Dual 12-inch ported enclosure

This enclosure houses two 12-inch subwoofers in a ported design with side ports for enhanced bass output. It suits car audio enthusiasts who want deep low-frequency response without building a custom box. Builders needing a sealed alignment or a single-subwoofer layout should look elsewhere.

MDF construction with carpet finish

The front baffle uses 1-inch MDF while the remaining panels are 3/4-inch thick, providing a rigid structure that resists flex under high excursion. High-grade black carpet covers the exterior for a clean, professional appearance that matches most vehicle interiors.

Push terminals for secure wiring

High-performance push terminals simplify speaker wire connections and maintain a tight, reliable contact over time. No amplifier, wiring kit or grille is included, so installers must supply those separately to complete the system.

Questions about this item

How do I wire the subwoofers to the push terminals without reversing polarity?

Connect each subwoofer lead to the matching high performance push terminal on the MDF face, ensuring positive goes to positive and negative to negative before tightening the spring clips.

What part of the enclosure is most likely to wear out and need replacement first?

The high quality grade black carpet covering can fray or peel at the edges after repeated trunk loading and unloading.

At what point does the 33 by 18.5 by 14 inch internal volume limit output during long listening sessions?

The fixed internal air space restricts cone excursion once the dual 12 inch drivers demand more volume than the sealed chamber can supply, causing compression.
