High-performance subwoofer power for enhanced sound on the move.

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.

The GTO-751EZ Class D mono subwoofer amplifier is rated to deliver 750 watts RMS at 2 ohms (1200 watts max). High-efficiency Class D amplifier design ensures the most boom for the buck, all in a modestly sized chassis. It’s an impressive amount of power in an attractive, easily configured amplifier. The wide input range and low current draw make the amplifier ideal for adding a subwoofer to existing OEM or aftermarket systems.
The GTO-751EZ subwoofer amplifier includes an input-level switch, a setup CD with test signals and LED indicators to tell you when the setting is correct. Simply set the switch, turn the input-level knob and watch for the green light that indicates that the setup is perfect. That’s all there is to it. There’s a reason why the amplifier’s model number contains EZ. This feature significantly reduces installation time and delivers excellent results.
JBL engineers have configured the GTO-751EZ amplifier to turn on with a wired input (as in aftermarket systems) or with an auto-sensing circuit that activates whenever the amp detects an audio signal. The auto-sensing feature is helpful when you’re upgrading OEM audio systems that don’t include a remote trigger wire. It’s easily defeated by a switch when you’re using a wired remote turn-on input.
The GTO-751EZ amplifier accepts a wide range of inputs up to 15 volts with line-level or speaker-level signals. Using RCA-to-bare-wire adapters included with the amplifier, you can connect to virtually any OEM or aftermarket audio system. The end result is an amplifier that works with the widest range of cars on the road.
An active 12-decibel/octave low-pass crossover offers variable filter points between 40Hz and 280Hz. Importantly, all filter points on the adjustment dial match the silkscreened frequency points on the amplifier chassis – a feature that not all amps provide.
The GTO-751EZ provides a range of bass boost from 0 decibels to +12 decibels, centred at 45Hz. This is a useful feature for restoring some bass that may be limited by the low-frequency response of certain speakers in the system – or to enhance a particular range of bass that the speakers already produce well.
The high-efficiency, low-current and low-heat performance of Class D amplification ensures high power output from the GTO-751EZ subwoofer amplifier. It also minimizes any need for upgrades to your vehicle’s electrical system.
Amplifier protection is just like insurance; you hope you’ll never need it, but it’s sure nice to have it when you do. Thermal protection keeps the GTO-751EZ amplifier from overworking itself to the point of premature failure. Low-impedance protection keeps the amplifier safe from any speaker or wiring failures that result in short circuits.
The GTO-751EZ amplifier is compatible with the optional wired-remote bass control, which provides easy adjustment of subwoofer-channel bass levels from the front seat. The wired remote is easy to connect with a telephone-style jack and can be mounted in a variety of positions to suit the vehicle and location preferences.
