Our take on the JBL GT6-6

If you want speakers that'll make the most out of the power they're given, JBL's GT6 Series speakers are a smart way to go. They're sensitive enough to perk up the sound of a factory radio, but tough enough to handle an outboard amplifier too. These JBLs will impress you with their powerful bass, clear highs, and strong output.

These JBLs will impress you with their powerful bass, clear highs, and strong output.

Oversized cones, powerful tweeters
The GT6-6 2-way speakers employ 6-1/2" Plus One polypropylene woofer cones — with 30% more surface area than most other 6-3/4" speakers — to dish out the lows with accuracy and strength. The vented motor design keeps the speaker cool and operating efficiently when you've got the volume cranked. Each 1" titanium-laminate tweeter projects highs that'll sparkle over the sound of road and wind noise.

Used these to replace the junk GM speakers in an Impala's front door. These sound, by comparison, awesome! The improvement is terrific! Granted they aren't DLS or Rainbow good but they aren't $300 plus dollars.

Pros: Great improvement over the factory GM junk speakers in an '06 Impala front door.

These speakers have great sound. Just what I expected. I had concerns about replacing a 2 ohm speaker with a 4 ohm speaker for the Camaro monsoon sound system. However it sounds great.

Pros: Sound great

Cons: none

JBL GT6-6 Very Solid Speakers

Anonymous from Carbondale, IL on 10/27/2013

Crutchfield Customer Review (What's this?)

Installed the JBL GT6-6 this week. The sound is clear and crisp. Well balanced clarity with treble and bass both well defined. Glad to have upgraded my Honda Ridgeline speakers, including changing out the dash tweeters with Infinity.

Pros: Clarity and separation of sound.

Cons: None

Great for the price :)

Overall I was very satisfied, installed them in my 2012 wrx with stock HU and there is a lot more miss and bass then there was on the oem.

Pros: Everything

Cons: Wish they had a bit more bass, but that could be attributed to my stock HU

Good speakers for the price. Definite upgrade over stock.

Pros: These speakers are durable, sound better than stock and are a very good value.

Cons: None so far.

Better than expected!

RobM from lancaster, PA on 7/9/2013

Crutchfield Customer Review (What's this?)

These speakers impressed me right away after installation. The bass was much better than the OEM speakers, the highs were very clear and they are alot louder than the factory speakers. My Saturn is limited to four 6 1/2" sized speakers, but with 4 of these and my alpine head unit all I can say is WOW! They far exceeded expectations. While there are other more expensive speakers out there, these may be the best "bang-for-the-buck" units! Fidelity is very good for the money.

Pros: good bass for size, punchy sound, LOUD, crisp highs

Cons: mid-range clarity not world class, but ok.

Nice Speakers

John R. from Weeki Wachee, FL on 7/3/2013

2011 Toyota Camry
Crutchfield Customer Review (What's this?)

These are a very nice upgrade over stock speakers. I am running these using a Pioneer FH-X700BT head unit (no external amp). I placed these JBL's in my doors and have Pioneer TS-D6902R (6x9) in the rear and stock tweeters in the dash it makes my 2011 Camry very happy and me even happier! For the money it was a great improvement and I am glad I did it.

Pros: -Price- Sound-

Cons: -Build quality seems kind of cheap ie: speaker terminals bend easily. But honestly at this price point they are probably on par with comparable brands.

Buy these

AustinC from Chattanooga, TN on 6/29/2013

I paired these with JBL 6x9s and an Alpine head unit in a 1994 Toyota Camry. They sound great, and you really can't do any better for the price. They sound like they cost a lot more than they actually do. Highly recommend these speakers.

Pros: Sound Quality, Price

Cons: The system may have been lacking in bass if I had not of paired them with 6x9s, but they have better bass than most 6.5s, especially in this price range. Hardly a con.

