The JBL® GTO Series is one of car audio’s longest-running success stories – and offers the best-performance in its price class. The GTO8608C component system has a patented Plus One® woofer cone with up to 25% more surface area at work. A proprietary My-Ti™ tweeter gives increased power handling, reduced distortion. And a computer-optimized passive crossover with tweeter level control delivers improved response in any vehicle interior. With a peak power rating of 210 watts, the GTO8608C will add real muscle to any car audio system. Two patented, very easy mounting options make adding it a breeze.
