I just had a compustar remote car starter installed. It by far surpasses my old one. The range is amazing and the other features are more than I expected. The install was quick and I’m super happy!

Extreme Audio knocked it out of the park with my new remote start! The team was professional, knowledgeable, and efficient throughout the entire process. They helped me choose the perfect Compustar Pro model for my vehicle, and the installation was seamless. I can’t express how convenient it is to start my car from inside my house or office during freezing mornings or sweltering afternoons – total game-changer! If you’re looking for top-quality products and expert service, I highly recommend Extreme Audio. They exceeded my expectations, and I couldn’t be happier!

Adam did a great job on my son's system in his late model Mercedes. Fair price. Very happy with Extreme Audio. Highly recommend them.

I went in to get my car audio installed I had two sundown 12 inch in a box with a 3200 watt amp. I talked to Adam and he assured me that it would be a 2 to 4 hour set up over the phone. i get there adam tells me they subs are great all working properly so after 4 hours I then asked what was going on I could hear the music playing and they told me they were testing it and it would be about 15 more minutes. Then 4 more hours passed I asked what was going on yet agian. They told me something was wrong and to come look I go look and my subwoofers both were completely blown. They said it was then my fault because I bought the subs box and amp off of market place but the real kicker is the seller tested them in front of me before I bought them after Adam telling me at the start of the installation they sounded great it was now blamed on me that they were both blown

Now to get out of paying for new sunwoofers they said only one was bad unplugged one so I couldn't hear the other subwoofer .

I could see a screw missing from a subwoofer

They then started shouting in front of my 2 year old daughter that it was not there problem.

9 and a half hours into the set up the owner showed up to then say it was my fault also .

Promised me a discount and gave me his word he would make them work .

10 and a half hours into this set up he then collected my money and told me he could not fix these $600 a piece and that it was my problem.

I at this time have been in the shop so long I just want all my money back

Took a phone call to my girlfriend on speaker phone to convince them to Give me a full refund

They did.

I then went home out of state with broken suboofers

Now present day other audio shops will not touch it because extreme audio has had that many bad reviews.

This team has been very professional and easy to work with. They have done a fabulous job tinting car windows for me as well as on my commercial property. The team at Extreme has also set our commercial office up with excellent sound and security services. I would not go anywhere else!

Kurt responded promptly and once on-site, he identified the issue with my business sound system. About an hour later, it's good as new!
