They are very good at doing a quality installation and there car stereo equipment is great and reliable

Ultimate Concepts does not only sell the best remote car stater system, they also stand behind their products. We had an issue with our remotes not working and they took care of the issue quickly. Come to find out, the reason the remotes quit sending the signal could have happened when I replaced the battery in the vehicle. Either way , Jerry was so helpful and courteous during our time trying to get them working. I will not go anywhere else when it comes to their sales and service. read more

So I am not sure who wrote the other review here on yelp but I could not disagree more. Steve and Jerry have been doing work for me since the early 2000's and I have never had a bad experience. One of the things I like the most is the customer service they will never try to upsell you on products or services. They will listen to what you want and do everything possible to get you what you want. Just like with anything else in life you get what you pay for. There may be other shops that are cheaper but the service and products you get are not worth the little bit of cost savings. After having them work on more than 10 cars for me and a boat I would not trust anyone else to work on my vehicles. Chris read more

Ultimate Mobile Concepts is the PLACE to go for car stereo in the Cedar Rapids area. The owner, Steve, carries some great lines such as: Alpine, Kenwood, JL Audio, and more. He is EXTREMELY knowledgeable in both car stereo, car security systems, and remote starts. Steve has worked on no less than six of my vehicle audio installs. I don't have a single complaint. read more

Had my 2008 GMC Envoy fitted with a 12" sub after I installed my stereo, $100 buck, to install amp and Sub and run wires, Did a great job on it very professional! read more

Steve and Jerry are always very helpful and carry great products. I've been going to Steve for almost 20 years.

Ultimate Mobile Concepts is a small, specialized, generally high-end shop for automotive audio and security systems. They are truly experts in their field, whether in recommending systems for a specific vehicle or making challenging installations. They are extremely helpful, and their prices are reasonable, when compared with equipment of like quality. I KNOW what bad service on mobile systems is, and, as a result, Ultimate Mobile Concepts are the only people who work on these systems for my vehicles. I can recommend them with no reservations or hesitation whatsoever. They are real professionals, and the best in the region. I know there's a bad review on Yelp. It is completely contrary to my long-term experience with this company, and I think you should ignore the sour grapes. If you bring your own food to a restaurant and ask them to cook it for you, you'll likely be met with some disdain. Same thing with bringing your own parts to an automotive installer. I'd be cranky with such a customer too. The profit is in sales, not installation, and these folks are in business to provide their customers with the finest equipment available in a given price range--and they know what they are talking about. read more

The owner of the place was very help-full with the products they carried and did a great job working on my system. However was very rude whenever any questions were asked or products were purchased that were not from his business. I had older equipment i wanted installed by them professionally and he was not shy in his feelings nor would he answer any questions or best practices. He flat out stated that unless you buy from him, he has no opinions and would not talk to you. I thought this was strange since I was still wanting to pay for his professional install services. Which I clearly could go to any Audio dealer in town to have completed. My recommendation is to stay clear unless you plan on buying his equipment and following exactly what he wants you to buy and install. Otherwise he is quite rude and really not customer friendly. However, the work he provided was still good i would never go back. I would rather pay twice as much someplace else and receive better service without the attitude. read more
