The JBL GTO-1514 is a 15-inch single-voice-coil car subwoofer from the Grand Touring series, designed to add deep and impactful bass to your vehicle's audio system. It delivers a nominal power of 350 W RMS and can handle peaks up to 1400 W, operating across a frequency range of 23 Hz to 400 Hz. With a sensitivity of 93 dB, it ensures that low frequencies remain clear and powerful even when competing with ambient road noise. Its construction features a polypropylene cone that provides necessary rigidity and weather-resistance, paired with a flexible rubber surround for consistent movement. The structure is supported by a proprietary die-cast aluminum frame which offers the strength needed to hold the motor securely in place. To maintain reliability during extended periods of high-volume playback, the motor includes vented polepieces that help dissipate heat. For installation, the unit requires a mounting cutout diameter of 354 mm and a depth of 172 mm, fitting within an overall external diameter of 389 mm.
