A cool upgrade

These GT7-5C component speakers from JBL have everything you want when shopping for a car speaker: an advanced design, quality materials, a cool look, and a practical price tag. But in the end, it's what they sound like that matters most, and true to their iconic heritage, these JBLs deliver.

How do they do it?

You'll gain a satisfying boost in sound quality from this component system, thanks to JBL's patented Plus One™ architecture, which expands the surface area of the polypropylene woofer for impressive bass. And the edge-driven dome tweeters handle a wider range in the high frequencies for more natural sound — vocals, in particular, benefit from a smoother transition from the midrange. The external crossovers direct the right frequencies to the each driver to ensure a balanced sound.

JBL built these GT7 speakers to handle up to 45 watts RMS, so they'll perform spectacularly with an aftermarket radio or amp, but with a design geared toward maximum efficiency, you'll get superior performance even from a factory radio. Grilles are included for a custom installation.

Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.

Product Research

Woofers
Tweeters
Crossovers

Woofers

Plus One Woofer Cones: The Plus One woofer 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.

Tweeters

Tweeters: The edge-driven dome tweeters are made of PEI (Poly-Ether-Imide). PEI is a polymer film, capable of producing a wide soundstage.

Tweeter Mounting Options: Using the supplied housings the tweeters can be surface mounted flat or surface mounted at an angle (no flush mount housing is included). Once mounted in the appropriate housing, the tweeters have these dimensions:

  Surface Mount Angled Surface Mount
Mounting Depth screw depth screw depth
Mounting Height 0.884" 1.844"
Cutout Diameter N/A N/A
Frame Diameter 1.8" 1.8" x 2.21"
Crossovers

Connections: The passive crossovers feature screw terminal inputs and outputs; they will accommodate bare wire or spade connectors up to 1/4" wide.

Tweeter Level: A switch in each crossover allows you to adjust the output level of the tweeter; choose 0 dB or +2 dB.

Mounting: Each crossover can be mounted using two of the included screws through two holes in the base.

Dimensions:

  • Length: 2.625"
  • Width: 1.825"
  • Height: 0.940"

Q
If I were to get component speakers for my 2012 Dodge Ram 2500, where and how would I possibly mount the tweeters? Do I need to build a fiberglass enclosure for them somewhere?
jordan  Jul 17, 2018

A
I don't know about your Ram, but my 2003 1500 has enough room to mount them in the front doors. It would be best if you could mount your tweeters in your dash if you can. Or if you don't mind seeing them you can mount them on your A-pillars. I hope this helps you out.

Q
are they compatible with OEM Bose amp which is 2 ohm.?
james  Jul 28, 2015
1 answer
A
I forwarded your question to an Advisor and they responded with the following: These speakers are 4-ohm which means they will need more power than your factory speakers. I'd recommend reaching out to an Advisor by phone or chat to discuss. They can pull up your vehicle, see what options there are, and help you find the best match for your system. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.
