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.
