I've installed enough car speakers to know that if you're going through the effort of taking off your door panels and creating tweeter locations, you'll want to choose a well-built speaker system that's going to live a long life in your car. Well, you've landed on the right page — this JL Audio C2-525 component speaker system is about as sturdily built and smooth-sounding as it gets for the price.

Powerful woofers for satisfying sound

Framed by a stamped steel basket, the 5-1/4" mineral-filled polypropylene woofer delivers the low frequencies reliably play after play, giving a solid foundation to your favorite music. The butyl rubber surround supports a cone that's designed for extra excursion, giving extended low-frequency response. 

Silk tweeters and versatile crossover networks

The C2 3/4" silk dome tweeters gracefully handle the high-frequencies, broadcasting crisp musical detail evenly and without harshness. 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. Separate crossovers use premium components to direct the signal flow to your woofers and tweeters, and you can select from the three levels of tweeter attenuation to match the speaker system to your listening environment.

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

JL components for 2007 Expedition

Mike from Ooltewah, TN on 3/8/2019

2007 Ford Expedition

Verified customer (What's this?)
Verified employee purchase (What's this?)

JL Audio as always has great product. The woofers fit into the locations with the provided adapters. The tweeters fit into the factory locations using the surface mounts pushed in from the rear and held in place with silicone and back straps. Sound quality is excellent though the tweets are a little bright in the 0db setting. Unless you are using active crossovers you will likely need to drop them back to the -3db setting as I did. Great buy and quality for the entry level JL component kit.

Pros: Good quality and sounding product for a reasonable price.

Cons: Crimp connectors are fragile, especially the small one. Hard to push on without bending. Wish the would change to spring style for the woofer like the old MB Quarts.

Huge upgrade

Brandon from Kemah, TX on 8/14/2018

2008 Ford F-150

Verified customer (What's this?)
Verified employee purchase (What's this?)

Installed these along with C2-570s in the rear doors and a 400W 4 channel amp to power them. I have an 08 FX4 with the factory Premium sound so it already sounded pretty good. I was expecting an increase in volume and clarity but not like this. It sounds better than my buddies Bose system in his 15 GMC 2500.

Pros: Easy installation Sound quality Performance

Cons: None

I love the crisp sound of the JL C2-525 speakers I've installed in my truck . They blend perfectly with the Alpine tuner I had previously installed. The speaker adapting kit along with the wiring harness make installation so much simpler. Thanks

Great sound.

Jeramie from Boise,ID. on 12/2/2017

Verified employee purchase (What's this?)

These are really impressive speakers. But I am thinking I might move them to the back doors. And try to find something with more mid bass for the front. Great speakers though. I hear notes that I never heard with the stock system.

Pros: Very crisp and clean. Easy install with adapter plate.

Cons: I would prefer a little more mid bass.

Features

Woofers: The JL Audio Evolution C2-525 component speakers feature 5¼" 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 component set features ¾" silk dome, ferrofluid-cooled tweeters with a 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.

Power Handling: JL Audio publishes several power specifications for this speaker system, 60 watts continuous power handling (RMS), 225 watts peak music power, and 15-100 watts recommended amplifier power (RMS). We've listed the conservative combination of 15-60 watts RMS in the specs table.
