Skar Audio VS-12 D4 12-Inch Subwoofer | 1000W Max Power, Dual 4 Ohm, Shallow Mount

Compact Power with Deep Bass

The Skar Audio VS-12 D4 is a 12-inch dual 4-ohm subwoofer designed to deliver solid bass while fitting into tighter vehicle spaces. With a peak power rating of 1000 watts and a continuous RMS rating of 500 watts, this subwoofer aims to provide a muscular low end without requiring a large enclosure. The shallow-mount design, boasting a mounting depth of just 4.43 inches, makes it a versatile choice for trunks, SUVs, and compact cars where space is at a premium.

Key construction details support reliable performance. The cone uses a competition-grade pressed paper material paired with a high-roll rubber surround, which can help maintain durability and control during bass-heavy passages. The unit’s sensitivity is measured at 86.2 dB with a low-frequency resonance (Fs) of 37 Hz, indicating capability for strong, audible bass in typical vehicle enclosures.

Why this sub fits tight spaces

Shallow mounting depth opens up installation options that standard 12-inch woofers may not offer. Whether you’re tucking the driver under a seat, mounting it in a compact hatch, or configuring a small sealed or vented enclosure, the VS-12 D4 is built to adapt to constrained spaces while still delivering notable low-end presence.

What you might experience in real-world use

In everyday driving, you could notice a punchy, controlled bass response that enhances music with rock, hip-hop, and electronic genres. The dual 4-ohm design provides wiring flexibility for different amplifier setups, potentially helping you tailor the system to your vehicle’s acoustics. While results vary by enclosure choice and head-unit or amplifier pairing, the design emphasizes a clean, steady low end rather than bloated loudness.
