C6-650 6.5-inch (165 mm) two-way component speaker system
Two-way component system: 6.5" (165 mm) woofer paired with a 1" (25 mm) silk dome tweeter.
Drawing on technologies developed for JL Audio's flagship C7 speakers, the C6-650 combines a premium silk dome tweeter with a high-performance component woofer for refined, dynamic sound in an amplified system.
The 6.5" C6 component woofers use purpose-engineered cast alloy frames with Elevated Frame Cooling technology. A DMA-optimized, forged and machined motor system delivers strong midbass impact with very low distortion.
The 1" C6 component tweeters use edge-driven pure silk dome diaphragms for smooth high-frequency performance and excellent off-axis response. Neodymium motors and ferrofluid cooling provide high magnetic flux, improved reliability and extended response from a compact motor. Both surface- and flush-mount fixtures are included.
Each C6-650 system includes premium passive crossover networks with four levels of tweeter adjustment. Networks feature polyester film and electrolytic capacitors, low-loss air-core inductors and an advanced electronic tweeter protection circuit, all under a protective polycarbonate cover.
C6 Woofer Features
- Forged and machined motor plates with DMA-optimized geometries for linear motor force, outstanding midbass impact and low distortion
- Large-diameter, linear-profile flat spider for linear compliance and strong excursion capability
- Centre cap optimised for high-frequency response, ensuring seamless transition to tweeter response
- Oversized voice coil for extended power handling, reducing thermal compression and distortion at high listening levels
- Cast alloy frame with Elevated Frame Cooling
- Fine mesh grilles included
C6 Tweeter Features
- Edge-driven pure silk dome design for smooth high-frequency performance with excellent off-axis response and damping
- Neodymium motor for high magnetic flux from a compact design

About the JL Audio C6-650
From our tech experts at CEN
The JL Audio C6-650 is a 6.5" (165mm) 2-way component car speaker system, rated at 100W RMS and sold as a pair. Each pair uses cast-alloy-frame woofers and 1" (25mm) edge-driven silk dome tweeters, drawing on technology from JL Audio's flagship C7 range. A passive crossover with four tweeter level settings and electronic tweeter protection is included.
Who it suits
These suit drivers with a dedicated amplifier (25–150W RMS per channel) who want detailed, accurate sound from a component system. A more affordable 6.5" coaxial option is the JL Audio C2-650x; for the step up, see JL Audio's C7 Series.
Our tech experts advise
The woofer needs a 139mm mounting hole and 66mm mounting depth — measure your door cavity before ordering. At 4Ω, the C6-650 requires an external amplifier and should not be run directly from a head unit. Both surface- and flush-mount tweeter fixtures are included. Fitting is priced per vehicle; contact us about installation in Nottingham.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
Q: Does the JL Audio C6-650 include crossovers?
A: Yes. Premium passive crossover networks are included, with four levels of tweeter adjustment and an advanced electronic tweeter protection circuit.
Q: How deep are the C6-650 woofers?
A: The woofer mounting depth is 66 mm with a 139 mm mounting hole. The grille protrudes 25 mm from the mounting surface.
Q: What amplifier power suits the C6-650?
A: JL Audio recommends 25 - 150W RMS per channel. The system is rated at 100W RMS continuous.