Surprising Bass

Chris L from Raleigh, NC on 6/28/2013

2011 Chevrolet Silverado 1500
Crutchfield Customer Review (What's this?)

I replaced a pair of Kicker DS525s with these - these have a bigger bass sound and it doesn't get too loose in the sound. They went in easily and are definitely a step up from where I was. I did have to readjust EQ settings as now the bass (with a subwoofer) was just too overwhelming in the cab of my truck. It also introduced a lower-mid that was lacking with the other speakers. Given that the previous ones were smaller, this was to be expected. The cool thing is that this addition rounded out the sound so now my music sounds fuller and is more enjoyable. Haven't tried them with rap - never will but with classic rock, dance, country, prog-rock - great all around sound and a fullness that definitely lacks with smaller sized speakers. A good choice for a pickup door. I would put them in again without a second thought.

Pros: Full sound Tight bass Responsive

Cons: Have to tone down bass if using subwoofer

Great upgrade

RichK from Charlotte, NC on 6/27/2013

1997 Volkswagen Jetta III
Crutchfield Customer Review (What's this?)

I'm really impressed by these speakers. I had just purchased a set of MTX Thunder Dome coaxials for my rear deck, and was about to buy a second set for my doors when I noticed that these were on sale. The specs looked good, the reviews were great, and JBL has a good reputation, so I bought them. They fit perfectly and sound great. Not crazy bright, and they have very solid bass for a 6.5" speaker. I'm very happy with them.

Pros: Sound great. Solid Bass, Very Efficient (sound good powered only by a good head unit). Fit perfectly in my Jetta.

Cons: None.

Excellent speakers! these made the stock radio develop mid range and bass the stock speakers were missing.

Pros: Excellent fit with the brackets


blown tweeter

Todd from freeburg il. on 6/23/2013

Crutchfield Customer Review (What's this?)

Bought these speakers in march have blown tweeter in one. These are excellent sounding speakers was a recommended by Crutchfield. I question the quality of these since I have 4x6 kickers in rear and no issues running at full range using alpine 149. My son has 4 kickers in his car and abuses the heck out of them. Called Crutchfield about problem said they would send new asked if I could upgrade to kickers cs they said yes I paid difference they are sending new and return shipping let you know how all turns out.

Pros: sound great

Cons: Questionable quality


PaulW from Guilford,IN on 5/12/2013

Crutchfield Customer Review (What's this?)

Speakers sound great and wire hook up was easy. Speakers were 1/4 inch smaller in diametr and need to slightly improvise. Works fine.



Great sound for the money

Crutchfield Customer Review (What's this?)

The speakers fit great in my sons 96 Jeep Grand Cherokee. Fit the openings perfect just had to drill new holes for the screws, no big deal. They sound great with the Alpine deck, they are tight but could use a little more bass, but they sound great for the price!

Pros: Overall sound is great, nice and tight.

Cons: A little short on the deep bass.

Great sound

These are not the best speakers available but for the money they sound great and have good mid range that I like.

Pros: Trusted brand, great sound

Cons: bass is not as good as the rest of the sound profile.

Great speakers for the price

Michael from Hallsville, TX on 3/29/2013

2008 Chevrolet Silverado
Crutchfield Customer Review (What's this?)

Speakers sound great in my Chevy 1500. Factory stereo pushes them well. Only noticeable difference from factory speakers is a little bit tighter bass. Only issue I had was one of the speakers wires that goes to the voice coil were touching and shorting out. I separated them with a screwdriver and haven't had an issue since. The bracket for the Chevy worked great just wished they would have supplied screws to mount the speaker to the adapter. After reading other reviews I added some weather stripping tape between the bracket and the door panel to keep it nice and tight.

Pros: Great sound for a factory stereo

Cons: Terminal wires touching

Fantastic upgrade!

Ben from Lenexa, KS on 3/29/2013

Crutchfield Customer Review (What's this?)

These speakers were a fantastic upgrade from my factory speakers. The bass is much more full. I really notice better sound quality in the midrange. Much more crisp.

