The JBL® GTO1004 is a great way to boost the power of your current car audio system. It’s a compact, 600-watt, four-channel, full-range amplifier with variable electronic crossover and bass boost. It’s engineered for optimum power delivery with low distortion. It has an aluminium heatsink for improved thermal performance. Its 10 Hz to 100 kHz frequency response is exceptionally wide. It comes with a 12 dB-per-octave electronic crossover that lets you optimise tuning based on speaker location and accompanying loudspeaker components. And its full-range preamp outputs enable multiple amplifier hookups without requiring you to use high-loss Y-adapters or signal splitters. Want more power? Just add a pair of JBL® GTO Series loudspeakers.

The JBL® GTO1004 full-range amplifier can wield a formidable 150 watts through each of its four channels. But don’t worry about all that power making anything overheat. The GTO1004 has an aluminum heatsink to keep the temperature under control.
The JBL® GTO1004 has a 12dB-per-octave electronic crossover – variable from 32Hz to 320Hz – that lets you optimize your car audio system’s tuning (based on the system’s components and their location). The transition from bass to higher frequencies is under your command.
For drivers who want to control the power of their car audio system’s lowest tones, the JBL® GTO1004 offers a bass-boost control. Adjust the bass by up to 6dB – or leave it alone. The power is all yours.
An amplifier is meant to connect to other components, and the JBL® GTO1004’s high-quality, Direct-Connect terminals provide connections that you can trust. Its full-range preamp outputs permit multiple hookups without requiring high-loss Y-adapters or signal splitters.
The JBL® GTO1004’s 10Hz to 100kHz frequency response stretches above, through and below the range of human hearing to capture everything that your audio sources offer. From symphonies to rap, there’s no sound that the GTO1004 can’t handle.
