8" Car Subwoofers

8-inch car subwoofers give you a compact way to add low-end output to a car audio system. At 12 Volt Outlet, we carry options for different enclosure plans and amplifier setups, from shallow-mount models to high-power drivers. Compare RMS handling, voice-coil impedance, and mounting requirements to find a sub that suits your build.

High-Power 8-Inch Competition Subwoofers

For a high-output build, check the power rating and voice-coil options before choosing an amplifier. The Sundown Audio X-Series v.4 handles 1,250W RMS and offers dual 2- or 4-ohm coils, with sealed and ported enclosure guidance. The SoundQubed HDX3.2 handles 1,500W RMS and is available with dual 1-ohm or 2-ohm coils.

Shallow-Mount 8-Inch Subwoofers

Working with limited mounting space? The Audiopipe TS-FA800 has a 65 mm mounting depth and dual 4-ohm voice coils. Check the available space and wiring plan in your vehicle before selecting a shallow subwoofer.

How to Choose an 8-Inch Subwoofer

Start with the space available, then match the subwoofer’s RMS rating and coil configuration to your amplifier and enclosure. For a lower-power option, the Audiopipe TS-CAR8 features a polypropylene cone, edge extension technology, 150W RMS, and 4-ohm impedance. Review each model’s listed specifications as you compare options.

We also carry Car Subwoofers in more sizes, including 10-inch car subwoofers and Shallow Car Subwoofers for space-conscious installs.
