Amazing Bass In Very Little Space

It’s for anyone looking to add bump in the trunk. The GT5-1204BR has exceptional motor structure venting for serious thermal power handling. Patented Slipstream port design maximizes bass output and minimizes turbulence – no chuffing or whooshing, just a deep, car-rocking bass. Turn it on and up – a progressive spider reduces distortion even at high output levels.

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.
