Sinewave — Local services in Grayslake

I was in search for a new car audio installation shop and was so glad to recently find Sinewave Car Stereo. Many of the places I knew of in the city had bad reviews and I knew of people having horrible experiences with, myself as well. I’m very particular when it comes to others working on my cars. I wanted to find a shop that had the experience, expertise and knowledge of this craft of car audio. From my first phone conversation with Joe I knew right away he was going to be the right decision. He checked all the right boxes and his in-depth knowledge of car audio equipment and advice was the deciding factor.

I had a new Kenwood eXcelon head unit installed in my VW GTI and the precision and craftsmanship he put into the install was above and beyond. I wanted to be involved and asked if I can see how he wired everything up before installing the unit in place. The way he took pride in his work with the harness prep to labeling the individual RCA cables was truly amazing. The end result is like OEM Plus factory fresh. He also double checked the rest of the aftermarket components of the system and fine tuned and fixed a few missed issues from other installers work in the past.

Joe’s passion for car audio and mobile electronics really shows in the quality his work. I just wish I knew of Sinewave Car Stereo earlier, this is the place to go to if you want it done correctly and professionally with a...

After purchasing a questionable headunit from eBay, I just could not finish installing it. I called around and no one was able to accommodate except for Joe. He talked me through the pros and cons of the unit I had purchased, and after discussing the possible risks of the stereo not working, I decided to go through with it. He made it possible so I could keep my original reverse camera, and keep the stereo working. I am so grateful! He is knowledgeable, fair in pricing, and a great place to go if you are considering any of the services he offers. I highly recommend if you are looking for a kind and trustworthy business to take care of your stereo and...

I was looking to switch out my stereo in my car to a Bluetooth one and Joe helped me out. He suggested I get one with a back up camera because of my tints and im definitely glad I did. He connected everything and now I can listen to music through Bluetooth or a USB cord and I have my back up camera which makes it 100× easier when I'm backing up at night. Not only that but he also did my under the seat lights and even installed my dash cam for me. Joe has been my go to guy for any upgrades I want to do with my car highly...
