The motorsports segment of audio products has several unique challenges to overcome. GSF have designed custom solutions to create high output drivers and systems to overcome the inherent noise from a motorcycle or offroad vehicle.

Additionally we utilise materials and technology to ensure high weather, vibration and shock resistance to ensure our solutions keep the audio playing no matter how hard or fast you go off road.
