Skar Audio EVL-1X65D4-V-LP 6.5” Low-Profile Slot-Ported Sub Enclosure | 400W Max

Compact, high-impact bass for tight spaces

The Skar Audio EVL-1X65D4-V-LP is a compact loaded subwoofer enclosure designed for audiophiles who want loud, responsive bass without sacrificing trunk or rear-seat space. With a shallow 5.25" depth, it fits behind the seats in many pickup trucks and into the trunks of smaller cars, delivering a surprising amount of low-end presence from a single, purpose-built cabinet.

Despite its small footprint, this 6.5-inch system relies on a slot-port design to yield bass with authority. The enclosure houses one EVL-65 D4 subwoofer (200W RMS, 400W max) wired to a 2-ohm final impedance, giving you a direct path to honest, punchy low notes when you crank up the volume. The result is bass that feels solid and controlled, not boomy, and it stays responsive at higher listening levels.

Quality construction and finish

Built to endure, the enclosure uses 5/8" MDF for stiffness and features internal bracing to maximize usable box volume while maintaining structural integrity. A premium black carpet exterior provides an attractive look, and a protective grille keeps the driver covered during daily driving or adventures. The system is tuned for solid, musical bass at around 56 Hz, balancing deep lows with musical clarity.
