The car subwoofer speaker voice coils are available with either dual 2 ohm, or dual 4 ohm impedance voice coils for multiple wiring configurations.

Beat the Heat

Heat kills coils! Like any speaker, subwoofer voice coils collect heat, especially at higher power levels. The vented electroplated back plate lets heat escape smoothly with less turbulence in the coil gap. Designed to withstand temperatures over 350 degrees (F), the high-quality copper coil wire guarantees reliable long-term performance.

Dual Voice Coil

The HDS206-D4’s 2″ diameter, four-layer speaker subwoofer for car voice coils withstand high temperatures by incorporating high-quality wire and high-temperature adhesives. Having two coils allows for series or parallel wiring. With either 2 or 4 ohm impedance options, you can make your car speaker’s subwoofer 6.5 inch happy by wiring for the correct RMS power from your amp.

Built for Bass

With 60 oz of magnet, this is a small subwoofer for car motor! A cast aluminum frame supports a three-piece suspension and non-pressed fiber reinforced cone for maximum efficiency and lower tuning in a ported enclosure. The conical back plate allows for longer voice coil travel while the wide, tall surround allows for a long, controlled excursion.
