Hit the road with the big, rich, detailed sound the JBL® brand is famous for. In your car. Yes, your car. In addition to the serious bass of a Plus One® woofer cone, an edge-driven My-Ti™ super tweeter produces extended high frequencies like the best home audio speakers do. This is attention to detail rarely given to car audio. And it changes everything.

Product Features
Patented Plus One® woofer cone
The JBL-only Plus One® woofer cone is exceptionally stiff and lightweight with up to 25 percent more active surface area than you’ll ever find on competing models of the same size. You get an audible boost in bass output and efficiency.
Home theater-quality tweeter
Listen loud. It’s a high-bandwidth, edge-driven dome tweeter with a large voice coil, like high-end home audio loudspeakers. The My-Ti™ construction (a proprietary Mylar-titanium composite) delivers great power handling. Extended high frequencies. And seamless integration with the woofer.
More true sound from built-in crossover network
By using a built-in crossover network with advanced high and low pass filters, the GTO6428 creates a smooth transition between the woofer and tweeter. The result? Midrange vocals that sound so natural and lifelike, you’d think the artist was sitting in the passenger seat.
Can be safely driven by any head unit
The GTO6428 is compatible with aftermarket head units and factory-installed systems. Designed as replacements for impotent factory-installed OEM speakers, the GTO6428 is easily installed without any special tools or modifications.
True 4-ohm topology performance
For the most powerful performance, the GTO6428 makes the best use of any amplifier by providing an optimum 2-ohm load. It uses a voice coil with lower impedance than that in a typical speaker to extract the most power and performance possible from all amplifiers engineered to drive loads of 4 ohms or less.
Outstanding audio output
This muscular speaker offers 120 watts of peak power handling. Hit the gas and have fun.
Easy installation in any factory location
Doing it yourself? The GTO6428 easily installs into nearly any factory 4-inch by 6-inch location without any special tools or additional modifications. You'll be listening to your new JBL® speakers in no time at all.
