GTO939 is rated 5.0 out of 5 by 5.
Rated 5 out of 5 by from Great 6x9 crispy sound I buy these edition to my 4 jbl gto 609c I didn't install them in the car yet but I hook it up to my receiver. Which is Harman kardon avr 1710s used it on stereo mode. After breaking it in after 4 hours of playing I start pushing power on the speakers. Very nice bass. I play with the bass control to see what is the respond on the speakers. They hit nice bass. Very nice vocals also When you push the -db button by the tweeters makes a huge difference on the tweeter. You get very ear iching tremble which i like. Nice quality all around. I am gonna push mostly mid bass on these I have the s3 1224 for the deep bass. You can never have to much speaker

Rated 5 out of 5 by from Great Sound fits Lexus ct200h I have JBL's at home and have always admired their sound quality. I needed front door replacements for my Lexus 2016 ct200h. I'm glad I didn't take your advice stating this wouldn't fit. It does and works great!!! They play much louder with fuller bass off the OEM Head Unit with no need to replace with an additional amp at this time.

Rated 5 out of 5 by from Great Speakers for the price. I installed these speakers into my 2009 Sierra in boxes under the rear seats with the tweeters facing up. I purchased the basic 6 x 9 boxes and they fit near perfect under the seat securely. I have a 40 watt 10 year old Sony amplifier turned all the way up and these speakers scream. Due to the size of the little 12 x 12 boxes, the bass is nothing to really brag about but the mids and highs are as good as it gets. I plan on following up the 6 x 9's with a pair of JBL 12's to get the bass I need to compensate for them. I can tell you that the sound is amazing, No popping or tweeter squeeling. These speakers will not disappoint. I could easily add my kicker 300 amp to them but they are plenty loud enough with the 40 watts behind them. I must also mention that I am still using my stock stereo. With an aftermarket unit and added EQ, these speakers could be fined tuned to perfection. Spend the extra money and get them. ROCK ON JBL. ROCK ON.

Rated 5 out of 5 by from Worth every penny!!! Great sound for a 6X9 3way I bought them to replace stock 6X9 rear speakers in a 2011 Nissan Altima. They sound great and rattle the license plate frame!!! Now I don't have to turn the volume up all the way to enjoy my music. I listen to dance,rap,r&b, and latin music. All sounds good wit these speakers!!!!

Hello, I have a 2007 Toyota Camry hybrid w/factory JBL upgrade. I need to replace the rear deck and door speakers but I hear that the factory JBL speakers are 2 ohm. The tweeter and woofers of these 6x9 speakers are also split (4 wires to each speaker)

Asked by: floridalance
Since this is an inquiry with the factory installed JBL system, all support for these products are handled exclusively through Toyota. Unfortunately we are unable to assist.

I recently purchased the GTO939's and the GTO609C's for a total of 4 speakers. My current radio has a 200 watt peak or 50 watts*4. I need to purchase an amplifier and I need a recommendation for which JBL amp is best for my situation. Thanks.

Asked by: Cole H
The best that we can recommend would be our JBL GTR-104 and JBL GTR-7535, where the latter would be best if you plan to add a subwoofer to your system at a later date.

I recently installed pioneer 4200NEX in a 2000 Toyota Camry XLE which has JBL premium sound installed in it. The guy mentioned that both my rear speakers are blown and need to be replaced. Can I use these speakers to replace the stock JBL speakers?

Asked by: RajaTH
Being that the GTO939 speakers can handle up to 300 watts, they can certainly handle the 20 or so watts of power that your stock system currently puts out. So, if you are simply looking to improve the sonic quality of your existing system, putting these speakers in should do the trick. On the other hand, if you are trying to get more volume out of your system, you will definitely need these speakers and an amplifier, in order to increase your volume. OR, if you are putting these speakers in because you have blown your stock speakers, this is likely because your stock amp is not powerful enough for your listening taste. In this case you would have likely turned your stock system up too loud, causing distortion, and as a result, blew the speakers due to distortion. So in this case we would also recommend an amplifier as well.

I am looking to pair a RF 400-2 to the perfect set of 6x9s for the front doors of a 2014 Grand Caravan. A 400-4 will power the dash speakers and the rear. I am trying to get the fullest sound without a sub. What is the best mix of JBL speakers for this?

Asked by: Bluemayskye
The GTO939 can hadle 200 watts of RMS power handling. So as long as your amp has a power output of 200 watts per channel or less, these speakers will sound great with your RF400-2 amp.

This is for clarification.. can i use the gto 939 speakers with a 2-4 ohm stable amp? Would there modifications as regards wiring the speakers to the amp?

Asked by: Myie111
Hi! Yes, you can use an amplifier that is rated 2 or 4 ohms with the GTO 939. You do not need to do any modifications with the wiring and the setup. You just need to wire them the same way on how you usually wire car speakers to their amplifier.

Can I use this speaker to replace my factory ones (2013 Toyota Avalon Limited) JBL with navigation. Since you do not have 7 x 10 replacements for what you put in the car.

Asked by: 13avalon
As shown on this product’s page, when you select the "Does It Fit My Car?", the GTO 939 is one of the speakers that will not fit your 2013 Toyota Avalon Limited.
