Bring serious low-frequency authority to your vehicle with the Alpine W-DB12V Dual 12" Bass Series Wedg-E Vented Subwoofer Enclosure. Loaded with two Alpine W12S4 12-inch subwoofers, this high-output enclosure is built for customers who want significantly more bass impact, deeper extension, and greater output than a single-subwoofer system.

With a combined power handling of 500 watts RMS and 1,500 watts peak, the W-DB12V delivers powerful, controlled bass from a rugged, precision-tuned vented enclosure. Its wedge-shaped design helps make efficient use of trunk or cargo space while directing serious low-frequency energy into the passenger compartment.

Dual 12-Inch Bass That Hits Harder

The Alpine W-DB12V combines two 12" Bass Series subwoofers in one high-output enclosure, giving you substantially more cone area and air movement than a single-subwoofer system. The result is deeper bass extension, stronger impact, and the kind of low-frequency performance you can both hear and feel.

For customers who want their music to have serious authority, the dual 12" configuration provides the output needed for bass-heavy music while maintaining the controlled sound Alpine Bass Series products are designed to deliver.

High-Output Wedg-E Design

The W-DB12V uses Alpine's Wedg-E enclosure design to combine high output with practical vehicle fitment. Its angled cabinet is designed to align naturally with the rear-seat angle found in many cars and SUVs, helping make efficient use of available cargo space.

The enclosure angle also helps reduce internal sound-wave interference while directing powerful bass toward the passenger compartment. Even with two 12" subwoofers, Alpine maintains a clean, integrated enclosure profile.

Precision-Tuned Vented Enclosure

The W-DB12V features a precision-tuned vented enclosure with a curved port designed to accommodate the increased airflow created by two 12" subwoofers. This allows the system to produce deeper low-frequency extension and greater output while remaining controlled under demanding listening conditions.

Optimized enclosure volume and port tuning help both W12S4 subwoofers work together efficiently, giving you powerful, consistent bass without requiring a custom-built enclosure.

Built for Serious Bass Performance

Each included Alpine W12S4 Bass Series subwoofer uses a lightweight polypropylene-mica cone engineered to remain rigid during high-excursion bass passages. This helps reduce unwanted cone flex and distortion while maintaining strong low-frequency output.

Durable poly-foam surrounds support the cone movement needed for powerful bass while maintaining stability. With two drivers operating together, the W-DB12V provides significantly more impact than Alpine's single 12" Bass Series enclosure.

Why You'll Love It

• Dual 12-inch output: Two large subwoofers move serious air for powerful bass you can feel.
• 500 watts RMS combined: Handles substantial amplifier power for strong everyday bass performance.
• Deep bass extension: Frequency response reaches down to 22 Hz.
• High-output vented design: Optimized for efficiency, low-frequency extension, and strong output.
• Ready to install: Both genuine Alpine W12S4 subwoofers are already mounted in the enclosure.
• Space-conscious wedge design: Fits naturally against many rear vehicle seatbacks.
• Premium construction: Durable MDF, black carpet, and Alpine embroidered branding.
• Optional protection: Compatible with Alpine KTE-12PG protective grilles.

500 Watts RMS of Dual 12" Alpine Bass

Each W12S4 subwoofer handles 250 watts RMS and 750 watts peak. With two subwoofers installed in the W-DB12V enclosure, total system power handling is 500 watts RMS and 1,500 watts peak.

This makes the W-DB12V an excellent step up for customers who want substantially more bass than a single 10" or 12" enclosure can provide without moving into a completely custom-built subwoofer system.

Technical Specifications

What's Included

• Alpine W-DB12V dual vented Wedg-E enclosure
• Two preinstalled Alpine W12S4 12" Bass Series subwoofers
• Dual speaker terminal connections
• Installation and product documentation

External Amplifier Required

The Alpine W-DB12V is a passive loaded subwoofer enclosure and does not include a built-in amplifier. A compatible mono amplifier, properly sized amplifier wiring kit, audio-signal connection, circuit protection, mounting hardware, and installation are required for operation.

Alpine recommends the S2-A60M mono amplifier with this enclosure. Final amplifier selection should consider the vehicle, factory or aftermarket radio, desired listening level, electrical system capability, and future system expansion.

Protect Your Subwoofers

The W-DB12V is compatible with Alpine KTE-12PG protective grilles, sold separately. Protective grilles are strongly recommended for SUVs, hatchbacks, cargo vehicles, and other installations where groceries, tools, sports equipment, luggage, or other cargo may come into contact with the subwoofer cones.

Professional Installation Recommended

A dual 12" subwoofer system requires properly sized power and ground wiring, correct circuit protection, a compatible amplifier, clean audio-signal integration, secure enclosure mounting, and careful amplifier tuning.

Incorrect gain, crossover, subsonic-filter, or bass-boost settings can introduce distortion and potentially damage the subwoofers. Professional installation helps ensure the W-DB12V performs safely and delivers the powerful bass it was designed to produce.
