I tinted my 2012 Mazda 3 with charcoal 23% tint all around at audio heaven. It's safe to say theses guys know what their doing and all staff are knowledgeable to provide valuable reccomendations.
Not only are the employees friendly and professional but their attention to detail is superb! They actually do remove your door panels to apply the tint to ALL parts of your glass which adds to it's look and feel after installation.
I actually received a follow up call from audio heaven a week after my install which shows how much they put customer satisfaction on the forefront of their business model.
If your looking to tint your vehicle this is definitely the place to go.
