Our take on the JBL GT7-86

by Alexander Hrabe
JBL

Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

A cool upgrade

These GT7-86 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 the sound they make that matters, and true to their iconic heritage, these JBLs deliver.

How do they do it?

You'll gain a satisfying boost in sound quality from these 5"x7"/6"x8" speakers, thanks to JBL's patented Plus One™ architecture, which expands the surface area of the polypropylene woofer for impressive bass. 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 60 watts RMS, but with a design geared toward maximum efficiency, you'll gain superior performance even from a factory radio. Grilles are not included — factory grilles are appropriate for most installations.

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.

We stay on top of new products and technologies to help people make informed choices.

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, capable of producing a wide soundstage. 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.

Mounting Applications: JBL describes this speaker as a 5x7/6x8; it fits many 5x7 and 6x8 applications. Please check the Crutchfield Vehicle Selector to confirm fit.

Great Product

Written By Prelot, Idaho on Friday, September 12, 2014
Crutchfield Customer Review (What's this?)
 
Not as loud as stock but very very crisp sound. Decent highs, above normal lows, and a bass that can be felt. Overall a good product.
Pros:
Crisp clear sounds.
Cons:
Not as loud as stock. Turn the volume up 3-5 points more to get same loudness as stock.

Quick Swap

Written By Tom, Middleburg, FL on Thursday, September 04, 2014
Crutchfield Customer Review (What's this?)
 
Quick and easy swap with factory speakers. Sound great only problem is now I need a sub to compensate for the extra trebles. Speakers are very responsive at low to medium volumes. As volume increases highs really pick up and take over the soundstage.
Pros:
Look great, easy install in 2012 F150
Cons:
Have pillar tweeters so the really adds to the highs.

Great sound even w/o an amplifier

Written By JREwing, Janesville, WI on Saturday, August 30, 2014
Crutchfield Customer Review (What's this?)
 
I had it all - a new Kenwood head unit with bluetooth, a Spotify subscription that turns my smartphone into an endless jukebox of great music, and blown speakers. Well now, that's not going to work!

Problem is, most 5x7/6x8 speakers won't fit in a Ford Five Hundred's front doors without some kind of hackery, thanks to an unfortunate placement of a tie down for the wiring harness.

These JBL's were easy to install, thanks to Crutchfield's clear instructions and included wiring adapters. Once installed, the JBL's sound clean and crisp, with enough volume to risk a noise violation, this without anything more than the Kenwood's internal amplifier. In short, it's an upgrade I should have done two years ago when I bought the car.

It has a nice, tight bass response, but there's only so much you're going to get with 6x8's in the doors.
Pros:
Enough volume to irritate neighbors and law enforcement Crisp, clear sound and tight bass Actually fits in the front doors of a Ford Five Hundred
Cons:
If you want serious bass, get an amp and a subwoofer.
