JL Audio's Evolution C2 Series speakers

Side view of Evolution C2 speaker JL Audio's Evolution C2 Series speakers bring precision sound to your vehicle. They'll reproduce subtle elements of your music like delicate woodwinds or soprano vocals, then turn on a dime to deliver the deep thrum of the bass or thunder of the drums.


Silk tweeter delivers smooth highs

Product Research

Features

Woofers: The JL Audio Evolution C2-600x coaxial speakers feature injection-molded, mica-filled polypropylene woofer cones with butyl rubber surrounds. Each woofer has a 1" voice coil on a Kapton Former, a symmetrical roll spider and a Ferrite magnet.

Tweeters: Each coaxial speaker features a ¾" silk dome, ferrofluid-cooled tweeter with a damping neodymium magnet. The edge-driven silk dome tweeter is smooth, detailed (on or off axis), and provides great overall performance. Silk is lightweight and great for high frequency extension and efficiency. It is also designed for durability in the extreme automotive environment.

Grilles: Front-loading protective grilles are included, with black steel mesh and satin silver accents. Electroformed logo nameplates can be positioned on the grilles or elsewhere in the vehicle, according to the needs of the installation.

Mounting: This speaker system is a perfect fit for many Japanese cars that will not accept a 6-3/4 speaker without modification. The basket features three and four-hole patterns that match many factory mounting locations.

Size Classification Note: Crutchfield has traditionally referred to this size speaker as a 6-1/2", while some manufacturers, including JL Audio, call it a 6". The slightly larger speaker that JL Audio refers to as a 6-1/2" (C2-650x) has traditionally been categorized by Crutchfield as a 6-3/4". Please enter your vehicle information to confirm fit.

Power Handling: JL Audio publishes several power specifications for this speaker, 60 watts continuous power handling (RMS), 225 watts peak music power, and 15-100 watts recommended amplifier power (RMS). We've listed the conservative combination of 15-60 watts RMS in the specs table.

Q
Do these speakers need a amp?

Need probably not but you will not get what your paying for without one. Im running an alpine power pack 45w i believe. The speakers are clear and loud. If you have no plans of doing an amp get a lesser speaker. Most head units or factory amps only push 13-25w rms. Thats just not enough power.

I recommend using an aftermarket amp. I'm currently using the JL Audio JD 400/4 amp to power these speakers. Factory car speakers are typically 2-ohm, but these C2-600Xs are 4-ohm speakers. If you use C2-600Xs with only your factory amp, then they'll be only half as loud as your stock speakers. Using an aftermarket amp will unleash their full potential.

No but they will definitely sound better with an amp
chris  Nov 19, 2020

The do not necessarily need an amp, but could benefit with use of an amp for longevity and sound quality. The specs for power needs are 15 Watts to 100 Watts per channel RMS. So if your aftermarket radio puts out over 15 Watts at the volume you mostly listen to then they should be fine. Most factory radios put out about 10 Watts max. Some may do more now, but be wary of car manufacturer claims of what their radios actually do. If you have a factory amplifier consult with the experts at crutchfield and they will steer you right.
