About the JL Audio C2-600X

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

Silk tweeter

The C2-600X 6-1/2" speakers feature rugged polypropylene cones that can handle high power without distortion, so you get full-bodied low tones you can really feel. The 3/4" silk dome tweeters serve up smooth-sounding high frequencies that won't tax your ears, adding a satisfying dose of realism to your soundstage. Built-in crossovers make sure your tunes play smoothly across the whole musical spectrum. JL Audio includes a pair of grilles for custom installations.

JL is always a great choice...

Excellent speaker, substantially better than the Kickers they replaced. I have JL speakers in other vehicles and a boat, they are all very good. In my opinion, this model lacks some of the high frequency response other models have, so I rate them four stars. That said, it could merely be a EQ setting.

Looked long and hard for a good set of 6.5 speakers for my Harley. Totally amazed at the sound quality. JL mx280 AMP pushing off stock head. You can feel the sound in the handle bars and crystal clear. I could not be happier.

Pros: Sound and clarity. Fit perfect with adapter rings.

Cons: Not a one.

A+ speakers "The Best"

Rabuckg from Lawton, OK on 5/15/2015

2004 Pontiac GTO

Verified customer (What's this?)
Verified employee purchase (What's this?)

Best sound I have ever heard in a 6.5" speaker. I have 4 of them, each handling 75 watts with nothing but supurb and clear audio. Once again, good job to JL Audio.

Pros: Tweeter flush with woofer rim and not to deep in the back (allows for great fitment in several cars), nice look to them, great sound and even handles a little bit of bass pretty well.

Cons: None

cheap product

chrisk from midland, tx on 10/7/2014

Verified customer (What's this?)
Verified employee purchase (What's this?)

speakers are junk. the grille where the jl audio emblem goes was not there, no mounting ,they were missing. just more cheap china junk. the old delco speakers sounded better. i have jl audio in another truck and they are ok so i got some for my suburban. for what i paid for them i wasted my money. they were to come with mounting brackets but Crutchfield sent me a radio install kit instead. had to wait another week for the mounting brackets. brackets had to be cut to "fit". over all experience was not a good one. no longer will i buy jl audio.

Pros: they fit with bracket

Cons: poor quality even for china made, not worth the price

Eh...good enough but.....

Hogie from Medford, OR on 3/16/2013

1981 Ford F Series

Verified customer (What's this?)
Verified employee purchase (What's this?)

Over all fairly good speakers. I'm a bit of an audio snob and I have other vehicles with much higher end speakers so the best I can get is 3 stars for sound. First couple hours of listening they were a little flat sounding but they woke up as they broke in especially the mid-bass. My only real beef with these speakers is at this price they should be made in the US and sound a bit smoother. They are made in China and for this sound and build quality they are on par with other Chinese made speakers at the $80-$100 range. It appears the reputation of JL isn't all it's cracked up to be.

Pros: Overall nice crisp mid and treble. Easy to install. Came with all hardware.

Cons: Bit pricy for Chinese made stuff.

Awesome Sound

Rick from LaPorte Texas on 10/28/2012

2002 Acura MDX

Verified customer (What's this?)
Verified employee purchase (What's this?)

I replaced the head unit and speakers on my JBL Equiped 2002 Acura MDX The sound is fantastic, very clean and crisp, incredible detail, but not overly bright or brassy when you play something very precise and detailed like Dire Straits Love over Gold or Brothers in arms the subtle details that comes through are amazing. and that is using the JBL amp and wiring

Pros: Incredible detail, yet warm sound

Cons: It now points out the fact I need to get a REAL amp and find a way to incorporate my A pillar tweeters (at higher volumes the bass gets slightly muddy - IN MY CURRENT CONFIGURATION they cost $ 90.00 a peice (still not a bad price for this quality)

JL Audio C2-600X

stanjr from Clarksville, TN on 4/5/2012

1994 Honda Accord LX

Verified customer (What's this?)
Verified employee purchase (What's this?)

Very good speaker. I bought it to put into the front doors of a 1994 Honda Accord. It fits if you don't keep the enclosure that is present with the factory speakers there...and if you drill two more holes (per side). I didn't need to use the grilles that came with the speakers, but that's because the Accord already had door panel grilles.

Pros: Very good sound.

Cons: None that I can think of.

These speakers fit like a dream in my 2011 Chevy Express van (along with the Metra 82-3048 brackets). After going through some issues with the factory speakers and brackets, I finally am enjoying my new sounds. Love the sound quality you get from these JL's!!

Great 2-Way Speakers For Nissan Frontier CC

Crutchfield from Slidell, LA on 7/7/2009

Verified customer (What's this?)
Verified employee purchase (What's this?)

I spent a lot of time researching 2 way speakers and I finally came to agreement on these and I am very glad I did. These speakers get LOUD, but maybe not as loud as others because they only run continuous at 60 watts, however they are perfect if you still want to be able hear after you get out of your car. I have them in my rear doors with the JL VR-525CSi components in the front hooked up to a 80 x 4 JL G4500 amplifier. These speakers took a little shimming to fit, but ended up working out for me and I would consider them to be affordable speakers that sound perfect when compared to others.

1991 Mustang instalation

Jason from Detroit, MI on 3/31/2009

1991 Ford Mustang

Verified customer (What's this?)
Verified employee purchase (What's this?)

I ordered these for my 1991 mustang GT even though they said they wouldnt fit in my car since the speaker was too deep and would hit the windowguide track. A simple modification fixed this and they fit with ease. The dont have as much bass as i was expecting but they scream i also added these same speakers in 5x7 in rear and 3.5 in dash. To make these fit all i had to do was add three washer inbetween the door and the window track screw simple harmless fix.

Erik from Louisville, Ky on 3/3/2009

Verified customer (What's this?)
Verified employee purchase (What's this?)

These speakers sound awesome and were marginally easy to install. I may be biased because I was previously listening to speakers from 1995 that were nearly blown anyways but JL really hit the mark with these. Installation was pretty easy although the speakers were too deep to fit into the premade slots in the door paneling.

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.
