5.25" Coaxial Car Speakers

Upgrade one of the most common factory speaker sizes in the industry with 12 Volt Outlet's selection of 5.25" coaxial car speakers — full-range drop-in replacements that fit front and rear door locations across hundreds of vehicle makes and models, delivering a clear, meaningful improvement over factory sound quality right out of the box.

The 5.25" coaxial is a staple of car audio for good reason — it fits a massive range of factory door and dash speaker openings and produces a well-balanced, full-range sound that punches above its size. Quality aftermarket 5.25" coaxials deliver noticeably better sensitivity, wider frequency response, and cleaner integrated tweeter reproduction than the factory speakers they replace, making them one of the highest-impact, lowest-effort speaker upgrades you can make to any vehicle.

The coaxial design combines the woofer and tweeter in a single unit with a built-in passive crossover — check any required high-pass protection, mounting dimensions and wiring adapters. Match speaker impedance and power requirements to the connected head unit or amplifier.

Compare 5.25" coaxial car speakers from American Bass, Rockford Fosgate, DS18, Soundstream, Hifonics and JBL. Check each listing for exact specifications and installation requirements.
