What Client’s Say

Guys and girls for anything from simple speaker changes to reverse cameras and full sound systems pop in and see Waz and his team at Cairns Customs + Car Sound. Top guys, great quality work at an affordable price. Just had a new headunit put into my VY SS and I've got to say its perfect. I couldn't be happier. I will definitely be returning for any bits and pieces I need. Thanks again guys!

Mick McCarthyCustomer

These guys are awesome. They did a perfect job with my sound system and testing my air conditioning. Waz took the time to explain everything and give their advice where it was needed. All the staff were courteous, patient, and knowledgeable. They even gave me a follow up call to ensure I was happy with everything. I couldn't have asked for better service.
