Joe was absolutely fantastic! He took time out of his Monday afternoon to come troubleshoot an issue with our boatβs head unit and amplifier. He quickly diagnosed the problem, got everything working, and explained what was going on along the way. What really stood out was how generous he was with his time and knowledge. He was patient, professional, and clearly knows his stuff. Itβs rare to find someone whoβs not only incredibly skilled but also genuinely enjoys helping people. If youβre looking for someone who knows marine audio systems, I canβt recommend Joe highly enough. Thank you again for saving us a lot more frustration and getting us back on the water with great sound!

We got a full audio upgrade with Cicada on our Harley. It's crystal clear and loud now, we can hear while riding. Joe is very knowledgeable on the products and needs for the specifics. Highly Recommend for all your audio, camera systems, remote starts and much more. He takes the time to make sure you will be 100% satisfied. He's your man! Give him a call you won't be disappointed.

I had an excellent experience with Joe and Sinewave today. He removed a remote start system for me. From initial contact through completion of service, the communication was prompt, knowledgeable, and friendly. I highly recommend this place and will return for any future needs.

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. Iβm 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. Joeβs

I have had Joe install full stereo systems in all of my vehicles including my motorcycle! Also has done remote starts on several of my vehicles and his work has always been top notch! Forgot to add that he also did an excellent job on the security camera system in my shop!Would definitely recommend!!
