PST12 - Hidden 12” Passive Car Audio Spare Tire Subwoofer System

The PST12 is a 12-inch passive subwoofer built specifically to fit inside a vehicle's spare tire well, keeping your cargo space intact while still delivering up to 350 watts RMS. Its die-cast aluminum enclosure doubles as both a protective housing and a space-efficient mounting solution. This is a purpose-built unit for drivers who want real bass output without sacrificing trunk real estate.

• Spare tire fitment: Designed to drop directly into the spare tire well for a clean, hidden install.
• 350W RMS power handling: Fiberglass cone and rubber surround hold up under sustained high-volume use.
• Dual 4-ohm voice coils: Wiring flexibility to run the sub at 2 ohms or 8 ohms depending on your amplifier setup.
• Die-cast aluminum enclosure: Protects the driver from cargo impacts while keeping the overall profile compact at 12.95" x 4.72".
• Frequency response of 52 Hz – 150 Hz: Covers the core bass range without requiring active EQ or a separate bass boost circuit.
• Includes installation hardware: Ready to mount out of the box.
