The enclosure fits under the rear seat, preserving cargo space while adding strong low-end extension. With the same dual 800W subs (VD-12 D4) setup as other Skar enclosures, it offers a balanced mix of punchy bass and reliability for daily commutes or weekend trips.

Buying Guide
- Vehicle fit and space: Measure under-seat clearance and ensure the enclosure or slim sub fits without obstructing seat slides or seat belts. Under-seat designs optimize space but may reduce mounting options in larger cabs.
- Power handling and calibration: Consider peak vs RMS power ratings. Enclosures with built-in amplifiers simplify installation but may limit future upgrade paths. A separate amp may offer more tuning flexibility for expert users.
- Sound signature: Ported enclosures generally emphasize deeper bass extension, while sealed enclosures tend to offer tighter, more controlled bass. Subwoofer configurations (dual 12″ vs single 10″) affect overall output and space use.
- Electrical demand and head unit compatibility: Ensure your vehicle’s electrical system supports the added bass load. Check for wiring requirements and remote turn-on compatibility with your head unit.
- Build quality and heat management: Aluminum shells and quality MDF contribute to durability and heat dissipation, especially in under-seat placements where airflow is limited.
- Installation considerations: Some products include mounting hardware and pre-wired configurations, while others require custom fabrication. Factor in installation time and potential professional help.
- Sound tuning controls: Built-in crossovers, gain, and bass boost controls help tailor bass output to your music genres without overloading speakers or rattling interior panels.
- Price-to-performance balance: Compare total system capabilities, including enclosure type, driver configuration, and built-in amplification, to determine value for your truck’s needs.
