BOSS Audio Systems 6x9 Car Speakers CH6930B — 3-Way Coaxial Pair, 400W Peak, 92 dB

The BOSS Audio Systems CH6930B are 6 x 9 inch, 3-way coaxial car speakers built to deliver up to 400 watts peak power in a compact, factory-fit friendly design.

If you want a direct replacement or an upgrade for standard 6x9 openings, the CH6930B pair combines a poly-injection woofer, rubber surround, dedicated midrange cone and a piezo tweeter to cover 50 Hz–20 kHz with 92 dB sensitivity. These 4-ohm full-range speakers are sized and shaped to fit common door and rear-deck installations while offering a rugged stamped basket and a 1-inch voice coil for durability. A three-year online dealer warranty is available when purchased through Amazon.com.

How will these speakers change my in-car sound?

They expand frequency coverage compared with single-cone designs by splitting low, mid and high duties across dedicated elements. Expect clearer mids and brighter high-frequency detail without adding external crossovers.

• 3-way coaxial layout: woofer, midrange cone, piezo tweeter for broader clarity
• Frequency response spans 50 Hz–20 kHz for balanced reproduction
• 92 dB sensitivity yields loud output with modest power
• 400 W peak handling for short dynamic peaks when matched with appropriate amplification

Will these fit my vehicle and how do I mount them?

Dimensions and mounting specifications match many common 6x9 factory cutouts, but measure your door or deck opening to confirm. Mounting depth and hole size are listed so you can check clearance behind panels before installation.

• Overall dimensions: 4.3 x 10.2 x 7.4 inches for planning fit
• Mounting depth: 3.2 inches — check for obstructions behind panel
• Mounting hole footprint: 8.9 x 6 inches — verify against your vehicle template
• Item weight (pair): 6.2 lbs — standard for 6x9 coaxials

What materials and specs affect durability and performance?

The CH6930B uses a poly injection cone and rubber surround for resilient low-frequency response and resistance to moisture. A stamped basket and 1-inch voice coil help with heat dissipation and long-term reliability during moderate driving levels.

• Poly injection cone for consistent stiffness and controlled bass
• Rubber surround resists weather and maintains excursion control
• Stamped metal basket for structural strength and mounting stability
• 0.75" piezo tweeter and 2" polyimide midrange for crisp highs and defined mids

Can I power these with my factory head unit or aftermarket amp?

These 4-ohm speakers are relatively efficient at 92 dB, so many factory head units will produce usable volume, but they reach best performance with an external amplifier. Use the amp to maintain headroom and reduce distortion at higher listening levels.

• Nominal impedance: 4 ohms — compatible with most car amps and radios
• High sensitivity helps with lower-power radios; amp recommended for cleaner high-volume sound
• Peak power 400 W — RMS handling will be lower, match amp gain carefully

Who this is for: The CH6930B pair suits drivers seeking a direct-fit 6x9 upgrade that improves clarity across highs and mids without complex crossovers. It's a practical choice for anyone replacing worn factory speakers, owners who want louder, clearer sound from their door or deck openings, and installers who need a durable, warranty-backed component for everyday vehicles. Professional installation is recommended to ensure correct fit and wiring and to preserve the warranty.
