Ultimate Car Audio by JBL

JBL—speaker of choice for the world's top recording studios, concert events and movie theaters, delivers a world class listening experience to car audio with the new Stadium speakers. Unmistakably JBL. The high output 2 ohm design extracts every watt of power from the amplifier or head unit enabling the patented Plus One™ woofers to deliver an impressive wallop for mega volume aficionados. Sophisticated crossovers coupled with soft dome tweeters produce smooth as silk highs with extraordinary detail even at the highest volume levels. An optional midrange speaker with bandpass crossover provides seamless integration with woofer and tweeter, transforming a two-way component system into a three-way system for another magnitude of sound. Rigorous OEM-level reliability testing provides peace of mind when it's time to crank it up for that inimitable JBL adrenalin surge.

JBL Stadium GTO 620 is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Great Midbass and Clear Highs! I was lucky enough to find 4 sets of these for all 4 doors in my 2011 Buick Regal with the Harmon Kardon system. They fit with minor cutting of plastic in inner rear door panels, front speakers fit with no alteration. I like the adjustable tweeter volume and swivel. They can take plenty of power. I can hear details in music I was missing for years and the bass is a nice compliment to the 10 in sub-woofer in the trunk. I've got my eye on some JBL 6x9's to replace the factory back deck woofers. These definitely need amplifier power to hear their full potential and my factory 2 ohm amp makes them sing.

Will these fit into 2018 TACOMA

Asked by: 86 DARA
Yes I just installed these in the rear doors of my 2013 Tacoma the 2018s haven’t changed sizes  Get the metra 6.5 universal Toyota adapters  82-8148   If your thinking of doing the front doors I would do a 6.5 component set since that’s what is factory   You will have to get 6x9 to 6.5 adapters though Also if you have the Jbl system these work great since those are also 2ohm

First- the Gx-a602 on 2-Ohm Power Output 85 Watts RMS x 2 channels so this is not enough if gto620 have 75w Rms ?? secend -If I connect them to radio without amplifier (temporary I am waitnig for amplifier) ,can I damage the speakers?

Asked by: domitermi
Hi Thank you for the question. Before you connect the speakers directly to you car radio you should check the impedance of the output. If it is higher then then the speaker impedance then you can damage the output of the radio.

Hello. Can i upgrade the stock speaker on nissan rogue with these speaker without damaging the stock radio?? Thanks

Asked by: El duro38
Based on our data on the Nissan Rogue, the Stadium GTO620 speakers does not fit with your vehicle without doing a custom install. Compatibility-wise if the stock radio is 2-ohm stable, then the Stadium GTO620 should work great with its High Output 2 Ohm Design.

Hi, i have a pioneer deh-4500bt, built-in amps 4x50W, would i need an external amp to use these? TA

Asked by: Lsdaddicted
Hi. No, for normal, everyday use, you will not need extra amplification, your Pioneer will do a fine job. If you demand ultimate volume and audio quality, a separate amplifier it the way to go.
