JL Audio C5-650

Top-tier car audio experience

JL Audio's Evolution™ C5 premium component speaker systems reproduce your music with impressive fidelity and power. Your music will sound smooth and balanced, from the splash of a cymbal to the thump of an electric bass, and everything in between.

The C5-650 component system features a pair of silk dome tweeters that broadcast all the musical details without a hint of harshness. JL Audio built the 6-1/2" woofers for extended cone travel so they'll move more air, putting more oomph in your music when the rhythm section kicks in. These woofers use the same patented cooling technology developed for the ZR Series speakers, allowing the C5 speakers to play with a wide dynamic range at all volumes.

The C5 crossovers feature 4-position tweeter and 3-position midrange levels that give you 12 possible adjustment combinations for exceptional control over the final sound.

Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.

Woofer Features

Cast Alloy Baskets: The Evolution C5 component speakers feature cast alloy woofer baskets, while incorporating JL Audio's patented "Elevated Frame" cooling system. This cooling technology, also found on the flagship ZR component systems and W7 and W6v2 subwoofers, allows air to flow directly across the top plate and onto the voice coil windings to greatly improve linearity at all listening levels.

Motor Structure: The DMA (Dynamic Motor Analysis)-optimized motor structure achieves outstanding linearity.

Woofer Cones: The cone and suspension elements were designed and manufactured by the world-famous Dr. Kurt Müller & Co of Germany. The speakers feature low-mass, mineral-filled polypropylene cones with butyl rubber surrounds. The cone and surround are inherently well damped to deliver an uncolored, neutral midrange without any coloration. The speakers are also equipped with symmetrical-roll, hybrid-weave spiders.

Power Handling: JL Audio publishes several power specifications for this speaker, 75 watts continuous power handling (RMS), 225 watts peak music power, and 25-150 watts recommended amplifier power (RMS). We've listed the conservative combination of 25-75 watts RMS in the specs table.

Tweeter Features

Silk Domes: The C5 component system's 3/4" silk dome tweeters are incredibly smooth on- and off-axis for accurate imaging and a big, stable soundstage.

Neodymium Magnets: The small neodymium magnets and small chassis give you excellent tweeter placement flexibility.

Performance: Each pair of C5 tweeters is tested and matched to within 1 dB of JL Audio's reference curve to ensure optimum system performance.

Mounting Options: The tweeters come mounted in JL Audio's RSR mounting system to permit precise angling of the tweeters after installation. There are five available positions for angling the tweeter inside the flush mount. The mounting dimensions are as follows:

  • Mounting Depth: 0.56" (1.67" screw depth)
  • Mounting Height: 0.36"
  • Frame Diameter: 1.758"
  • Cutout Diameter: 1.49"
Crossover Features

Two-way Crossover System: The C5 component system utilizes a true 2-way crossover system:

  • High Pass: On the tweeters is a second order high-pass filter utilizing premium Mylar capacitors combined with an air-core inductor. Four tweeter level settings are selectable via jumper pins: +2.0dB, Reference, -1.5dB, and -3.0dB.
  • Low Pass: The low-pass section features a first order filter with three levels of user-definable midrange presence: Low, Reference, and High.

Polyswitch: Polyswitch tweeter protection is incorporated into each C5 component system crossover system.

Barrier Strips: Connections to each crossover network are made via protected nickel-plated barrier strips.

Dimensions: The C5 crossover systems have the following dimensions: Width=3.367", Height=4.72", Depth=1.44"

Connection Note: The C5 component system comes with no speaker wire. Instead, a number of spade connectors and quick slides are included in the hardware pack to be crimped onto speaker wire you provide.

9 questions already asked

Can the woofer and tweeter both handle 75W RMS if they each have their own channel of amplification? I would have them connected to a dsp so they would have active crossovers.

I have the c5 with 120rms using a alpine x series amp. Clear loud and no short of amazing.
paul  Jun 10, 2020
They cannot but then an amp that is only getting part of the frequency range (the part meant for each driver) would not be outputting the full power on each channel. Typically, I recommend a 50W RMS per channel amp and be ready to adjust the gain as needed when using an active crossover with them

Why wont this "fit" in my 17 challenger doors at factory door location?
matthew  Jun 20, 2018
1 answer
The JL Audio C5-650 require a larger cutout diameter than what's available in the doors on the '17 Challenger according to our vehicle research file. Please contact an Advisor directly by phone (888.955.6000) or online chat for more details or to discuss your installation further.

Why wont these woofers fit my 17 challenger 6 speaker alpine doors?
matthew  Jun 19, 2018
1 answer
According to our research, the JL Audio Evolution C5 component speakers require too large of a cutout diameter (5.56") than what's available in the doors of your '17 Challenger (5.1"). For more details on fit and/or installation, please contact an Advisor directly by phone (888.955.6000) or online chat. Hope that helps!
david  Jun 24, 2018 (Staff)
If these come with a crossover, do I need to set it on my head unit and / or the amp or should they be turned off?
manoj  Jun 09, 2017
1 answer
You could run a high pass filter (between 50-75hz) at the amp or head unit (the crossover doesn't filter out sub frequencies from your woofers).
connor  Jun 09, 2017
I'm creating a custom enclosure for the C5-650's. How much cubic air volume is required for optimal performance of the woofer alone?

It's the best for my Camero I love them
mohammed  Sep 18, 2016
The JL Audio speakers are made to work in any given airspace so there is no specific amount you have to have. You'll just need the proper cutout diameter and enough mounting depth for the mid-bass driver to seat flush. I hope that helps. My Bio:

wht amplifier goes with the c5-650 speakers?
alexis  Jul 23, 2014

Thanks for your question. For information on selecting the best amp 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 between the amp models and help you make the best choice for your system.