Pros: Fuller bass, crisper mids and highs. Installation in my Silverado was super easy with the supplied bracket.

Cons: None so far.

1996 Grand Cherokee

Chester from Chicago,IL on 3/19/2013

1996 Jeep Grand Cherokee
Crutchfield Customer Review (What's this?)

I recently purchased A pair of JBL GT6-6 speaker for the front of my truck. The sounded kind of good but the rear needed to be replaced as well. So i purchased another set. They all installed very quickly and easily. I already know a little about stereos and installation. But Crutchfield also included panel removal, stereo and speaker removal instructions and free speaker wiring harnesses. The service level is great from Crutchfield my stereo sounds so good now. 10 times better. eventually i will use Crutchfield prouducts again to upgrade to an amp and subwoofer. Thanks Crutchfield!

Pros: The speakers fitment was well with little alteration. I only had to re-drill mounting holes.

Cons: Compared to what my system sounded like. I have no complaints

Totally Satisfied

Ben from Hansville,Wa on 10/15/2012

Crutchfield Customer Review (What's this?)

These speakers were exactly as advertised. Great sound at a reasonable price. They fit my Grand Cherokee speaker holes as promised and only required drilling of new holes. Piece of cake. It took more time to remove the door panels than mount the speakers and hook up with supplied wire harness adapter. I have purchased several items over the years and can't say enough about Crutchfield's products and service. I price checked these speakers elswhere online and couldn't find a better price, but even if I had I would have purchased here due to customer support and ease of installation with instructions and wiring adapters supplied at no extra charge! I even saved a few bucks by purchasing from "scratch and dent", which meant the corner of the cardboard box was wrinkled, that's it!

Pros: Awesome sound with clear crisp highs and good base response. With an older Pioneer Super Tuner 111 driving 4 of these door speakers, its all the sound these middle age ears want and more!

Cons: Zero

Good speakers for the money, rockford fosgate is always my first choice but if you cant afford them get these. Great highs with decent bass for a door speaker.



Great sounding speakers

Salvador from Long beach on 9/10/2012

Great sounding speakers. They capture the highs really well, i dont know about lows since i have a subwoofer but all together great quality for the price. My only complaint is the mounting hole dont look the same as in the display photo. They have 4 small handles that stick out which made them a little difficult to mount in my 2001 civic door. They fit better in my rear deck

Pros: Great sounding, good quality

Cons: Mounting not the same as photo

Love them! Great product!

Medium quality speaker

Sri from Suffield, CT on 9/1/2012

2011 Toyota Camry
Crutchfield Customer Review (What's this?)

Better than stock speakers but not top quality. The speaker is not very heavy. I also ordered polk 650s which was far superior than JBL. Speakers did not fit in correctly on the mounting brackets.



Very Impressed

RSOBS from Cleveland, OH on 8/13/2012

Really impressed. Crutchfield associated talked me into these as a match for a JVC double-din head unit. I've owned lots of car speakers, but these rank among the very best I've ever owned. For the price, unbelievable value with my head unit.

Pros: Super sound, imaging, not overly bright. Great midrange.

Cons: Probably not as much bass as one would expect with a larger speaker, but adequate for sure.

Upgrade speakers for 97 Camaro convertible

David from St. Charles, MO on 8/7/2012

1997 Chevrolet Camaro
Crutchfield Customer Review (What's this?)

I was looking to upgrade the factory speakers in my 97 Camaro convertible and found these JBL GT6-6 speakers to be a good value. I've already got some JBL home speakers that have sounded great for years, so I decided to go with these instead of trying another brand. Of course, the JBLs sound much better than the original speakers. I installed this pair in the doors without any problems at all. I'm considering getting another set for the rear panels, after I make sure that they will fit. There's less mounting depth available there because of the convertible top linkage.

Pros: Easy installation, perfect replacement for the factory speakers.

