BOSS Audio Systems 3.5" Car Door Speakers CH3220B 140W

The BOSS Audio Systems CH3220B Chaos Series are compact 3.5-inch 2-way coaxial car door speakers engineered to deliver clear full-range sound and up to 140 watts peak power per pair for upgraded in-vehicle audio.

If you need a space-saving speaker to replace factory door speakers or to add clarity to a small car audio setup, the CH3220B offers a poly-injection cone, rubber surround and a stamped basket together with a 1-inch polyimide midrange for focused vocals and mids. These coaxial drivers fit into small mounting holes while providing a frequency response suited for daily listening and in-car environments.

How much power and compatibility can I expect from these 3.5-inch speakers?

The CH3220B pair is rated for 140 watts maximum power and is nominally a 4-ohm load, which matches most factory and aftermarket headunits and amplifiers. Sensitivity is 88 dB at 1W/1m, making them reasonably efficient for small speakers.

• Max power: 140 watts per pair (peak)
• Impedance: 4 ohms, compatible with common car stereos
• Sensitivity: 88 dB @ 1W/1m for reliable volume from head units
• Recommended: pair with a small amplifier for improved headroom

What are the installation dimensions and mechanical features?

These compact speakers are designed for tight spaces: the overall footprint and mounting hole suit many door and dash locations where larger drivers won’t fit. The package includes form factors that follow common car speaker cutouts for easier swaps.

• Dimensions: 2 x 3.5 x 3.5 inches — small, shallow profile
• Mounting depth: 1.44 inches; mounting hole: 3.1 inches
• Stamped basket and rubber surround for durable mounting
• Item weight: 1.7 lbs per pair, light for door installations

How do these speakers sound and what materials shape the audio character?

The CH3220B focuses on clear midrange and controlled highs thanks to a poly-injection woofer and a dedicated 1-inch polyimide midrange tweeter. The rubber surround and stamped basket help reduce unwanted resonance for a cleaner in-car presentation.

• Frequency response: 100 Hz to 18 kHz for vocal-forward playback
• Poly-injection cone provides tight low-mid response
• 1-inch polyimide midrange/tweeter enhances clarity and presence
• Rubber surround improves durability and reduces distortion

Who is this for? The BOSS CH3220B is aimed at drivers who need a compact speaker upgrade for factory locations, riders with small cars or dash spaces, and anyone looking for an affordable way to improve vocal clarity and midrange presence without major custom installation. These speakers are a practical choice for do-it-yourself swaps and for installations where space or depth is limited. BOSS Audio Systems includes a 3-year platinum online dealer warranty when purchased through Amazon.com; professional installation is recommended to ensure proper fit and safe operation.
