About us

In Phase has been trading since 1989 specialising in the supply and installation of many esoteric car audio brands, however we always had many challenges with the ever changing quality of the products we supplied and installed. As a reseller we had no input or control over the design and performance of the products, which we knew needed to be improved.  

Our years in installation knowledge gave us the edge in understanding what the products we supplied and installed needed to do and where they needed improving, so we decided the best thing for us to do was to make our own products. Designing and producing our own products made sense as we knew the products would be right and give our customers real performance and value. In 1995 we launched our first products, it wasn’t long before In Phase brand was starting to be recognised in the UK for our quality and performance.  

We slowly expanded the range and launch our signature XTC/SXT speakers and our IPA amplifier ranges. We have produced some of the best subwoofer enclosures in the world known as the XTB series, these produced unbelievable amounts of bass with such dept and clarity. Today we offer a full range of products that complement each other.  

Still a family business all staff and owners are proud to be British. Being British gives us the edge over many brands as we develop all our products to give the performance we expect (us Brit’s have high standards). Now the world can enjoy the benefits and In Phase is sold in many other countries worldwide. 

The team has grown from our humble beginnings, now employing over 30 staff with more than 500 years of audio experience between us! Still hands on product development and testing we are constantly improving each of our products to ensure on going performance. We are proud of our products and hope you enjoy them as much as we do.
