Product Research
Features
Woofers: Each JL Audio C1 speaker features a mineral-filled, injection-molded polypropylene woofer cone with a rubber surround.
Tweeters: The 3/4" edge-driven, aluminum dome tweeters are damped by a silk surround suspension.
4/2 Hole Compatibility: Most 4" factory speakers use four mounting screws, however, in some vehicles, only two are used. The C1-400x's mounting tabs can be removed, allowing installation in 4-hole or 2-hole applications. Care should be taken handling the speaker after any tabs are removed because the broken edges may be sharp. Please enter your vehicle information to confirm fit.
Power Handling: JL Audio publishes several power specifications for this speaker, 35 watts continuous power handling (RMS), 105 watts peak music power, and 10-50 watts recommended amplifier power (RMS). We've listed the conservative combination of 10-35 watts RMS in the specs table.

Made my 2021 Ford Bronco sound amazing! All I did was replaced the front 2 in the dash with these and it sounds incredible. Physically fits easily. You need to get creative for the wiring, but the Metra 72-5600 adapter "works". It's not a perfect fit, but it is enough to fit snug and work.
