Designed for standard 6.5-inch door openings, the speakers are a cost-conscious upgrade that fits most factory locations without complicated modifications. Sensitivity and impedance ratings make them compatible with a broad range of factory and aftermarket head units and amps.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these speakers improve everyday in-car listening?\u003c\/h3\u003e\n\u003cp\u003eThe CH6520B refines sound by combining a stiff poly cone with a compliant rubber surround and a tuned tweeter to reproduce vocals and instruments more clearly than many factory speakers.
