CT Sounds Bio 8” Dual 2-Ohm Car Subwoofer – 300W RMS, 600W Max

Meet the CT Sounds Bio 8 inch Dual 2-Ohm Subwoofer

Designed for car audio enthusiasts who want deep, controlled bass in a compact package, the CT Sounds Bio 8 inch dual 2-ohm subwoofer blends a tight form factor with serious power handling. The dual 2-ohm voice coil configuration provides flexible wiring options for different amplifiers, helping you tune the bass response to your vehicle and music style.

At the heart of the Bio 8 inch is a 2 inch, 4-layer copper voice coil paired with a single-stacked motor assembly. This combination aims to deliver rapid performance and robust thermal handling during dynamic passages, while maintaining linear excursion for precise low end.

The advanced air cooling system helps manage heat during longer listening sessions, supporting consistent performance. The low carbon iron zinc bottom plate adds rigidity, reducing flex and unwanted resonance so the bass stays clean at higher volumes. These build choices translate to a subwoofer that can respond quickly to transients and reproduce bass with clarity across a wide musical range.

Core specifications

• 8” Dual 2-Ohm Car Subwoofer
• RMS Power: 300 Watt | Max Power: 600 Watt

Design and build

The combination of a robust voice coil, efficient cooling, and a rigid chassis supports clean bass delivery even during dynamic low-end passages. The metal bottom plate contributes to chassis rigidity, helping minimize unwanted vibration while the air flow system helps dissipate heat that can occur with high-demand music.

Real-world applications

• Upgrade a factory or aftermarket enclosure for tighter, more musical bass in everyday listening and aggressive tracks.
• Pair with a compatible amplifier to explore a wide range of bass response, from punchy kicks to deep synth lines.
• Install in space-constrained trunks or shallow mounts where a mounting depth of 3.82 inches fits your build.

Installation notes and potential setups

Plan for a 7.17 inch cutout and a 3.82 inch mounting depth to ensure a proper fit. Use appropriate hardware and provide adequate enclosure ventilation to maintain performance over time. Results will vary with enclosure type, amplifier choice, and vehicle acoustics.
