The 12″ Double SPL Carpet Car Box

 is a heavy-duty subwoofer enclosure designed for high-output car audio systems and bulk supply. Built to house two 12-inch subwoofers, it delivers increased bass headroom and cleaner low-frequency performance. The rigid MDF construction minimizes resonance, while the acoustic carpet finish protects the enclosure and blends with vehicle interiors. Pre-cut 12″ apertures allow for fast, professional installation. Ideal for car audio installers, retailers, and resellers, this enclosure is available in Black, Blue, and Red.
