It combines midrange and high-frequency drivers into each speaker, providing a straightforward way to refresh worn or limited factory audio. The 4-ohm design is intended to work with compatible factory or aftermarket car-audio systems.\u003c\/p\u003e\u003cp\u003eThis Street Series pair is suited to listeners upgrading smaller speaker positions in doors, dashboards, or rear decks. Its compact 4-inch format can be useful where a larger speaker cannot be installed. Vehicle-specific fitment should still be confirmed before purchase because mounting depth and cutout measurements are not provided.\u003c\/p\u003e\u003cp\u003eWith 80 watts RMS power handling per pair and 350 watts maximum power handling per pair, the SX402 is designed for systems that need a compact coaxial speaker upgrade. The 88 dB sensitivity supports operation with compatible head units and amplification. Match the speakers with an amplifier or receiver that is stable at 4 ohms and appropriately powered.\u003c\/p\u003e\u003cp\u003eA black injection-molded cone and rubber edge surround are used to support controlled cone movement. The specified 85 Hz to 22 kHz frequency response covers core midrange and high-frequency musical information for a small coaxial speaker. For deeper low bass, a dedicated subwoofer system may be considered where the vehicle and system design allow it.\u003c\/p\u003e\u003cp\u003eEach speaker uses a 1-inch aluminum voice coil and a 10-ounce magnet structure. Black steel baskets provide the mounting framework, while the included matching grilles use gold accents for a coordinated Street Series appearance. The package is intended as a two-speaker set for a single pair of vehicle speaker locations.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Inch Coaxial Design:\u003c\/strong\u003e Combines midrange and high-frequency reproduction in a compact speaker format.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Ohm Impedance:\u003c\/strong\u003e Works with compatible factory and aftermarket car-audio systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e80W RMS Per Pair:\u003c\/strong\u003e Provides stated continuous power handling for the included pair.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInjection-Molded Cones:\u003c\/strong\u003e Supports controlled cone movement for everyday music playback.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRubber Edge Surrounds:\u003c\/strong\u003e Helps support cone travel and midbass response.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Matching Grilles:\u003c\/strong\u003e Adds protection and a coordinated gold-accented appearance.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe SX402 uses black injection-molded cones, rubber edge surrounds, 1-inch aluminum voice coils, and 10-ounce magnet structures.
