Easy to give 5 stars for JMS/John: 1. Communication was direct, clear, and proactive throughout the process. 2. He offered helpful guidance to ensure I purchased the right system, along with just the right amount of supplementary equipment (had I followed Crutchfield's site recommendation I'd have ended up buying too much supplemental stuff). 3. Timely and professional for the install, and it was extremely convenient due to his ability to be mobile and come to my house for the work. 4. Old system was removed and new one in place in just over an hour, and it sounds great. HIGHLY recommended JMS/John to anyone looking for upgrade or replace their car's system. Will certainly use him again in the near future - thanks John! read more

Johnny is a sweet, kind man who really knows his stuff. I met him when he came to us to install a new car radio with a camera, and he knew all kinds of data about our specific car model that made the installation more successful. Later, after I'd had a surgery and could not lift more than 5 lbs., Johnny came over and helped me with everything from hanging curtain rods to recycling my Christmas tree. He always comes prepared with an astounding assortment of tools and armed with a smile, and it seems there is little to nothing he can't do! Thank you Johnny!! read more

I had JMS perform a full upgrade of my vehicle's audio system, along with the installation of a backup camera. The convenience of their mobile service made the entire experience incredibly smooth. They arrived on time, worked efficiently, and paid close attention to every detail. After the installation, they walked me through how everything worked, which I really appreciated. The quality of work, fair pricing, and overall professionalism exceeded my expectations. JMS clearly knows their craft -- I highly recommend their services. read more

We had a permanent lights installation done on our house. John started with a consultation and was up front about fees. He also made recommendations on our exact needs (but did not push more expensive products). On installation day he took his time and made sure it was done right. He also made sure we understood the installation as well as the product and how to control it. He clearly believes in and is proud of his work, and with great reason! We have already recommended his services to friends and family. read more

I requested a bid and information on putting a TV mount on the exterior of my home through vinyl siding. Johnny was very courteous and his communication was impeccable. he was very flexible his schedule and in the end after a long day of other jobs came out a day earlier than scheduled and completed the job despite running into issues. I was extremely happy and would highly recommend his services. I will no doubt be using him for future handyman jobs. I thought his price was reasonable. read more

Very professional workmanship. Appearance after project resembles a factory installation. traveled from O'Fallon Mo to O'Fallon IL to complete the job. Took the time to explain features of the audio product that I probably wouldn't have read in the manuals. Fee was compatible with the time and knowledge required to this job. Also hooked up the backup camera that is much needed item for us senior Jeep drivers. All in all, would recommend John to any friend. read more

i had a positive experience with John and JMS Utility Servoces LLC. He installed a Pioneer radio in my 2018 Toyota Tundra. Over text, he walked me through all the wiring harnesses and adapters to ensure a "stock" installation. i had no clue what to buy. Best part about John is the "customer education" he provided thru the process. He charged a fair price and the quality of his work was top notch! 10/10 in my book read more

I called John and originally had set an appointment up with him. I ended up getting a cheaper bid and John matched the competitors bid. Here's the best part.

Im a customer for life with John and will continue to promote his business to whomever may listen. read more

We requested assistance with our Govee Lights. They had been installed by another company a year ago and we had a strand that we could not get working.

I highly recommend him! read more

I contacted John to fix my cars blown speakers and he did not disappoint. I love that he was able to travel to me and get the job done while I was working. He was really thorough and explained all the issues and what was fixed. I'm really happy to have my car tuned back and the repair didn't break the bank either. Absolutely recommend! read more

John went above and beyond! He took time on his day to do research with me and make sure that we have the proper equipment. He worked with me on my schedule for him to install it. He stayed much later than he anticipated, but he was on the phone with Crutchfield trying to get all the settings, correct. Would recommend him to anybody! read more

Johnny installed Kenwood DNR1007XR in my 2015 Nissan Titan. He did an outstanding job. Very professional and truly knows what he's doing.
