Small and Powerful

The newest JBL GTO EZ Series car audio amplifiers provide unmatched ease of installation, configuration and calibration for clean, powerful sound. Connect to OEM or aftermarket systems without complicated adapters or setup routines. Use line-level (RCA) signals or speaker-level signals with RCA-to-bare-wire adapters. Experience the clean and powerful output of GTO amplifiers in a variety of channel configurations and power ratings, all of which are CEA-2006A compliant and backed by the JBL reputation for top quality.

The full-range channels include a 40Hz to 220Hz variable crossover that's switchable for high-pass or low-pass operation (or bypass), and allows for precise tuning of the crossover frequency based on the speaker type and configuration being driven by those channels. Subwoofer amps and the subwoofer channels in system amplifiers feature a 40Hz to 280Hz low-pass crossover that lets you get the best blend between your system's subwoofer and the rest of its speakers.


The Sound of quality

Sonic Electronix, one of the leaders in car audio, recently visited Harman, the premium global audio and infotainment group, at their research and development locations in Northridge, California and Detroit, Michigan. The purpose of these visits was to utilize and combine the powerful brand of Harman and the industry leading knowledge behind Sonic Electronix to begin working together on developing future car audio projects.

Very Satisfied

This amp was combined with the factory stereo, 2 6x9, and 2 6-1/2" JBL's in a 2006 Impala. It sounds great and the tech guys were very helpful to me in choosing the right components!! I will definitely be back!!

Great Amp

This amp was exactly what I needed to handle my speakers up front. The compact size fit perfectly behind seat. Cd that comes with it makes it easy to setup.
