DC Audio Subwoofers & Enclosures
If you’re building real bass into your Squarebody, you need more than just a speaker in a box — you need output, control, and durability.
DC Audio subwoofers are built for high-output performance and clean low-frequency response. Whether you're after tight daily-driver bass or aggressive, head-turning output, DC subs are designed to deliver true RMS power the way it’s meant to be used.
We run DC Audio in our own builds because it performs under real load — not just on paper.
DC Audio Subwoofers
DC subs are known for:
• Strong motor structures
• High power handling
• Clean low-end response
• Built-for-abuse durability
• True RMS performance ratings
Perfect for:
-
Daily driven builds
-
High-output street systems
-
Off-road rigs that still need serious sound
-
Custom panel and side-wall installations
Whether you're running a single sub or a multi-sub setup, DC Audio offers options that can handle real amplifier power without sacrificing sound quality.
Subwoofer Enclosures
A great sub deserves the right enclosure.
We offer properly designed subwoofer boxes built to match:
• Subwoofer airspace requirements
• Ported or sealed applications
• Clean interior integration
• Hidden or custom mounting solutions
The enclosure matters just as much as the subwoofer itself. Proper airspace and construction make the difference between “bass” and real performance.
Built for Squarebody Audio Builds
Pair DC Audio subs with:
• Our Premium Lighted Door Panels
• DC Audio Amplifiers
• Proper wiring kits
• Custom console or side-panel installations
From clean hidden builds to aggressive full systems, we can help you design the right combination for your truck.
