Constructed from rugged 5/8" premium MDF and reinforced with high-grade adhesives, this enclosure delivers vibration-resistant durability that stands up to the demands of the road. Dual binding post terminals ensure fast, secure, and hassle-free wiring, giving you reliable performance and pro-grade sound without the frustration.
