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

JBL® GTO 629 6-1/2-inch (165-millimeter) speakers handle a robust 180 watts peak power (60 watts RMS). This much power makes for an ideal match to systems powered with head-unit or factory-amplifier power levels. Even better, the speaker matches many of the GTO Series amplifier combinations. As a result, it can keep up with systems that feature one or more subwoofers. And its great power-handling specifications increase reliability over the lifetime of the speaker.

I see it says 3 ohm... would 4 ohm to 2 ohm amp run it? 

Asked by: Toeknee
The GTO629 being a 3-ohm speaker is advisable to be powered by a 2-ohm compatible amplifier. In other words, as long as your amp can handle a 2 ohm load, you will have no problem driving your GTO629 speakers.

Hi, Will this fit as front speakers for nissan altima 2008? Crutchfield website says it will not. The stock speaker has only 3 holes for screw so a bracket/adaptor maybe needed. Could you please confirm. Thank you.

Could I match these speakers with the GTO609C components in the front and these coaxials in the rear deck of my 2013 Honda Civic SI

Asked by: Cobrar5409
The GTO 629 has a rating of 60 watts, while the GTO 609c has 75 watts. 15 watts should be okay as it wouldn't have much impact on the output of the speakers.
