  • Owner’s Manual
Head’s are going to turn when they hear the sound that pumps through the JBL GX Series speakers. But get in and “whoa!” they look incredible. Designed to fit most factory specs, the GX series flaunt a new HARMAN-proprietary tweeter deflector, they’re individually voiced, and have three-ohm voice coils for optimal power distribution. Add Plus One™ woofer cones, edge-driven soft dome tweeters and an ogle-worthy design, and you’ve got a speaker that does much more than deliver killer sound.
Product Features:
  • Plus One™ Woofer Cones
    Harman’s patented (US patent #7,548,631) Plus One™ polypropylene cones provide more overall speaker-cone area than other cones in its class — the result is higher sensitivity, increased low-frequency output and greater musical character.
  • Edge-Driven Soft Dome Tweeter
    Soft dome tweeters deliver a smooth high-frequency response and an increased power handling for highs and mids, which equates to more lifelike sound from vocals, cymbals, brass instruments and pianos.
  • Three-ohm DCR Voice Coils
    The majority of factory-speaker wiring is so thin that it can’t draw the necessary power for great sound. With low-impedance, three-ohm voice coils, the GX Series speakers can pull more power from the amplifier, which means a clearer, richer sound for the listener.
  • Frequency Response Up to 21kHz
    Hear what you’ve been missing — the JBL GX Series offers a frequency response that delivers the full-range response associated with exceptional sound.
  • Individually Voiced
    For most brands, off-the-shelf speakers and a cursory approval of frequency response curves are good enough. That’s not the case with JBL. We don’t only listen to our speakers against the competition — we voice them against each other to ensure each line has the consistent JBL sound signature that’s known and sought out by those who care about their audio. This is just part of an extensive development process undertaken by some of the best transducer engineers in the world to provide the finest listening experience at any price point.
  • HARMAN-Proprietary Tweeter Deflector
    Acting as a waveguide, the tweeter deflector allows for an angled, rotating speaker, which optimizes the off-axis sound performance. Because all cars are designed differently, this allows impeccable sound to travel throughout all locations in the cabin.
  • External Crossover Housing
    The GX component systems feature external crossover housings, which provide space for sophisticated circuits including an adjustable tweeter level control and advanced tweeter protection.
  • Affordable Pricing
    The JBL GX Series are all designed to give audio enthusiasts more boom for the buck — while they maintain a conservative price point, there is never a compromise in sound.
  • OEM-Level Reliability Testing
    JBL tests every speaker design to the same rigid specifications as the automakers, subjecting them to extreme conditions that would break lesser speakers. We freeze them, bake them, shake them, blast them with ultraviolet light and drive them at full power for days to make sure your audio investment lasts for years.

Any idea if the stock head unit in the 2013 Chrysler 300c (8.4 inch Uconnect) has enough power just to swap and use the stock amps?

Asked by: killerpig11801
The power handling of the GX 963 is 100W at 2.3 ohms, You'll need to check on the specs of the headunit if it would be compatible with it.

Hi, I got a question about this model (gx963). Could I install it in a small sealed box, with 10L volume (each speaker) or if it’s too small is better to be ported with this 10L? What is the right volume sealed/ported for each one of this? Thanks!

What is the minimum watts for these speakers? I put these GX963's in my front doors with a Kenwood head unit and they just don't sound good over 22 on the vol.

Asked by: 05 Dodge Ram owner
The average power handling of the speakers are 100W. It's possible to underpower the speakers if you go lower than 70-80W.
