Testimonials

Best Experience!

I went into Area 41 today to upgrade my subs and the salesman spent a long time with me and didn't rush me I really appreciate that I was able to listen to different systems in different cars. I was able to get a whole system that is a lot better than just getting the subs I came in to ask about thank you

I Love This Place!

I love this place! Very knowledgeable staff and they installed one 12 that sounds like 2 for cheap. They also took the time to make sure that the car looks like it does before the installation so you can't even tell anything was touched. If you want awesome car audio come here!

Awesome Staff

Awesome staff and very precise with details. Long wait but they have a comfortable atmosphere and make you feel at home so the wait wasn't bad at all. Will be taking my other car for them next week. I highly recommend them!
