The JL Audio C1-400x is an entry-level, high-value 4-inch coaxial speaker system designed to provide a massive step up in clarity and detail over factory-installed speakers. Part of the C1 series, these speakers are engineered for high-output performance and smooth response while fitting into tight spaces and behind factory grilles.
The C1-400x is built around a proprietary, stamped steel 4-inch frame and a DMA-optimized motor system to reduce distortion. It features a true edge-driven aluminum dome tweeter, which is a rarity at this price point. This design provides superior high-frequency extension and off-axis response compared to traditional balanced-dome tweeters often found in competitors' entry-level models.

Decent 4" coax
The only thing I had trouble with was putting on the provided terminals. The negative terminal is tiny and narrow. It was difficult to slide onto the connector on the speaker. It kept bending as I was trying to slide it in. Other than that, decent speakers.
