Since 2005 we at Four UK Ltd have worked tirelessly to hunt down and promote specialist car audio brands we believe encapsulate our demands for excellent performance, reliability and value for money. As such we have introduced unknown brands and turned them into market-leaders, promoting them in a sustainable way ensuring that rather than a flash-in-the-pan, our brands offer longevity and consistency to the market place. All of our products are subject to a rigorous process of evaluation, which is why we are confident to declare ourselves "market leaders" in high quality car audio products to suit all pockets.