Cons: Decent bass, but not a thumper.

Good speakers

Paul from Disputanta, VA on 6/26/2012

1998 Volkswagen Jetta III
Crutchfield Customer Review (What's this?)

Very good speakers for the price. I installed two sets of these in my crappy mk3 jetta a while back with a jvc stereo and loved it. I would add a low wattage 4 way amp (45 rms x 4 would be best) to get the best clarity out of louder volumes. Unfortunately after spending a total of around $500 on my sound system im selling my jetta and I got a 2007 tacoma standard cab.... I intend on going all out on the sound system for my new truck!

Pros: Great price, very clear sound, good enough bass

Cons: none

Awesome upgrade

Great sound and efficiency, perfect upgrade for OEM system. I installed four of these in my Honda Ridgeline and they are a huge improvement over the OEM door speakers.

Pros: Price, efficiency, sound, value.

Cons: No mounting hardware?! Seriously, not a single screw or anything!

Did not fit.

Herman C. from Houston, Texas on 4/6/2012

Crutchfield Customer Review (What's this?)

Excellent bold low frequency sound and good mid to high. This 6 3/4" rear door speaker had to compliment high quality 6x9 front door speakers in a 2003 Jeep Grand Cherokee and they completely passed the test. They gave a clean bold presence from the rear to match the larger front speakers. I was completely satified with their sound quality. Thanks goes to the Cruthfield rep for making this suggestion to me, it was great decision. I now have the best sound in my car I've ever experienced.

Pros: Top quality speaker with great sound reprodution and a bold clean bass response.

Cons: None

2004 Toyota Sequoia
Crutchfield Customer Review (What's this?)

I replaced the front speaker in my 2004 Toyota Sequioa .The crutchfield instructions for panel removal as will speaker connection were very helpful. The speakers I purchased are ok but the Bass is very ftat but for the price I can't complaint . If you would like more Bass on the mid to high end of the Volume range this isn't the speaker for you. I received what i paid for. I will continue to buy from Crutchfield .Thanks

Pros: It sounds great on the low end of ther volume and the price was good as will.

Cons: The Bass is very flat and distorted at mid to high volume range.

Doing the job

bmonk80 from Asheville, NC on 3/5/2012

Crutchfield Customer Review (What's this?)

These are a massive improvement over the factory speakers in my van. I am only using them for the sub woofer portion and they are performing well. I do have to adjust the bass between listening to the news (need less bass) to music (need maximum bass) but I think that is more an issue with my factory stereo.

Pros: Great price good bass response

Cons: Mounting holes did not line up, I had to drill out the existing holes to get it to fit in. I hope that does not void the warranty.


jay from ashburnham, ma on 2/9/2012

Crutchfield Customer Review (What's this?)

Great choice for the price. Good highs and lows and great definition to the point that you can hear the subtle sounds in songs that you did not notice before. I have been partial to alpine products in the past and have never been disappointed, but I was looking for something more affordable and I can't complain about the overall quality of the speakers.



A nice upgrade -- long overdue

RobW from Boise, ID on 2/4/2012

2005 Saturn VUE
Crutchfield Customer Review (What's this?)

Replaced the stock speakers in a 2005 Saturn Vue with these. The stock speakers just sounded too muffled -- maybe years of car washes did them in. I was not motivated to replace the stock radio/CD player and chose these speakers based on their sensitivity. Get plenty of volume without distortion with the stock radio, with the volume at about 1/3 of max. Vocals are clearer now and my wife enjoys listening the radio once again during her commutes. She commented that the music beat was also more prominent than before. I left the stock tweeters installed, btw. The brackets that came needed some modification to work with these speakers, specifically you had to cut out the mounting tabs on the inside diameter of the brackets. Also, you need to provide the #6 machine screws and nuts to attach the speaker to the brackets. The grilles that came with speakers got tossed because there is no way to use them, but the 'JBL' symbol is easily removed from the new grilles and can be attached to your door with some double-sided tape that is provided. While I was installing the speakers I made a rain shield from a gallon zip-lock bag to divert any water from the speaker that might come down the window slot. The installation was done about a month ago and I am very satisfied.

