BOSS Audio Systems 4x10 Inch 3-Way Car Door Speakers

If you want to replace factory door speakers with a compact set that boosts volume and clarity, the CH4330 pair offers a three-way driver layout in a shallow-mount frame designed for many vehicle door openings. These speakers combine a poly injection cone, rubber surround and polyimide tweeter and midrange to cover a broad frequency range while keeping installation relatively straightforward.

How do these speakers improve everyday car audio?

The CH4330 focuses on louder, clearer playback across vocals and instruments without requiring large enclosures. A dedicated midrange and tweeter handle detail and presence, while the 4-ohm impedance and 90 dB sensitivity help the speakers work efficiently with most aftermarket head units and modest amps.

• Three-way design: separate tweeter and midrange for better clarity.
• 90 dB sensitivity for strong output at typical head unit power.
• 100 Hz–18 kHz frequency coverage for vocal and upper-frequency detail.
• Poly injection cone and rubber surround for durable, accurate cone motion.

Can these fit into standard car door openings and how deep are they?

Yes — the speakers are built for common door installations that accept 4 x 10-inch units and use a shallow-mount profile for tighter spaces. With a mounting depth of 2.5 inches and a mounting hole footprint of 9.4 x 3.9 inches, they suit many factory locations without heavy modifications.

• Mounting depth: 2.5 inches for narrow door cavities.
• Mounting hole: 9.4 x 3.9 inches to match typical door cutouts.
• Overall dimensions: 3.3 x 11.1 x 5.2 inches for easy alignment.
• Item weight: 3.9 lbs per pair, lightweight for door hardware.

What materials and voice coils are used for longevity and sound?

BOSS Audio built the CH4330 with materials chosen for reliability and consistent performance under car conditions. The stamped basket and rubber surround resist road vibration, and the 1-inch voice coil helps the driver manage power and thermal loads during extended listening.

• Poly injection cone resists deformation and keeps response tight.
• Rubber surround provides durability against temperature and moisture.
• Stamped basket reduces resonance for cleaner output.
• 1-inch voice coil for stable power handling and heat management.

How much power can they handle and what should I expect from performance?

The pair is rated to handle up to 400 watts collectively, making them suitable for higher-volume listening when paired with an appropriate amplifier. Sensitivity of 90 dB and a nominal impedance of 4 ohms mean they’ll produce strong sound with most modern head units and small amplifiers, though adding an amp will unlock fuller dynamics and headroom.

• Power handling: 400 watts per pair for powerful playback.
• Impedance: 4 ohms for compatibility with many car audio systems.
• Sensitivity: 90 dB @ 1W/1m for efficient sound output.
• Frequency response: 100 Hz–18 kHz covers mids and highs clearly.

Who is this for? The CH4330 set is aimed at drivers who want a straightforward upgrade from factory door speakers without major door modification: commuters, weekend drivers, and car audio hobbyists seeking improved vocal clarity and higher SPL from a compact 4 x 10" footprint. Professional installation is recommended to ensure proper fit, wiring, and safety, and BOSS Audio Systems supports these speakers with a three-year platinum online dealer warranty for added peace of mind.
