6.5" Coaxial Car Speakers

Upgrade the most popular speaker size in car audio with 12 Volt Outlet's selection of 6.5" coaxial car speakers — the single most common factory speaker replacement size on the market, fitting the front and rear door locations of more vehicles than any other diameter and delivering a full-range improvement that transforms how your system sounds.

The 6.5" coaxial is the benchmark of the car audio speaker world. It fits the factory door openings of an enormous range of vehicles — from compact imports to full-size trucks and SUVs — and produces a full, balanced sound that far outperforms anything the factory installed. The larger cone area compared to 5.25" drivers gives 6.5" coaxials better low-midrange output and bass extension, making them a noticeably fuller-sounding upgrade that brings body and warmth to your music that smaller speakers simply can't match.

Quality aftermarket 6.5" coaxials offer improved sensitivity, wider frequency response, and cleaner high-frequency reproduction through the integrated tweeter compared to factory speakers, delivering an immediate and dramatic improvement in overall system clarity and presence. Compatible with factory head units, aftermarket receivers, and external amplifiers — making them the ideal upgrade at any system level from a simple factory radio improvement to a fully amplified multi-channel build.

Installation is straightforward in most applications — the 6.5" coaxial drops into the factory opening, connects to the existing wiring, and is ready to play without modification in the majority of vehicles.

We carry 6.5" 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.
