JL Audio C2650 component speaker system

Component speaker systems (also called "separates") feature separate woofers, tweeters, and crossovers. Components deliver realistic sound with outstanding imaging in the car, making them the choice of serious audio enthusiasts.

Separate woofers and tweeters

Normal coaxial speakers, whether factory-installed or aftermarket, combining the woofer and tweeter into one speaker. It's a convenient way to get great sound from a single speaker opening, but the design of the woofer and tweeter are both compromised in this arrangement. Also, a tweeter mounted on top of the woofer cone will always, to some degree, interfere with the sound waves produced by the woofer.

In a component speaker system, the woofers and tweeters are mounted independently — each component can operate to its full potential, eliminating the problem of the tweeter impeding woofer performance. More importantly, independent tweeters can be positioned for optimum imaging and soundstaging, which results in better sounding music.

The crossovers

Component systems typically use passive external crossovers to achieve clean separation between the frequencies sent to the woofer and tweeter. The woofer and tweeter don't waste energy by trying to reproduce frequencies they're not intended to reproduce. As a result, you'll enjoy cleaner, more efficient sound reproduction.


High-quality internal components, like those in this crossover, make a big difference in the quality of your sound.

Many crossovers have extra input terminals to allow bi-amping. Instead of driving the woofer and tweeter with a single channel of amplification, you can connect two sets of cables, with each set carrying the signal from a separate amplifier (or amp channel). This way, both low-frequency drivers (woofers) and high-frequency drivers (tweeters) receive dedicated amplification. Look for this feature if you're planning to put together a serious high-performance system.

Give them the power they need

Often, component systems are designed to handle higher amounts of power than their same-brand coaxial counterparts. They'll work fine when powered by an aftermarket stereo, but they'll really sound their best when powered by an external amplifier. Keep this in mind when you're planning your system. If you don't intend to add an outboard amp, then make sure the component speakers are rated to perform well on just deck power.

    I have a 2000 Toyota 4Runner and I am looking to replace the entire radio and sound system would I be looking for component speakers to replace everything or 3-way/2-way?.

    John, While components generally give you better stereo imaging and a more detailed soundstage than full-range speakers, there are plenty of folks who find full-range speakers just as satisfying. We certainly have lots of high-quality full-range speakers to choose from. Without knowing what you will choose to power the speakers, it's difficult to say what will work best for you. Generally speaking, however, installation of component speakers is more challenging than full-range speakers. Call us on the number at the top of this page, and an advisor will be able to give you a better idea of what to consider based on your powering scenario and the dimensions of your factory speaker openings.

    i have 4.1 channel amplifier in my car . can i use component speaker also ????

    Shakeel, you should be able to connect component speakers to a 4-channel amp, but you'll want to make sure that the amp's power rating matches the power handling of the speakers. A good rule of thumb is that amp power should be within the range of 75-150% of speaker's max RMS power. So, if your speakers are rated 2-60w RMS, an amp should have minimum of 45w RMS per channel and a max of 90w RMS.

    I have a 2011 Nissan Frontier and want to put component speaker in all 4 doors, is this a good idea or is there a better idea. I plan to install Kenwood P709 6.5 speakers and a good amp, what would you recommend? I also have a Kenwood DNX6190HD head unit

    Michael, give us a call at 1.888.955.6000. An advisor will be able to help you sort out what the best layout for your truck will be as well as give you some advice based on our research on the Frontier. Generally speaking, components give you a better soundstage than full-range speakers, but installation can be a bit more challenging. Those Kenwoods, while great speakers, aren't an ideal fit for your truck, and depending on who regularly sits in those back seats, you may not benefit that much from components in the rear.

    Do component speakers have to be all the same set

  • Alexander Hrabe from Crutchfield

    Mike, if you're using an outboard crossover, then no, but make sure that none of the speakers you're using have inline crossovers. Otherwise, it's not recommended to break up a component set. They're designed to work optimally together, with the included crossover systems negotiating the balance between the woofers and tweeters.

    I have a 2012 Chevrolet Silverado Extended Cab. I recently purchased a jl audio jx1000/1d. I am hoping to use the amps maximum output. What 1 or 2 jl audio subs will fit behind the back seat? Also I am wanting to install a nice component pair of speakers in the front and a pair of full range in the back. What amp will power all 4 speakers and 2 tweeters. I want everything to be jl audio and I'm going to be using a KDC X998

    After connecting component woofer and tweeter via crossover what is the independence. 4 ohm? If i have a coaxial 6x9 4ohm connected to 1 channel and i add a 4ohm tweeter to it is it 2ohm now? How can i make it 4? My amp is too powerful at 2ohm load...

  • Alexander Hrabe from Crutchfield

    Adrian, impedance may vary from brand to brand. For the most part though, you'll find an impedance of 4 ohms for speaker sets. Check the Details tab of the speaker set in which you're interested, or give us a call. An advisor will gladly help you find the speakers that are right for your system. You can take the impedance for the set at face value rather than trying to break down the individual impedance for the woofer and the tweeter. Adding new tweeters does impact the impedance of those speaker channels, but that impact is almost negligible. This is because tweeters have tiny motor structures and play over such a narrow frequency range that they don't add much to the overall impedance load.

    2011 Silverado Crewcab without bose system, but does have factory tweeters in the windshield post. I had installed JL stealthbox with 12's wired to 1ohm, Memphis 1100/1 to push them, and a pioneer avh-x4700bs head unit. (I had stereo shop install) I decided to upgrade my door speakers, so I bought a pair of JL c2650 full range for the rear, and a pair of JL c2650 components for the front, along with a jx400/4 to push them. Should I replace the factory tweeters in the windshield post with the new JL's? JL recommends not putting them further than the 8 inches away from the woofer. Did I buy the proper amp considering I have 6 speakers from the factory with only 4 outputs from amp. Should I use the JL in line crossover that came with the 6.5 components, or use the pioneer head units crossover?

    Les, generally, using your factory tweeter locations makes installation easier, but if you're willing to alter your door panels, JL Audio points out (taking a look at JL Audio C2650 Evolution components manual for example), that ideally you won't want a distance greater than 8" between where you place the woofers and where you place the tweeters. Again, given the layout of your door, that may not be possible, which is why many vehicles use the A-panel or windshield column as a tweeter location. Perhaps the best advice in the JL Audio manual is to experiment with tweeter locations before committing to a final mounting location. In the end, the sound that pleases you best is the best sound there is. Re: the JX400/4, that amp will work with your speakers. You'll wire your tweeters to the included external crossovers included with the C2560 system.
