What is Fourmasters?
AN ELITE INSTALLER NETWORK
Fourmasters Car Audio is a national network connecting drivers who want better sound in their vehicles with a curated group of specialist installers capable of delivering it. Membership is not open to everyone — installers must demonstrate the technical knowledge, installation quality and customer service standards that Fourmasters demands.
As a Fourmasters approved installer, Audio Division has been vetted and certified to install Audison and Hertz products to the programme's exacting standards. That approval means you can book with confidence — you're not taking a chance on an unknown workshop.
The network exists to make car audio upgrades easy. Clear advice, accurate quotes before you commit, and ongoing aftersales support if anything ever needs attention.

PRODUCT WARRANTY
5-year product warranty
COVERED FOR FIVE YEARS
Every product installed by a Fourmasters approved installer is covered by a unique five-year product warranty. That's five years of protection on your Audison and Hertz equipment — not the standard one or two years you'd get elsewhere. It's one of the most compelling reasons to choose a Fourmasters installer over a general retailer or independent fitter.
