It combines a woofer and tweeter in each speaker, providing a straightforward full-range replacement or upgrade for factory-installed speakers. The set is supplied without grilles for installations that retain the vehicle’s original speaker grilles or trim.\u003c\/p\u003e\u003cp\u003eRated at 60 watts RMS and 480 watts peak per speaker, the STAGE358F is suited to a compatible factory radio or an aftermarket amplifier. Its 4-ohm nominal impedance is designed to work with conventional car-audio speaker channels. With 89 dB sensitivity at 2.83V and a 55 Hz to 20 kHz frequency response, it is specified for balanced everyday music playback.\u003c\/p\u003e\u003cp\u003eThe 2-way coaxial layout places a PEI balanced-dome tweeter over the woofer, helping combine high-frequency detail and midrange output from one mounting location. This arrangement can be useful where the vehicle has a single factory speaker opening and no separate tweeter provision. The speakers are intended for listeners seeking an integrated replacement rather than a multi-piece component system.\u003c\/p\u003e\u003cp\u003eJBL uses its Plus One woofer cone architecture to increase usable cone area within the speaker frame. The laser-etched woofer cone is reinforced with 10% glass fiber, while the true 4-ohm design is intended to account for resistance elsewhere in the vehicle audio system. Together, these design choices support efficient output from compatible head units and amplifiers.\u003c\/p\u003e\u003cp\u003eThe Stage3 Gen2 design also incorporates post-consumer recycled plastic materials, PVC-free wiring, and packaging printed with soy-based inks. Two speakers, mounting hardware, foam gaskets, spade clips, logo badges, and a mini owner's manual are included. Confirm the vehicle's mounting diameter, depth, mounting-hole pattern, and factory connector requirements before installation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e5-1\/4-Inch Coaxial Design:\u003c\/strong\u003e Combines woofer and tweeter in each speaker.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e60W RMS Handling:\u003c\/strong\u003e Supports compatible factory radios or external amplifiers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlus One Woofer Cone:\u003c\/strong\u003e Adds cone area within the speaker frame.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePEI Balanced-Dome Tweeter:\u003c\/strong\u003e Handles high frequencies in the coaxial assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrue 4-Ohm Load:\u003c\/strong\u003e Matches common car-audio speaker-channel impedance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLaser-Etched Glass-Fiber Cone:\u003c\/strong\u003e Uses a 10% glass-fiber-reinforced woofer cone.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe STAGE358F uses a laser-etched woofer cone with 10% glass-fiber reinforcement and a PEI balanced-dome tweeter.

Verify physical fitment and ensure the connected head unit or amplifier is suitable for 4-ohm speakers before installation.\u003c\/p\u003e","brand":"JBL","offers":[{"title":"Default Title","offer_id":45632139526214,"sku":"JBLSPKS358F","price":76.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71prxnmw2CL.jpg?v=1784397135","url":"https:\/\/audiowatt.store\/products\/jbl-stage358f-5-25-2-way-coaxial-speakers","provider":"Audio Watt Store","version":"1.0","type":"link"}
