The JBL GTO629 6.5" Grand Touring Series Car Audio Speakers are designed to deliver high-quality sound with a robust 180 watts peak power (60 watts RMS). These speakers are an ideal match for systems powered with head-unit or factory-amplifier power levels and can keep up with systems that feature one or more subwoofers. The speakers feature a carbon-composite non-magnetic frame, 3-ohm impedance, frequency response of 53-21,000 Hz, and a sensitivity of 93 dB. The top-mount depth is 2 inches, and grilles are included.
