The GTO24001 has been engineered to ensure optimum power delivery into numerous impedances with low distortion. It comes outfitted with a variable 12dB-per-octave electronic crossover, which allows optimal subwoofer tuning based on location and accompanying loudspeaker components. It also includes the JBL® Dynamic Bass Optimization Circuit, which provides variable filtering with adjustable Q below 100Hz. This circuit allows for tuning of any enclosure to any vehicle. Full-range preamp outputs are provided, facilitating multiple-amplifier hookups without the need for high-loss Y-adapters or signal splitters. The GTO24001 also includes a remote bass-level control for on-the-fly bass-output changes. The GTO24001 also features Direct-Connect, which allows use of up to 4-gauge power and ground cable to ensure enough juice is being delivered. Direct-Connect speaker terminals are also used, eliminating the need for additional adapters or special fittings. Common-dimension amplifier footprints are used on all GTO models, providing two common dimensions for ultraclean multiple-amplifier-model installations.
