I recently upgraded my car’s audio system with the JBL GTO939 GTO Series 6×9″ speakers and the difference is nothing short of astonishing. The robust 300W peak power handling ensures that these speakers deliver crisp, clear, and vibrant sound even at high volumes, making every drive a delightful auditory experience.The three-way coaxial setup is a game changer. The highs, mids, and lows are distinctly clear and well-balanced. The high-frequency response is particularly impressive, thanks to the well-designed tweeters. They reproduce the vocals and instruments with a level of clarity and realism that is hard to find in car speakers at this price point. Installation was breeze.The build quality is robust, embodying the durable and reliable reputation of JBL. The black finish gives a sleek and modern look that blends seamlessly with my car’s interior, adding a touch of elegance.Moreover, the patented I-mount system provides flexibility in mounting and ensures the speakers stay put regardless of the bumps on the road. The Plus One woofer cone technology is another standout feature, significantly enhancing the low-end response.In conclusion, the JBL GTO939 GTO Series speakers are a solid investment for anyone looking to enhance their in-car audio experience without breaking the bank. They exhibit a fine balance of aesthetic appeal, ease of installation, and exceptional sound quality that is bound to satisfy even the most discerning audiophile.

Edit: I’ve now had these speakers installed for almost 15 months, and they still sound incredible. I now have a Pioneer AVH-X2800BS with the EQ set on flat, going into a Clarion EQS-746 for EQ and pre-amp up to 7 volts, going into my Polk PA 330. This combo is working very well, as live tracks truly sound like being at the concert.The bass that comes out of these speakers blows my mind. At times, it sounds like there’s a 10″ subwoofer hitting the low notes with precision, but it’s just these two 6×9’s (I have my rears turned off). These speakers are everything you’d want in a car stereo!* * * *I’ve been using these for just over two months now. I have them set up with a Kenwood HD-458U head unit (http://amzn.to/1Myu4fc) and a Polk PA 330 (http://amzn.to/1MmyfHB) amp. The amplifier sends 100W RMS x 2, at 2 ohms, which is exactly the max these loudspeakers recommend. Although my head unit only has basic controls (bass, mid, treble, bass boost), I have still tweaked it to sound very good with these speakers.I am running only these two speakers in my truck – I’ve turned off the rear speakers.If you really want to get the most out of these speakers, I’d suggest getting a head unit with at least a 5-band parametric EQ, if not even a 10-band EQ. That’ll be my next upgrade, since my last head unit had a 5-band, and I was able to get even better results (with other speakers) with the sound tune.Sound Characteristics:Bass – These speakers are strong enough to produce almost the amount of bass you’d get from a 10″ subwoofer. I used to load my vehicles up with subwoofers, but I now prefer SQ over SPL, and these full-range speakers are perfect for that. You’ll get rich mid-bass and deep bass frequencies form these JBL’s – enough to fill the cab of any car.Mids – The mids are delicious, as shown when listening to Adele Live at Royal Albert Hall (http://amzn.to/1MmyH8K) or Jason Mraz Live: Tonight Not Again (http://amzn.to/1MmyJNQ). The singers’ voices just float up to your ears, as if you’re sitting in the front row. Vocal tones are rich and sonorous, although it really depends on how the source was recorded. Some tracks on Ed Sheeran’s + (http://amzn.to/20KJZNJ) make his voice sound a bit tinny, like it was recorded in a small barrel. These instances are by and large the exception, however.Highs – A few reviewers mentioned setting the switch on the speakers to -3dB, but after testing, I kept mine on 0dB. I like the extra highs, and when tuned properly, it doesn’t induce the scratching in my left ear that my tinnitus will activate when I listen to things too loudly. The highs in these speakers are so clear and pronounced, that even though my speaker location is in the doors right next to the floor, the sound stage is lifted all the way up to my head. This makes for some fantastic listening.A True LoudspeakerMy last setup was an active crossover 3-way setup with Polk DB6501 components, and amped (50W RMS x 2) Pyramid W64 6.5″ bass drivers, driven by an Alpine CDA-9835 (27W RMS x 4) in 3-way mode. Although the SQ was better in that setup, the JBL GTO938’s are enjoyable in a different way. They add vibrancy to the music with their full-range capability.These are truly an all-in-one solution for car audio, and if you’re willing to turn off the rear speakers and settle for just these loudspeakers up front (amped, of course), you’ll be very happy!

These are significantly better than the stock speakers I removed from a 2009 Tacoma. Overall a much improved quality of music.

Great
