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


Woofers: The JL Audio Evolution C2-525x coaxial speakers feature a 5¼" injection-molded, mica-filled polypropylene cone woofer with a butyl rubber surround. The woofer has a 1" voice coil on a Kapton Former, a symmetrical roll spider and a Ferrite magnet. These carefully engineered cones deliver the right combination of stiffness, damping, and off-axis response. The speaker also provides adequate bass, thanks to its ample mechanical clearance, optimized suspension and balanced motor design.

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.

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.

I plan on putting 2 good speakers in doors of my 2000 Ford ranger and some bass tubes behind my seats. So Iâ??m looking for the best for high and mid range sounds, are these what I should consider? C2 525x?
[ Tim  Sep 12, 2021 ]

Thanks for your question. For information on comparing two or more models I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences and help you make the best choice for your system and your budget.

Can I purchase the grill covers for these?
[ Nathan  Feb 05, 2021 ]
1 answer
Unfortunately we don't carry any grille covers for these speakers.
[ Allison  Feb 23, 2021 ]  Staff
Would 20rms/80 peak watts from stereo be enough for good clean sound? I'm not trying to enter a competition I just want some good sound.
[ Shifter88  Jun 23, 2020 ]

That amount of power would be good for a moderate level of sound, I've found these speakers live up to their potential while being amplified. But for day to day listening, the stock power coming from an aftermarket head unit should work just fine for you.
[ Kyle  Jun 26, 2020 ]
They are an excellent sounding speaker. I put a set in our Semi, and the sound is nice and clear.

If you're a true audiophile then no. If you don't mind tweaking the head units eq until it sounds perfect to you then yes. I run an amp to my subs and nothing to my component speakers. I did swap my door speakers for some aftermarket speakers and it made a world of difference still powered only by the head unit. I suggest looking for one of the packages crutchfield has. Upgrade till it sounds good to you then go one more upgrade.
[ Jordan  Jun 24, 2020 ]
I used these with a Kenwood base that was 75 rpm max. I have had great sound ever since, and I didn't break the bank to get great tunes out of there speakers.
[ John  Jun 24, 2020 ]
Would be a great touch and cleaner sound for what you're looking for
[ Jared  Jun 24, 2020 ]
Are thise water resistance?
[ Cisco  Mar 23, 2019 ]
1 answer
Hi, I would say they are moisture resistant due to the poly construction. If you want a good water resistant speaker I would go with the marine application. Either one will not disappoint . I put the set you are asking about in the doors on a GMC truck. But I also have a set of the marine speaker in my motorcycle fairing. Both the same size. Also the folks at Crutchfield won't steer you wrong. Good listening Brian
[ Brian  Apr 03, 2019 ]
Will this fit 2002 Harley fairing?

I want to fit these in the rear deck of my 1993 SC400. I would have to make a new base to to bolt down for OEM placement. What diameter does the hole for the new base be for these to drop flush?
[ Mark  Jan 13, 2015 ]
1 answer
For details on fit or installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on if this will fit and what you will need for an installation in your vehicle.
