8" Car Subwoofers

Get the perfect balance of size and output with 12 Volt Outlet's selection of 8" car subwoofers — the sweet spot for drivers who want more bass than a compact woofer can deliver without committing to a large enclosure or sacrificing cabin or trunk space.

An 8" subwoofer hits harder and reaches deeper than a 6.5" while still fitting comfortably in small sealed and ported enclosures, underseat boxes, and custom builds where space is limited. Fast, accurate, and punchy — 8" subs excel at tight, musical bass that complements any genre and sounds great at any volume level.

Shop 8" subwoofers in single and dual voice coil configurations with 2-ohm and 4-ohm impedance options for flexible wiring with any mono or multi-channel amplifier. Available in standard depth and shallow-mount designs to fit a wide range of enclosure types and vehicle applications — from compact underseat installs to custom ported builds tuned for maximum output.

We carry 8" car subwoofers from the most respected brands in the industry including Rockford Fosgate, B2 Audio, Soundqubed, Orion, Massive Audio, Audio Ace, DC Audio, Resilient Sounds, AudioControl, Jensen, Nemesis, Powerbass, JBL, Infinity, and more — brands that build subwoofers for real performance at every power level and price point.
