A FOUR MASTER installation is one carried out by one of our elite installers. These are independent businesses that have proved themselves capable of working to the highest standards. Utilising many years of experience working with all types of vehicle and with the best equipment, a FOUR MASTER provides a consistent level of pre and post sale care to those looking for a car audio upgrade.
Because of the high level of work completed, we are pleased to offer a five year warranty on a FOUR MASTER installation – whether a simple speaker upgrade or a complete system. This warranty offers national cover meaning any FOUR MASTER in the UK will honour the warranty on our behalf. Visit our Warranty Registration page for full terms and conditions.
Your FOUR MASTER will enter specific details of your installation onto our secure database. Information will not be shared with any third parties with the exception of Driving Sounds Magazine, with whom we have a working relationship. They will include you on a mail list to receive a monthly news bulletin. You may unsubscribe at any time.
