Enjoy JBL sound
JBL's GX628AM 6-1/2" coaxial speakers flaunt a contemporary look that's backed by a legendary commitment to excellent sound. The speaker's patented Plus One™ structure extends the surface area of the polypropylene woofer cone to give you a better low-frequency experience. And an edge-driven tweeter expands the high-frequency range, so you'll hear musical details that you never heard from your old speakers.
The GX628AM's low-impedance design safely draws more power from your car stereo or amp to give your music extra punch. JBL has also included a tweeter deflector to compensate for the diversity of car interiors. With high-frequency soundwaves guided more directly toward your ears, your music gains a truer, more dynamic sound.
A match for any system
These 2.3-ohm speakers are sensitive enough that you can power them with an aftermarket stereo, but you'll get even better results feeding them power from an outboard amp.

Plus One Woofer Cones: The Plus One speaker cones offer more surface area than other speakers that fit in the same size opening. This is accomplished by using a new basket design and hi-roll surround. The result is greater bass output and an increase in efficiency.
Edge-Driven Dome Tweeter: Each speaker's edge-driven dome tweeter rotates, and uses Harman's proprietary tweeter deflector to optimize the off-axis performance.
Size Classification Note: These speakers are marketed as 6½; they will fit standard 6½ speaker openings, but do not use the industry standard bolt pattern (then again, neither do many car manufacturers at this point). Without using an adapter bracket or drilling new screw holes, the speakers fit many standard 6¾ applications. The included brackets adapt the speakers to standard 6½ three hole, Ford four hole, and a variety of oversized 6¾ installations. If new screw holes are drilled in the mounting surface of the car, it may be possible to mount the speakers in many of these applications without the brackets. (When using the brackets, the mounting depth is 1.801" and the mounting height is 1.022".) Please enter your vehicle information to confirm fit.
High-Output Design: The 2.3Ω voice coil design compensates for the high in-line resistance of small gauge factory wiring, extracting more power from factory (or aftermarket) receivers. This results in clearer, richer sound for the listener.
