GT7-4 profile

The compact design of the GT7-4 makes it a fit for a wide variety of cars.

A cool upgrade

These GT7-4 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?

In spite of their size, these 4" speakers always kick out plentiful midbass, thanks to their patented Plus One™ architecture which expands the surface area of the polypropylene woofer cone. Balanced dome tweeters handle the high notes with ease, especially when powered by an aftermarket radio or amp. JBL built these GT7 speakers to handle up to 30 watts RMS, but with a design geared toward maximum efficiency, you'll gain superior performance even from a factory radio. Grilles are included for a custom installation.

  • 4" 2-way speakers (pair)
  • polypropylene Plus One™ woofer cone with foam surround
  • balanced dome PEI tweeter

This JBL GT7-4 fit well on my 2001 Frontier. I replaced the stock speakers with these and the installation took no time ,did not have to mod to fit, sound very good I am happy with the products.

Pros: Fit good with existing mounting holes, no need to mod and sound is much better compared to the stock speakers.

Cons: The speak connector did not fit 100 % to the factory connector have to use zip ties for proper fit.

Crutchfield Customer Review (What's this?)

I bought a pair of JBL GT7-4s to replace my back panel speakers and I've had no qualms thus far. It has been about three weeks since I installed them and have observed a noticeable improvement in the sound quality compared to the standard stock speakers. The only problem I found is that if you break off a wrong screw clip good luck securing the speaker in your car. Overall I'm happy with the speakers and can't complain about the price.

Pros: Great sound Safe packaging Comes with everything you need

Cons: Detachable screw slots

Sharp focus possible with small JBLs

Kenneth from Yukon, OK on 9/7/2016

Crutchfield Customer Review (What's this?)

Good value, power/size, and grills look great - slightly shrill if not tamed a little - but also clean/clear. Running them 90 hz and up - sweet and hot , tilt at top lends sizzle when called for, but not kind to brassy recording with thin mids.

Pros: Size/power ratio is great, break off tabs gave me a perfect fit where it was not recommended - bonus!

Cons: None so far

not ok

2004 Nissan frontier stock speaker replacement. Direct fit with speaker wire plug adapter. Easy installation. Sound is slightly better than stock. Not amazing, but good for the price.

Pros: Easy installation. Decent sound for the price.

Cons:

Great sound for a 4" speaker

Crutchfield Customer Review (What's this?)

Very clean sound. Don't expect much bass from these (they are 4" speakers after all) but the sound is clear and puts off good highs. Definitely worth my money.

Pros: Good highs. Clean sound.

Cons: None to report.

economical

Chris from Georgia on 1/8/2015

Crutchfield Customer Review (What's this?)

Very impressed with the sound of these speakers. These were recommended by a Crutchfield agent to work with the Alpine Stereo that I was purchasing for my daughter's 1999 Jeep Wrangler. The only reason that I'm not giving it a five star is, I was told that everything needed for installation in this vehicle was included. The speakers are a different size than the factory installed. I had to modify by adding a bracket to secure the bottom of the speaker. Not a real big deal, but I would have thought this would be included.

Pros: Good sound, Good price

Cons: Did not include brackets for installation.

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 PEI (Poly-Ether-Imide) balanced dome tweeter. PEI is a polymer film that produces a wide soundstage for superior imaging. 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.

4/2 Hole Compatibility: Most 4" factory speakers use four mounting screws, however, in some vehicles, only two are used. The GT7-4's mounting tabs can be removed, allowing installation in 4-hole or 2-hole applications. Care should be taken handling the speaker after any tabs are removed because the broken edges may be sharp. Please check the Find What Fits Your Car application to confirm fit in your vehicle.
