Subwoofer Enclosures

A properly matched subwoofer enclosure is critical to getting the best performance from your sub. Whether you're chasing tight, punchy bass or deep, resonant lows, the right box helps your subwoofer sound cleaner, louder, and more accurate. At GP Car Audio, we offer a wide range of subwoofer enclosures to match your goals, space, and setup. Each one is designed to maximize output and protect your investment.

Why a Quality Subwoofer Enclosure Matters

Even the most powerful subwoofer can fall short if it's placed in a poorly designed box. The enclosure shapes how your sub performs by controlling airflow, resonance, and speaker excursion. Here's why a quality enclosure is essential:

  • Improved Bass Response. A matched enclosure helps your sub hit harder and play deeper with better accuracy across low frequencies.
  • Reduced Distortion. Proper internal volume and airflow minimize unwanted vibrations and eliminate muddy bass.
  • Increased Efficiency. The right box allows your subwoofer to work smarter, not harder, often resulting in louder sound with less power.
  • Longer Subwoofer Life. A durable enclosure provides protection from physical damage and helps prevent over-excursion and cone fatigue.

Types of Subwoofer Enclosures

Choosing the right type of box depends on the sound you’re after, your vehicle’s space, and your subwoofer’s specifications. Here are the most common types:

Sealed Enclosures

Best for: Tight, accurate bass.
Sealed boxes are compact and deliver clean, precise bass response. They're perfect for those who want musical accuracy over extreme volume.

Ported Enclosures

Best for: Louder output and deeper lows.
Ported boxes use a tuned vent to amplify low frequencies, making them ideal for bass-heavy genres like hip-hop, EDM, and trap.

Bandpass Enclosures

Best for: Maximum SPL and boom.
Bandpass boxes are designed for high output within a narrow frequency range. They’re great for loud, show-stopping bass but require precise tuning.

Custom and Vehicle-Specific Enclosures

Best for: Perfect fit and tailored sound.
Custom-built enclosures are made to fit your vehicle and subwoofer exactly, offering superior sound quality and a clean installation.

Common Sub Enclosure Questions

What’s the difference between a pre-fab box and a custom-built enclosure?

Pre-fab boxes, like those from Tru-Spec, are ready-made and designed for general use, while custom glue-it-and-screw-it enclosures are built to your exact specs for optimal performance and fit.

How do I know which enclosure is right for my subwoofer?

Check your sub’s size, mounting depth, and airspace requirements. Our team can help match you with the perfect box for sealed, ported, or custom setups.

Do your enclosures come with terminals and wiring?

Tru Spec prefab boxes do not include a terminal, but our Glue It & Screw custom enclosures do. Wires need to be purchased separately for both of them.
