About the JL Audio C1-650x

Alexander H.

Starter speakers like no other

After an extensive tour of JL Audio HQ, I got the opportunity to talk to their engineering and development team about the current JL Audio lineup and upcoming projects. Given all the work they're doing with premium car audio, I was surprised by how excited they were for customers to hear their workhorse C1 Series — speakers designed for drivers simply looking for a sensible factory speaker replacement, not necessarily an audiophile-grade solution. The reason for that excitement, once I heard it, made perfect sense — every JL Audio speaker must uphold the quality and sound associated with the name. You may be looking for something that's just listenable, but what you'll get with the C1 Series is an audio experience that puts it at the top of its class. And then, just maybe, you'll end up being a JL Audio fan for life.

C1-650x

An aluminum edge-driven dome tweeter helps define this C1 speaker's distinctive sound.

What sets C1 apart?

JL Audio designed the C1 Series C1-650x 6-1/2" speakers to be the very best they could be for the price. You'll find solid construction and finish, along with some eye-popping flair in its striking yellow mineral-filled polypropylene woofer. That woofer delivers impactful lows and is specially designed for a natural roll-off transition to the highs handled by the tweeter. And it's the aluminum edge-driven tweeter that gives the C1 Series its distinctive sound, setting it apart from other speakers at this price. You'll hear crisp detail in the high frequencies, incredible imaging, and minimal distortion no matter how you power them.

Why no grilles?

Most folks have no use for aftermarket grilles, opting to use their factory grilles for a streamlined look. With that in mind, JL Audio doesn't include grilles with the C1 Series, opting instead to incorporate those savings into building an all-round better speaker.

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.

Size Classification Note: These speakers are marketed as 6-1/2"; they will fit in standard 6-1/2" speaker openings, but do not use the standard 6-1/2" speaker bolt pattern. In order to install them in standard 6-1/2" speaker openings you must drill new screw holes. If new holes are drilled in the mounting surface of the car, no bracket is needed. If drilling in the car is not an option, the included brackets can be used, which have standard 6-1/2" mounting holes, the Ford non-symmetric four hole pattern, and non-standard 6-3/4" three and four hole patterns. Please enter your vehicle information to confirm fit.

Power Handling: JL Audio publishes several power specifications for this speaker, 50 watts continuous power handling (RMS), 225 watts peak music power, and 10-75 watts recommended amplifier power (RMS). We've listed the conservative combination of 10-50 watts RMS in the specs table.

Q
Why are these only available for front door, even though they are the same size as the back door of my 2007 tacoma double cab?
ezra  Feb 02, 2023
1 answer
A
The speaker locations are made differently for the back doors of your truck. There is less space between the speaker and the grille on the rear door panel. For help with selecting speakers to fit your vehicle, please reach out to our advisors via online chat or phone at 1-800-324-9695.

Q
Iâ??m interested in these speakerâ??s for my 2023 Chevy 1500 crew cab with no Bose system, do I need an amp?
omar  Jan 04, 2023

A
These JL Audio C1-650 components are a great choice Omar, and they will sound great on your factory radio's power. The C1's also have an in-line crossover for the tweeter so installation is a little easier than on other component sets. Since the JL's can handle 50-watts RMS you can always add an amp if you'd like, and you could even potentially use the JL C-1 6x9's in the below link as they fit your new truck's front doors too! https://www.crutchfield.com/p_13699046/JL-Audio-C1-690.html

Q
I'm interested in these speakers for my '20 Kia Sportage S. Under the "See important fit information," it states not without the Harmon Kardon; without satellite radio. My car does not have the Harmon Kardon system but DOES have satellite radio. Will these speakers still fit?? Thanks in advance.

A
These speakers will fit both the front and rear door locations in your Sportage. For additional help with selecting speakers for your project, please reach out to our advisors via online chat or phone at 1-800-324-9695.
zachary  Nov 14, 2022 (Staff)
Q
Is this like a plug and play speaker or are there modifications needed?
hxjdjs  Jul 12, 2022
1 answer
A
Depending on the vehicle it is going into you may need to do some modifications with a bracket or harness adapter. If you give us a call at 800.324.9695 to speak with an advisor, we can help track down what you would need to get those JLs installed.
arielle  Jul 13, 2022 (Staff)
Q
Can coaxial speakers be installed in a car that came from the factory with component speakers? I wish to disconnect the factory tweeter and just use the coaxial speakers for the entire frequency range. Since I am also using factory wiring, will this prevent these speakers from receiving all sound frequencies, or should they work just fine?
seth  Jun 29, 2021
1 answer
A
You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.

Q
The tool says that the speaker will not fit even though my car has the proper size cutout. Could the mounting depth be the issue?
matthew  Feb 04, 2021
1 answer
A
It could be mounting depth, mounting height, or a cutout/magnet diameter issue keeping these from fitting into your vehicle. I recommend contacting an advisor by calling 1-800-324-9695 to discuss your vehicle, check if you are up to installing these, and if not then get a recommendation on speakers that can fit
jason  Feb 22, 2021 (Staff)
Q
Is the c2-650x that much better than the c1-650x?
eric  Apr 22, 2020
1 answer
A
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.
