Designed for 2019–2025 Dodge Ram Crew Cab trucks, this sealed dual subwoofer enclosure delivers a fitment-focused bass upgrade with a clean install. It arrives preloaded with two Alpine R2-W12D4 12-inch subwoofers, reducing installation time and removing the guesswork of matching box volume and speaker placement. The Crew Cab-specific layout helps the enclosure sit properly for a secure, organized setup. It’s a practical solution for drivers who want stronger bass without a custom fabrication project.
The sealed design emphasizes controlled, accurate low-frequency response that stays musical across different genres. Compared to many vented enclosures, sealed performance is often preferred for tighter punch and smoother integration with factory or aftermarket door speakers. With 750W RMS at 4 ohms, this bundle supports strong output while maintaining bass definition when paired with a compatible amplifier. Proper amp tuning and secure mounting help keep response consistent over time.
Constructed from rigid MDF with internal reinforcement, the enclosure is built to handle vibration and daily use in truck environments. The carpeted exterior supports a factory-style appearance and helps protect the enclosure surface during normal use. Preloaded subwoofers are mounted correctly for the enclosure’s internal volume to support predictable performance. This bundle is ideal for Ram Crew Cab owners who want sealed-box accuracy with high power capability.
