JBL GT-BassPro12

The JBL GT-BassPro12 powered subwoofer pumps out lush^ car-rocking bass through a design so cool you wont want to hide it in your trunk. The patented Slipstream port design delivers deep bottom end while minimizing turbulence. Turbulence^ or port noise at high volume^ isnt just annoying; its a signal that the port is no longer working and youre getting less bass than you paid for. The Slipstream design is carefully optimised for the combination of woofer^ amp and enclosure^ and no other company has it. And with the included remote control for drive-time adjustments^ the only time youll need to stop is for gas.
