High-fidelity component car speakers for bringing life to your sound system.

The JBL® GTO Series high-fidelity automotive speakers feature innovative technologies that we’ve engineered for the environment and for the conditions in today’s cars to help them deliver exceptional sound. Using 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, the 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, and the I-Mount™ (U.S. patent no. 5,859,917) system for the tweeters in the component separates – provide even greater installation flexibility so you can achieve the ultimate in-vehicle sound experience. Easily installed and built to last, the JBL GTO Series speakers bring music to life in your car.

I am connecting GTO609c with an amp. Should I use the amp high pass feature to adjust the frequency or just full pass to the component crossover?

Asked by: cb85
Since the GTO609C has its own crossover, sending full-range signal or only those that the speaker will play will not make much of a difference with the speaker. It would help the amplifier, less strain on the amp, if you set its high-pass to only send the signals within the GTO609C’s frequency.

what amp should match with this speaker, also for gto609c. it is any difference in sound quality between gtr 104 and club 704 or look for gto 804ez

Asked by: FZRemover
The best way to do this is to look at each amplifier’s specifications: GTO 804EZ - 80W RMS x 4 channels, <1.0% THD+N @ 4-ohms GTR 104 - 100W RMS x 4 channels, <0.1% THD+N @ 4-ohms CLUB 704 - 70W RMS x 4 channels, <1.0% THD+N @ 4-ohms The GTO 509C and 609C can handle 75W and 90W RMS respectively. All this tells us that the GTR 104 can provide the most power and the cleanest sound at high volumes (<0.1% THD vs <1.0% THD for the other two). With its gain adjustments, you are certain that you will not overpower your speakers (GTO 509C and 609C).

Yes, there is an Owner’s/Installation manual in the box that comes with the GTO 590C. The Owner’s Manual is downloadable in this page, under the Manuals & Downloads tab.

hello i want o ask or those GTO509C speakers would  fit at the back of BMW E60 2009 thanks

Asked by: neo 1986
Hi Thank you for the question. As far as I can see from the webpages that have information about which speakers fit which cars. The BMW E60 should contain 4" speakers. So it is no good to install 5" speakers. If you have other question, Please contact Customer help-desk.

Can you please tell me the dimensions of the crossover, I have to hide it behind my door panel but I'm worried it's too big. Thanks
