15" Subwoofers

Category Guide & Buying Information Fitment, power & selection tips

Shop 15-inch car audio subwoofers for high-output daily, street and competition builds. Compare RMS power handling, impedance, voice-coil configuration, mounting depth and enclosure specifications to choose a woofer that works with the amplifier and available vehicle space.

Plan Around Enclosure and Vehicle Space

  • Enclosure volume and tuning: Follow the specific woofer's sealed or ported airspace and tuning recommendations.
  • Mounting dimensions: Verify cutout diameter, basket clearance and mounting depth before choosing or building the enclosure.
  • Amplifier match: Use RMS ratings and the final wired impedance to match amplifier output to the subwoofer load.
  • System space: Confirm the full enclosure dimensions, port clearance and cargo or cabin space before ordering.

Support the Power Demand

A high-output 15-inch subwoofer system may place substantial demand on the amplifier and vehicle electrical system. Use correctly sized OFC wiring and fusing, and plan adequate alternator and battery support for the complete build. Crystal Audio Solutions can help match the woofer, enclosure, amplifier and electrical system.
