JBL GTO629 6.5/'' GTO 2-Way 360 Watts MAX Power Grand Touring Series Coaxial Car Audio Speakers Bundled with Alphasonik, GTO629+Alpha

Carbon-injected Plus One cones are larger than others in their size class, meaning they move more air and make more bass. Dimensions: Mounting Cutout Diameter: 5-1/16 inches. Mounting Depth: 2 inches. External Diameter: 6-1/4 inches
Patented UniPivot tweeter allows you to aim the sound at your ears, even when the speakers are mounted down low in the doors for a much more lifelike sound
A dual-level tweeter volume adjustment helps compensate for less-than-perfect speaker placement, and can even be set to suit your personal listening preference and musical taste
Low-impedance, three-ohm speakers compensate for the undersized wires found in many of today’s cars, and make the most of every watt your car stereo can deliver
Dedicated 12dB/octave, high-quality crossover components direct the highs and lows to the appropriate speakers for the best sound possible
