1A source and can be paired by Bluetooth or linked together for TWS playback.
