Welcome to China Future Sound. With over 20 years of expertise and ISO 9001 certification, we operate a specialized manufacturing facility for car audio enclosures, subwoofers, amplifiers, and marine systems.

We are a strict B2B manufacturer and do NOT engage in retail sales on Amazon or consumer e-commerce platforms. We exclusively partner with:

• Car Audio Brand Owners expanding their subwoofer enclosure lineup.
• Importers & Distributors seeking reliable, direct-from-factory suppliers.
• Wholesalers requiring high-volume custom box manufacturing.

Mode 1: Catalog Selection (Fastest & Cost-Effective)
Pick from our semiannual catalog updates. Molds and tooling are pre-established—simply add your brand logo and custom packaging for rapid 4-month market delivery.

Mode 2: Semi-Customization on Existing Models
Modify net internal volume, carpet color, baffle thickness, or port tuning on our proven enclosure platforms.

Mode 3: Engineering from T/S Parameters
Provide your subwoofer's Thiele/Small parameters and target vehicle space. Our acoustic engineers will calculate optimal net volume and port tuning from scratch.

Mode 4: Custom CAD/3D File Production
Supply your 2D blueprints or 3D STEP files. Our engineers conduct feasibility checks and proceed straight to precision CNC prototyping.

We provide comprehensive OEM customization across every structural and aesthetic detail:

• Enclosure Structures: Sealed, Ported/Vented (Slot & Round Ports), Bandpass with Acrylic Windows, and Ultra-Slim Under-Seat / Shallow Mount designs.
• MDF Board Options: High-density MDF available in 15mm, 18mm, 21mm, and 25mm thickness. Optional Baltic Birch Plywood for reduced weight. Double Baffles added for heavy-duty long-throw subwoofers.
• Precision Cutouts: Flush mount cutouts for 8", 10", 12", and 15" subwoofers (Single, Dual, or Custom Multi-Hole layouts).
• Surface Finishes: High-density non-woven trunk liner carpet (Black, Dark Gray, Red, Blue) or Heavy-Duty Polyurea Spray Coating for waterproof, scratch-resistant truck applications.
• Terminal Hardware: Gold-plated binding posts, spring terminals, heavy-duty push connectors, and custom port tubes.
• Branding & Packaging: Silk-screen logos, laser-engraved badges, embossed metal plates, printed gift boxes, and reinforced shipping cartons.

1. Quick Inquiry: Submit your request via Email or WhatsApp. Our B2B team delivers a structured quote and technical proposal within 24 hours.

2. Sample Fabrication & Refund Policy:

• Custom prototype samples are fabricated within 25–45 days.
• Samples require a sample fee plus air/express shipping costs.
• 100% Refund Guarantee: The sample fee is fully credited back toward your commercial bulk order.

Mass Production Lead Time: Standard bulk order production is completed within 60–75 days.

Minimum Order Quantity (MOQ): Standard MOQ starts at 300 units per model (Flexible for multi-category combination orders).

Strict Quality Assurance: Automated CNC panel routing ensures exact panel dimensions. Every unit undergoes airtight seal inspection, glue joint stress testing, and cosmetic checks before packing.

Trade Terms: Standard pricing is based on FOB Shanghai Port. All local port fees, loading, and export documentation before vessel departure are covered by our factory.

FCL vs. LCL Containers: Subwoofer enclosures are bulky items. A 300-unit order often approaches a full 20ft container (FCL). We provide exact CBM (cubic meters) and gross weight details for efficient container space planning.

Protective Export Packaging: Units feature reinforced foam corner protection and heavy-duty corrugated master cartons to guarantee zero transit damage during sea freight.
