Upgraded speakers engineered to enhance today’s car audio systems.

JBL® GTO Series high-fidelity automotive speakers feature innovative technologies that we’ve engineered for the environment and conditions in today’s cars to help them deliver exceptional sound. Using patented, carbon-injected Plus One® (U.S patent no. 7,548,631) woofer cones, fiberglass-reinforced plastic (FRP) frames, butyl rubber surrounds and fabric tweeter diaphragms, GTO Series automotive speakers are the ideal upgrade to any car’s audio system. GTO Series speakers, including component separates with woofer, tweeter and passive crossover, cover the most popular factory-replacement and aftermarket sizes. Other unique features such as UniPivot™ (U.S. patent no. 6,002,780) tweeter positioning and tweeter level controls on select coaxial models or the I-Mount™ (U.S. patent no. 5,859,917) system for the tweeters in the component separates provide even greater installation flexibility to achieve the ultimate in-vehicle sound experience. Easily installed and built to last, JBL GTO Series speakers bring music to life in the car.

GTO939 is rated 5.0 out of 5 by 3.
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!!!!

Can I use this speaker on my Jeep Renegade Trailhawk MY 2017? Thank you in advance for your reply.

Asked by: Fabio1964
It is highly likely that the GTO 939 would fit your 2017 Jeep Renegade Trailhawk. Though this is a new model and our website’s database is not yet updated with this car's specs to quickly check this, the older Jeep Renegades uses 6 x 9 speakers. To be certain, we recommend you check the specs of the factory-installed speakers and if it does cover the dimensions of the GTO 939, then it’ll fit with minimal or no additional modifications. Here are the dimensions of the GTO 939 – Mounting Cutout Diameter (in)8-5/8 Mounting Depth (in)2-13/16 Mounting Cutout Diameter (mm)219 External Diameter (in)9-9/16 External Diameter (mm)243 Mounting Depth (mm)71

I'm thinking about buying these for a new sound system I'm building. What amp(s) do you suggest for these and also some GT7-6s?  ps. If you have any better suggests speaker-wise, I'd love to hear it, so I can find the absolute best. THANKS!

Asked by: TristanKyzer
Absolutely. The GT7-6s has an RMS wattage rating of 45 watts. This means that any amp with a power output of 45 watts per channel or less will work fine with this speaker. At the moment, a 45 watt amp is not available. However, I can recommend the GX-A602, a 60 watt amplifier. As long as you don't crank it to the max, causing it to send distortion to the speakers, you will not have any problem. And for the other speakers that you will be including on this system check what best fits your car by using the "Find what fits your car" feature above, choose your vehicles make and model then select speakers. You can see there all speakers, including the GT7-6s, which is compatible or could fit your vehicle.

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.
