It is designed for custom enclosures and aftermarket systems that need bass reinforcement without giving up much installation space. Its 150-watt RMS rating makes it suitable for use with a properly matched external amplifier.\u003c\/p\u003e\u003cp\u003eThis Power Reference Series model is a practical choice for vehicles with limited cargo room, compact custom installs, or multi-subwoofer systems. Its selectable impedance design lets the installer configure the subwoofer for either a 2-ohm or 4-ohm load using the included jumper wires. That flexibility can simplify amplifier matching and future system changes.\u003c\/p\u003e\u003cp\u003eThe PRX624 is intended for bass frequencies, with a stated frequency response of 50 to 150 Hz. A 6.5-inch subwoofer will not replace the air-moving capability of a larger woofer, but it can provide focused low-end reinforcement in an appropriately designed enclosure. Sealed and vented enclosure recommendations are available for single- and dual-subwoofer applications.\u003c\/p\u003e\u003cp\u003eMemphis uses a black polypropylene cone, double-stitched butyl rubber surround, reinforced spider shoulder, and woven tinsel leads in the PRX624. The subwoofer also incorporates DVVC Direct Voice Coil Cooling and a high-temperature TIL voice coil former. These construction details support stable operation at its rated power level.\u003c\/p\u003e\u003cp\u003eThe PRX624 works well as part of a compact bass upgrade paired with an amplifier that is stable at the selected final impedance. It can be used in a single-sub enclosure for a small-footprint system or in pairs where additional output is desired. Proper enclosure volume, secure mounting, crossover setup, and amplifier gain adjustment are important to its performance and reliability.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable Impedance:\u003c\/strong\u003e Included jumpers configure the subwoofer for 2- or 4-ohm operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e150W RMS Handling:\u003c\/strong\u003e Supports an amplifier delivering up to 150 watts RMS.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact 6.5-Inch Format:\u003c\/strong\u003e Helps fit dedicated bass into space-conscious vehicle installations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePolypropylene Cone:\u003c\/strong\u003e Provides a rigid cone surface for low-frequency reproduction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble-Stitched Butyl Surround:\u003c\/strong\u003e Supports cone movement while adding long-term durability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDVVC Cooling:\u003c\/strong\u003e Direct Voice Coil Cooling helps manage voice-coil heat under load.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe PRX624 uses a stamped steel frame, black polypropylene cone, double-stitched butyl rubber surround, reinforced spider shoulder, woven tinsel leads, and a high-temperature TIL voice coil former. Its 41-ounce magnet structure and 1.5-inch voice coil are paired with a compact 3-inch mounting depth. A removable rubber trim ring\/gasket is fitted at the mounting surface.\u003c\/p\u003e\u003cp\u003eAllow for a 5.67-inch cutout and at least 3 inches of mounting depth, while also checking clearance behind the mounting location. Select the 2-ohm or 4-ohm configuration with the supplied jumper wires before connecting the amplifier, and verify that the amplifier supports that load. Memphis specifies a 0.35-cubic-foot sealed enclosure or a 0.5-cubic-foot vented enclosure for one subwoofer; a vented design uses a 2-inch-diameter, 8.75-inch-long port tuned to 47 Hz.\u003c\/p\u003e","brand":"Memphis","offers":[{"title":"Default Title","offer_id":45633197113414,"sku":"PRX624","price":69.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71iMjB6s9mL.jpg?v=1784413975","url":"https:\/\/audiowatt.store\/products\/memphis-audio-prx624-6-5-selectable-impedance-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
