Its 90Hz–10kHz published response range and 4-ohm impedance help define where it fits in a multi-driver system. Match the crossover, amplification and mounting to the driver rather than treating the nominal size as a guarantee of factory-location fit.\u003c\/p\u003e\u003ch2\u003eKey Features \u0026amp; Benefits\u003c\/h2\u003e\u003cul\u003e\u003cli\u003eNominal speaker size: 8 inches\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e8-inch midrange with integrated bullet compression tweeter\u003c\/li\u003e\n\u003cli\u003ePublished frequency response: 90Hz–10kHz\u003c\/li\u003e\n\u003cli\u003eImpedance: 4 ohms\u003c\/li\u003e\n\u003cli\u003eDie-cast aluminum basket, paper cone, cloth surround, 2-inch CCAW voice coil\u003c\/li\u003e\n\u003cli\u003eMounting depth: 3.03 inches \/ 77mm\u003c\/li\u003e\n\u003cli\u003eSold as a pair\u003c\/li\u003e\n\u003cli\u003ePublished sensitivity: 95.5dB; measurement reference not specified on page\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy Choose This Product?\u003c\/h2\u003e\u003cp\u003eThe SPM.804C belongs in a dedicated midrange section, not in place of a full-range speaker or subwoofer. Work through the physical installation and crossover arrangement as carefully as the power rating so the driver is used for the job it is designed to perform. For this model, the listed feature set includes Nominal speaker size: 8 inches. Check how that feature fits your intended system rather than substituting specifications from a similar model.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Compatibility Notes\u003c\/h2\u003e\u003cp\u003eConfirm mounting depth, cutout size and clearance before installation. Use suitable crossover filtering and match amplifier output to the manufacturer’s continuous-power guidance.

Nominal size is a starting point; cutout and mounting depth must be checked separately.\u003c\/p\u003e\u003ch3\u003eWhat frequency range is specified for the SPM.804C?\u003c\/h3\u003e\u003cp\u003ePublished frequency response: 90Hz–10kHz. Use a crossover appropriate to the driver and application; a published response range does not guarantee equal output across the entire range.\u003c\/p\u003e\u003ch3\u003eWhat impedance is specified for the SPM.804C?\u003c\/h3\u003e\u003cp\u003eImpedance: 4 ohms. Match the total connected load to the amplifier, accounting for all drivers on the channel.\u003c\/p\u003e\u003ch3\u003eWhat construction details are listed for the SPM.804C?\u003c\/h3\u003e\u003cp\u003eDie-cast aluminum basket, paper cone, cloth surround, 2-inch CCAW voice coil. These are model-specific construction details; they do not establish vehicle fit or replace the need for correct mounting and filtering.\u003c\/p\u003e\u003ch3\u003eIs the SPM.804C a direct-fit replacement for my vehicle?\u003c\/h3\u003e\u003cp\u003eA shared nominal speaker size is not a vehicle-fit guarantee. Compare cutout, depth, mounting pattern and grille clearance; vehicle-specific mounting brackets or wiring adapters may be required.\u003c\/p\u003e\u003ch2\u003eExplore More\u003c\/h2\u003e\u003cp\u003eCompare \u003ca href=\"\/collections\/car-speakers\"\u003eCar Speakers\u003c\/a\u003e or read our \u003ca href=\"\/pages\/soundstream\"\u003eSoundstream brand guide\u003c\/a\u003e.
