The JBL GTO629 is a 6.5-inch two-way coaxial car speaker designed to produce clear sound from a head unit or amplifier capable of delivering up to 180 watts of power.

It uses JBL Plus One carbon-injected woofer-cone technology to provide increased cone area for stronger low-frequency output and employs a carbon-composite non-magnetic frame for long-term structural integrity.

The speaker is intended for use with head-unit or factory-amplifier power levels and pairs with many GTO Series amplifiers; it installs in vehicles with compatible 6.5-inch speaker openings.
