• Big audio output

  Big audio output

  Cars are small, and the space inside them is a challenge to audio engineers. But the GTO3501 gives you big, commanding sound. You’ll have 1500 watts of RMS at an impedance of 2 ohms and 1200 at 4 ohms.

• Variable electronic crossover

  Variable electronic crossover

  The GTO3501’s variable 12dB-per-octave electronic crossover allows you to optimize tuning based on your speaker location and specific components. And you can do it whether you’re a rocket scientist or not.

• JBL® Dynamic Bass Optimization Circuit

  JBL® Dynamic Bass Optimization Circuit

  Dynamic Bass Optimization (DBO) is a JBL® technology that lets you fine-tune your system’s bass output better than conventional bass-equalization circuits can. It includes a frequency control for the high-pass filter and a boost control that provides up to 12dB of bass boost.

• A pristine signal for great sound

  A pristine signal for great sound

  With a frequency response of 20Hz to 320Hz, the GTO3501 reproduces deep bass tones cleanly. Its full-range preamp outputs allow for multiple hookups without high-loss Y-adapters or signal splitters. Music reaches the amp and passes through it with clarity and fidelity.

• Remote bass-level control

  Remote bass-level control

  The GTO3501 includes a remote bass-level control connector for on-the-fly bass-output changes. Plug the optional remote level control into the connector, and you can adjust the level of bass as you drive.