Pros: They sound good. They work well with the stock radio. They fit the door (with the Crutchfield-supplied brackets) and required no drilling or heroics to install.

Cons: Screws not provided. No instructions on modifying the brackets. (At first I thought the wrong brackets had been sent.)

Great Product

Just installed these speakers in the front doors of my 2000 GMC Sierra replacing the stock units.What a great improvement!Tight bass for a small speaker and very clear highs.Easy install,did have to drill holes due to slightly larger size than factory units.I new this in advance do to the great information from Crutchfield.The complete process took about 1 1/2 hours.I purchased these speakers based on Crutchfields take on the product and the opinions from the previous reviewers.I am very satisfied with my purchase.

Pros: Tight bass and clear highs.Can't go wrong with Crutchfield.

Cons: None

Great speakers

Crutchfield Customer Review (What's this?)

I could not believe the difference, pure, crisp sound, love them. And the instructions fit to the tee! The sales person matched the speakers perfectly, he could have sold me a more expensive set but instead make a customer for life AND fulfilled my goals, good sound at a reasonable price. Thanks again.

Pros: Service, sound, satified

Cons: none


Robert T from sterling, VA on 1/25/2012

Crutchfield Customer Review (What's this?)

Mounting brackets for the speakers were not sent along with the speakers resulting in a delay to have the speakers installed. When the brackets were sent they were the wrong ones resulting in another delay. The speakers sound is good and the price was fair.



Great stuff!

Red Audio from Nashville on 1/6/2012

1999 Nissan Pathfinder
Crutchfield Customer Review (What's this?)

These speakers are a massive improvement over my stock paper clarion's ..obviously. They sound excellent all around,and a lot of it has to do with the soundproof rubber spray and stuffing I used in lower door areas.My stock screws are an issue,and the connector adapters were so tight I had to open and lube w/electronic grease.In that situation tighter is better,and luckily my patience kicked in. The speakers seem very well constructed..Being an Audio Engineer.I have always enjoyed JBL sound.I think this model has been out for a while,and the price is a tad high.Bottom Line-The front of my suv is SlammaJammin Rawkin!w/ only the head unit Amp! I like em!

Pros: Warm mids and highs that hit a sweet spot around (11)on my Panasonic 50 watt mosfet tuner volume! The Very round extended bass for a 6 inch cone!

Cons: I compared(online) this product to several other's..and got lost in the candy shop array of car audio bliss.I researched this motor magnet size and had expectations of it being bigger.Confused it w/another product.The screw holes are tight for my factory Nissan screws..However,I prefer tighter than looser in this realm.Again I had looked at an item,and thought the tweets rotated for sweet spot position on these.they don't.Luckily my application in the front doors..I can get by without.

Excellent Buy!

Mike from Delmar, MD on 11/4/2011

Crutchfield Customer Review (What's this?)

Excellent bass response for a 6.75" speaker. Clear highs, great sensitivity (93). Any stock head unit will drive these producing excellent sound.

Pros: Sensitivity (93), Bass Response, oversized cone, shallow depth

Cons: No hardware or speaker wires included

Product Research


Plus One Woofer Cones: Each speaker uses a larger cone than other speakers of the same size. This is accomplished by using a unique basket design and hi-roll surround. The Plus One design offers greater bass output and an increase in efficiency.

Mounting: JBL refers to the GT6-6 as a 6-1/2" speaker. The 5.63" cutout diameter, however, fits the industry standard for a 6-3/4" speaker. Please confirm fit using the Crutchfield Vehicle Selector before purchasing.

Titanium Laminate Diaphragm Tweeters: Each speaker uses a titanium laminate diaphragm tweeter for fast transient highs with lower distortion.
