Upgrade the smallest factory speaker locations in your vehicle with 12 Volt Outlet's selection of 3.5" coaxial car speakers — compact full-range drivers that deliver dramatically improved sound quality over factory speakers in dash, door, and rear locations where only a 3.5" driver will fit.
The 3.5" coaxial is the go-to replacement for factory speaker locations found in dashboards, front door sail panels, and secondary speaker positions across a wide range of vehicles — particularly Japanese and European models where small-diameter dash and door speakers are common. Despite their compact size, quality 3.5" coaxials produce a full-range sound that far outperforms the thin, limited factory drivers they replace — with better sensitivity, cleaner midrange, and integrated tweeter reproduction that opens up the top end of the audio spectrum.
As a coaxial driver, the woofer and tweeter are combined into a single unit with a built-in passive crossover — check any required high-pass protection, wiring adapters and mounting hardware before installation. Confirm speaker impedance and power requirements against the factory head unit, aftermarket receiver or amplifier.
This collection includes products from Infinity, PowerBass, Rockford Fosgate, Hifonics, DC Audio, American Bass, JBL and AudioControl. Review the individual listing for exact features and compatibility.
