Our Custom Audio Box Services
Subwoofer Enclosure Design & Build
We design and fabricate subwoofer boxes that match your vehicle’s size, shape, and bass requirements. From sealed to ported designs, we consider your music preferences and available space for optimal sound pressure and clarity. We use advanced design software and in-house measurement tools to ensure precise internal volume and acoustical performance.
Trunk-Mounted Custom Audio Boxes
Trunk solutions for sedans and hatchbacks are crafted to deliver powerful sound while maintaining trunk functionality. We provide sleek, carpet-matched enclosures that offer superior bass response without crowding your cargo space. Custom trim and optional lighting can also be added for enhanced visual appeal.
Under-Seat Enclosures for Trucks and SUVs
Many truck owners opt for under-seat subwoofer boxes to preserve legroom and maintain cabin storage space. Our low-profile designs are ideal for dual-cab and crew-cab setups, ensuring deep bass without compromising visual bulk. Reinforced mounting ensures stability even on rough terrain or during heavy use.
Marine and Off-Road Audio Box Builds
We design and build rugged audio boxes that are designed to withstand dust, water, and extreme heat. These enclosures are marine-grade and weatherproof for long-lasting outdoor use. Stainless steel hardware and vibration-resistant construction provide peace of mind in extreme environments.
Fiberglass Molded Enclosures
For customers seeking a true showpiece, we offer fiberglass-molded audio boxes. These high-end options enable the creation of complex shapes and custom finishing, ensuring a seamless integration into your vehicle’s panels. This service is ideal for show cars or anyone looking for a fully customized audio aesthetic.
Amplifier and Audio Component Housing
We also create matching housings for amps, capacitors, and crossovers. These additions enhance airflow, reduce clutter, and improve the visual appeal of your audio setup with neatly secured components. Custom housings protect electronics from vibration and overheating, extending the life and efficiency of your system.
Benefits of Custom Audio Boxes
Tailored Acoustic Performance
Generic audio enclosures often fail to utilize vehicle acoustics effectively. Custom audio boxes are designed to match the exact dimensions of your vehicle, optimizing resonance and bass output for a more immersive, high-fidelity listening experience. By aligning the enclosure’s volume and port tuning to your subwoofer’s specifications, we ensure that every note hits with clarity and precision.
Space Optimization
Our custom designs maximize the use of available space in your trunk or cabin. Whether it's a compact sedan or a full-size truck, your audio system will fit perfectly without sacrificing storage or passenger room. This ensures you get impactful sound without clutter or compromising the original design of your vehicle.
Enhanced Bass Clarity
Mass-market subwoofer enclosures often distort at higher volumes. With custom-built boxes, airflow and port tuning are carefully controlled, resulting in deeper, tighter bass with minimal distortion—even at peak output. Each box is acoustically engineered to complement your speaker’s performance curve, eliminating weak frequency zones and unwanted resonance.
Seamless Aesthetic Integration
Our custom boxes are designed to look like they belong. Using materials and finishes that match your vehicle’s interior, we create audio enclosures that blend in rather than stand out, offering a clean, factory-style finish. This enhances your interior’s aesthetic without drawing unnecessary attention to the installation.
Durability in Harsh Climate Conditions
High temperatures and variable humidity can wreak havoc on poorly constructed materials. Our enclosures are made from high-grade MDF, marine-grade vinyl, and heat-resistant adhesives, ensuring longevity even in triple-digit temperatures. We also reinforce structural points and use corrosion-resistant fasteners to prevent warping, cracking, or premature wear.
Increased Vehicle Value
A high-quality, well-integrated audio system adds both enjoyment and potential resale value to your vehicle. Buyers recognize the added appeal of a professionally installed custom system designed to last. Well-built enclosures signal attention to detail and quality ownership to potential buyers.
