Overview

Our take on the JL Audio C2650

The C2-650 component system features 6-3/4" woofers with rugged polypropylene cones that can handle high power without distortion, so you get full-bodied low tones you can really feel. The separate 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.

Silk tweeter delivers smooth highs

The C2-650 component system features 6-3/4" woofers with rugged polypropylene cones that can handle high power without distortion, so you get full-bodied low tones you can really feel. The separate 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.

Outboard crossovers

JL Audio includes surface- and flush-mount hardware so you'll be able to install the tweeters in the best possible location in your vehicle. External crossovers, featuring 3-level tweeter control, make sure your tunes play smoothly across the whole musical spectrum.


Note: JL Audio describes this model as a 6-1/2" speaker. Most manufacturers designate this same frame size as a 6-3/4" speaker. For simplicity's sake, we list it as a 6-3/4" speaker.

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

Awesome sound. Highs and lows. Great for any kind of music.

Features

Woofers: The JL Audio Evolution C2-650 component speakers feature 6-3/4" injection-molded, mica-filled polypropylene cone woofers with butyl rubber surround. The woofer has a 1.0" voice coil on a Kapton Former, a flat symmetrical roll spider, and a Ferrite magnet.

Tweeters: The Evolution C2-650 coaxial speakers feature a 0.75" silk dome, ferrofluid-cooled tweeter with a damping neodymium magnet. Silk is lightweight and great for high frequency extension and efficiency. It is also designed for durability in the extreme automotive environment. Flush and surface tweeter mounting brackets are included.

Tweeter Dimensions:

  Frame Diameter Cutout Diameter Mounting Height Mounting Depth
Flush Mount 1.874" 1.620" 0.286" 0.916"
Surface Mount 1.692" Screw holes only 0.939" Screw depth only

Two-way Crossover System: The C2 component system utilizes a true 2-way crossover system with Mylar capacitors and air-core inductors:

  • High Pass: second order (12 dB/octave slope); three tweeter level settings are selectable via jumper pins: +2.0 dB, Reference, and -3.0 dB
  • Low Pass: first order (6 dB/octave slope)

Tweeter Protection: The crossover network has an electronic tweeter protection circuit built in; it monitors the current and disconnects the tweeter when it senses and overload. The circuit automatically resets once the overload is removed.

Crossover Wiring: The terminal strip will accept bare wire or spade connectors up to 0.31" wide.

Crossover Dimensions:

  • Width: 3.365"
  • Height: 1.445"
  • Depth: 4.732" (plus wire)

Connection Note: The C2 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.

Size Classification Note: Crutchfield has traditionally referred to this size speaker as a 6-3/4", while some manufacturers, including JL Audio, call it a 6-1/2". Please refer to the Crutchfield Vehicle Selector for the proper size of speaker for your vehicle.

Power Handling: JL Audio lists two power figures in the manual; 60 watts continuous power handling and recommended amp power 15-100 watts RMS. We've listed the RMS power recommendation in the specs table.

Always have had good experiences with JL equipment [ Dylan  May 23, 2016 ]
Great Quality [ RYAN  Apr 02, 2016 ]

Silk Done tweeters - JL Audio reputation - Price point [ Kevin  Jan 18, 2016 ]

5 questions already asked

Being a music purist I always go slightly overboard on all speaker wire. I used 12 gauge to the woofers and the tweeter, but 14 to 16 gauge is certainly sufficient for the tweeters. [ David  Jun 01, 2017 ]
18 [ Thongvanh  May 26, 2017 ]
I used 12 gauge for all due to the amount of power and distance I'm running. 14 would probably be sufficient, but I always err to 12. [ Jesse  May 26, 2017 ]
Hitting them with about 90 rms fills my Subaru with plenty of sound. Not drowned out by the pair of 12'a I'm pushing with lots of power [ Derek  Apr 27, 2017 ]
they get pretty loud when amplafied, super clean crisp sound. great stuff from jl audio. [ Antonio  Apr 26, 2017 ]
They get pretty loud. Especially if you have the right amplifier connected into them. [ MAURICE  Apr 26, 2017 ]
I have a 4 channel JL audio amp powering mine in a 2015 Tacoma. I have yet to turn it up all the way it gets too loud for my ears to handle. [ Brian  Apr 26, 2017 ]
I have an 2015 RAV4 and have theses speakers and 75 watt kicker amp and 51/2 kicker rear speakers and 250watt sub with stock head unit and it sounds great [ RUSSELL  Dec 30, 2015 ]
I think you will be quite happy with these speakers without the need for an additional amp or bridging. I am powering these speakers with the internal amp of an Avic Z150-BH head unit, which has similar power specs to the Avic4100. They have a great sound and plenty of volume, as long as you aren't expecting competition spl levels. I would recommend trying them out like this first ... you can always add an amp or bridge later, if you decide you need to. [ Keith  Dec 30, 2015 ]
These are sound quality speakers. I have front and rear components amplified with a alpine amp. In a 2015 Toyota Camry. Still not loud enough for me.. But are a very nice set if your not trying to get crazy [ David  Dec 30, 2015 ]
I added a 1000 watt 5-channel amp and they sound amazing. I recommend adding the amp. [ Anthony  Dec 30, 2015 ]
Hey Andrew in my opinion I would suggest that you put a amp those speakers to get the best sound quality ...I would say abot 60 too 75 watts rms to get the best sound from these..I personally have them on 100 watts rms and my amp is 1/4 the way up and they sound really good..not to say they would sound bed with the head unit but I know from my experience the amp will and more depth to the music.. [ Terrell Wilson  Dec 29, 2015 ]
I had best luck and sound running an amp,.... Of course costs a lil more but totally worth it! [ Scott  Dec 29, 2015 ]
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. [ Krissy  Jun 14, 2014 ]  Staff
