Description

Upgrade your car's audio with the BOSS Audio CH4230B Chaos Exxtreme 4-inch door speakers. Designed for drivers who want big sound without sacrificing space, these coaxial speakers deliver up to 225 watts per pair, filling the cabin with powerful bass and crystal-clear highs. The 3-way full-range design combines a poly injection cone for deep lows, a 0.5-inch piezo tweeter for sparkling treble, and a 1-inch polyimide dome midrange that reproduces vocals and instruments with detail from 100 Hz to 18 kHz. With a high sensitivity of 90 dB and a 4-ohm impedance, they work efficiently with most factory and aftermarket head units, giving louder volume without draining power. Their compact dimensions (2.4 x 5.3 x 5.3 in) and shallow 1.7-inch mounting depth fit standard door openings, while the 3.7-inch mounting hole matches common cutouts for a clean install. Durable rubber surrounds and a stamped metal basket protect the drivers from vibration, ensuring long-lasting performance. BOSS Audio backs each pair with a 3-year platinum online dealer warranty when purchased on Amazon, and professional installation is recommended for optimal safety and sound quality.

Compact 4-inch size and shallow 1.7-inch mounting depth fit easily into standard door locations; 3.7-inch mounting hole matches most cutouts.
