About the JBL GX642
Stylish sound
The compact build of the JBL GX642 makes it a great fit for more factory openings.
Stylish sound
JBL makes speakers for trend-setters, those who want a car speaker that looks as good as it sounds. The GX642 4"x6" coaxial speaker flaunts a contemporary look that's backed by JBL's 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 midbass 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 little things that count
The GX642'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.

Features
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.
Balanced Dome Tweeter: Each speaker has a balanced dome tweeter. A semi-dome tweeter has a dome placed inside a cone. Balanced dome tweeters are semi-dome tweeters with equal reproduction area given the cone and dome portions of the tweeter.
Size Classification Note: The GX642 comes mounted on a standard 4x6 bracket (the most common 4x6 application). With the bracket in place the speakers can be top mounted in some Metric 4x6 applications, but most Metric 4x6 installations will require removing the bracket. (In addition to the four bolts holding the bracket in place, it's also glued to the basket and will likely break when removed.) Please refer to the Crutchfield Vehicle Selector to confirm fit in your vehicle.
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.

Sound loud and clear. I don't recommend baffles with these at all because they made mine rattle. Not much bass but the music clarity makes up for it aND a sub is an easy add on
