4" Coaxial Car Speakers

Replace your factory 4" speakers and hear a real difference with 12 Volt Outlet's selection of 4" coaxial car speakers — full-range drop-in replacements for the compact speaker locations found in doors, dashes, and rear positions across hundreds of vehicle makes and models.

The 4" coaxial is one of the most common factory speaker sizes in the automotive world, appearing in front and rear door locations across a wide range of domestic and import vehicles. Factory 4" speakers are typically underpowered, limited-range drivers that sacrifice sound quality for cost — replacing them with a quality aftermarket 4" coaxial immediately opens up the frequency response, improves sensitivity, and delivers a cleaner, more detailed sound that the stock system could never produce.

As a coaxial design, the woofer and integrated tweeter work together through a built-in passive crossover to deliver full-range sound from a single driver. Installation is straightforward — the 4" coaxial fits directly into the factory opening in most applications, connects to the existing wiring, and works with factory head units and aftermarket receivers without modification. No crossovers to mount, no extra wiring to run, no complexity.

We carry 4" coaxial car speakers from the most respected brands in the industry including Rockford Fosgate, AudioControl, Massive Audio, American Bass, Deaf Bonce, DC Audio, Powerbass, Hifonics, Jensen, JVC, Infinity, JBL, and more — brands that deliver real sound quality improvement in every size they build.
