Product Research

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.

Customer Q&A

11 questions already asked

Q
What amplifier should I pair with these?
ken  Jan 23, 2025
1 answer
A
Hey Ken, I would go with JL's matching amp series for these speakers. I went with a 4ch in this case so we have the flexibility to add another pair down the road or we can always bridge those channels to push a small sub: https://www.crutchfield.com/I-rET1c402/p_13698361/JL-Audio-JD400-4.html?tp=35782

Q
I'm looking to install these speakers in my pop-up camper. Is there an optional grill that I can order or maybe a universal grill that will work?
justin  Jun 11, 2024
1 answer
A
JL Audio does not make a grille to cover these speakers. Also, we do not have a universal grille that will work with them. The closest fitting we offer is this 8" grille shown here: www.crutchfield.com/p_125G08/item.html
jason  Jun 11, 2024 (Staff)
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
1 answer
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.
andrew  Nov 14, 2022
1 answer
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.
thomas  Jul 14, 2021 (Staff)
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.
kristina  Apr 22, 2020 (Staff)

They work well without an amplifier.
