I had a fantastic experience at Expert Electronics in Machesney Park, IL! My car stereo had gone out, and I needed a reliable replacement that matched my needs and expectations. Adam R. was an absolute delight to work with—he’s incredibly knowledgeable about all the products they carry. He really took the time to listen to what I was looking for, explained everything clearly, including the timeframe and the full procedure. No rushing, just great customer service! They were able to source the parts quickly and get my vehicle in and completed much faster than I expected. I’m super thrilled with the results—the new setup sounds amazing. Highly recommend Expert Electronics in Machesney Park for any auto audio or electronics needs. Tell John (the owner) and Adam I said hello—you won’t be disappointed! Thanks again for the excellent work.
Just had 12 inch subs and an amp installed in my son’s car. The staff at Expert Electronics were incredible. I especially want to thank Nick!!! He did the install and it’s fantastic!! He was very helpful and the install looks incredibly professional. I won’t have anyone else do my installs going forward. I’d highly recommend Expert Electronics for any of your car audio needs.
Very impressed with the whole experience. I called in regarding a stereo issue at noon and spoke with John. Was told to come in for a quick diagnosis later that day. The technician (who was a real cool dude) went above and beyond to check to see what was going on. Ended up replacing and upgrading my 12 year old subwoofers and amp with the G1's that were recommended. John was able to get me in next morning for install and I was able to drive away bumpin' again. Happy with the purchase and would recommend. I'll be back for a custom box someday. Thanks again!
Had issues with the Ford Police Interceptor integration for the remote start and keyless entry. But they figured it out and are getting me squared away. Solid place and great people working here.
