15" Car Subwoofers

15-inch car subwoofers give you a large driver to build around, and we can help you compare power handling, voice-coil impedance and enclosure needs. Check the subwoofer’s fit and wiring options against your vehicle and amplifier before choosing.

Choosing a 15-inch subwoofer for your system

Start with RMS power handling and the final impedance your amplifier supports. The Audiopipe TXX-BDX-15D2 handles 2,000W RMS and has dual 2-ohm voice coils, with series or parallel wiring options. The Sundown Audio U-Series v.2 handles 2,000W RMS and offers D2 or D4 voice coils. Match the wiring plan to your amplifier’s supported load.

15-inch subwoofers for ported enclosures

Enclosure recommendations vary by model, so use the product’s guidance when planning your box. The Sundown Audio Z-Series ZV6 is rated at 3,250W RMS, offers D1 or D2 coils and has 4 cu ft ported enclosure guidance. Confirm your available space and mounting requirements before building or choosing an enclosure.

Plan the complete bass setup

A subwoofer is one part of the system. We recommend checking amplifier power and impedance compatibility, wiring needs and enclosure fit together rather than choosing by power rating alone.
