BOSS Audio Systems 6.5in Coaxial Car Speakers CH6520

The BOSS Audio Systems CH6520 are 6.5-inch coaxial car door speakers delivering up to 250 watts peak power with a 1-inch tweeter for clearer highs and robust midrange.

These CH6520 Chaos Series speakers are a full-range, 2-way coaxial design built for direct replacement in many factory car door locations. They combine a poly injection cone, rubber surround and a stamped steel basket to balance durability and sound clarity. With a nominal impedance of 4Ω and a sensitivity rating around 90 dB, they’re tuned to perform well with most factory head units and aftermarket receivers when installed properly.

How do these speakers improve everyday in-car listening?

The CH6520 pair refines midrange presence and sharpens treble detail through a dedicated 1-inch tweeter while maintaining punchy low-mid response from the poly cone. Their 90 dB sensitivity helps them sound louder with less amplifier power, making them a practical upgrade for daily drivers.

• 1" tweeter for clearer vocal and instrument highs
• Poly injection cone delivers tight midbass and quick transient response
• 90 dB sensitivity reduces need for high-power amplification
• Coaxial layout keeps installation straightforward for door replacements

Will these fit my vehicle and how big are they?

The CH6520 speakers are sized for common 6.5-inch factory openings but always verify dimensions before purchase. Their overall diameter, cut-out size and depth allow them to replace many stock door units without extensive modification.

• Installation hole diameter: 5.51" / 140 mm

What materials and specifications affect durability and sound?

Construction choices such as the rubber surround and stamped steel basket increase long-term reliability and keep resonance controlled. The electrical specs outline how they behave with common systems and help you match them to amplifiers or head units.

• Rubber surround for moisture resistance and longer life
• Poly injection cone for consistent sound under load
• Stamped steel basket for rigid mounting and reduced distortion
• Frequency response: 100 Hz–18 kHz ±3 dB; 6 dB/oct high-pass filter
