It is intended for vehicle owners replacing OEM door speakers where a conventional full-depth driver may require adapters or panel modification. Each woofer uses a 4-ohm design and is rated for 70 watts continuous power handling.\u003c\/p\u003e\u003cp\u003eThe C165F is well suited to OEM-style upgrades that prioritize fitment while improving midbass and lower-midrange output. Its published frequency response is 65 Hz to 4.5 kHz, making it a dedicated woofer rather than a full-range coaxial speaker. It can be used in a properly planned component system or as a replacement woofer where compatible factory components are retained.\u003c\/p\u003e\u003cp\u003eA shallow basket reduces the required mounting depth to 43.5 mm (1.71 inches), helping the C165F fit behind door panels and other constrained factory mounting locations. The 141 mm (5.55-inch) cutout requirement should still be checked against the vehicle's factory opening and adapter requirements. Its 165 mm (6.5-inch) outer diameter suits many common aftermarket speaker positions.\u003c\/p\u003e\u003cp\u003eThe woofer uses Hertz SPP-M semi-pressed paper reinforced with mica, a cone material selected for low mass and stiffness. A high-density-flux ferrite motor with low-carbon polar plates supports the driver structure, while the 25 mm pure-copper voice coil is wound on an aluminum former. These design elements support controlled operation in a compact, shallow driver format.\u003c\/p\u003e\u003cp\u003eWith 93 dB sensitivity and a 4-ohm nominal impedance, the C165F can be considered for factory-radio upgrades or amplified systems when power and impedance compatibility are verified. Its 70-watt continuous rating gives installers a clear target when selecting amplification. For wider frequency coverage in a front-stage system, pair the woofers with compatible tweeters and suitable crossover filtering.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShallow-Mount Profile:\u003c\/strong\u003e 43.5 mm mounting depth helps fit restricted factory locations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e6.5-Inch Woofer:\u003c\/strong\u003e Fits many common door and factory speaker applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSPP-M Cone:\u003c\/strong\u003e Mica-reinforced semi-pressed paper balances stiffness and low mass.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFerrite Motor:\u003c\/strong\u003e High-density-flux ferrite supports the compact driver design.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e25 mm Voice Coil:\u003c\/strong\u003e Pure copper coil uses an aluminum former.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Ohm Load:\u003c\/strong\u003e Matches many conventional car audio amplifier channels.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe C165F combines a super-slim basket with a semi-pressed paper and mica cone, high-density-flux ferrite magnet, low-carbon polar plates, and a copper voice coil on an aluminum former. Each speaker weighs 0.72 kg (1.59 lb) and uses a 90 x 32 x 10 mm ferrite magnet. The driver has a 165 mm overall diameter and a 50.6 mm overall depth.\u003c\/p\u003e\u003cp\u003eConfirm the vehicle's available depth, 141 mm cutout diameter, mounting surface, and clearance behind the door panel before installation. Observe speaker polarity and use secure mounting hardware appropriate for the vehicle or adapter ring. For amplified use, select a stable channel compatible with a 4-ohm speaker and set gain responsibly around the 70-watt continuous rating per woofer.\u003c\/p\u003e","brand":"Hertz","offers":[{"title":"Default Title","offer_id":45631717212230,"sku":"C165F","price":199.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71EUg0pI7FL.jpg?v=1784378190","url":"https:\/\/audiowatt.store\/products\/hertz-c165f-6-5-shallow-mount-woofers","provider":"Audio Watt Store","version":"1.0","type":"link"}
