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.

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.

Witch amp for this speaker ?

Asked by: domitermi
Hi, and thank you for your interest! With a sensitivity of 95dB, GTO 620 will work fine with a GX-A602 amplifier, which is one of he least expensive models we have. This is true for all "normal" listening. If you want to push the 620s to their max, you need more power.

Will these work for motorcycle speakers in the front fairing. Will they stand up to weather? And what would be a small amp with high-power that I could pair with these?

Will these fit into a VW Golf 5 (2006, 1.6 fsi) ? Will I be able to open my windows completely?

Asked by: VladB
Yes, this should fit the lower front door or lower rear door of your car. Based on the data that we have for your vehicle, we are seeing no possible conflicts with your windows as to the speaker's depth.
