JBL GTO-504EZ 4.0 Car Wired Black audio amplifier

GTO-504EZ - 4 x 50W RMS (4 ohms, 14.4V DC, <1.0% THD), 4 x 75W RMS (2 ohms, 14.4V DC, <1.0% THD), 2 x 150W RMS (bridged at 4 ohms, 14.4V DC, <1.0% THD) It’s common knowledge that the performance of even the best automotive amplifier can only be as good as its installation and setup.

That’s why the new GTO line of amplifiers is designed to take the guesswork out of this process. Large, clearly marked knobs and color-coded LEDs, along with the included setup CD, make dialing in perfect sound easy. For upgrading a factory system, the GTO amplifiers make signal connection simple. No additional signal converters, adapters or plugs are necessary because everything is included in the box.

The complete line of GTO amplifiers includes chassis sizes, output-power capabilities and configurations sure to fit any car, any system and nearly any budget, and all are backed by the JBL® reputation for top quality.
