I recently upgraded my Ford Mustang with an amplifier and window tinting and the job was done in A+ fashion. I needed direction on stereo mounting vs amp needs and Ali/John were extremely electronically knowledgable to solve my needs. I was quite satisfied with all purchasers' criteria including selection, price and service. It was a great buying experience. Thanks again! WB

CSO is a wonderful place to get car stereo's and alarms. Ali (the owner) is easy to work with. Gives good advise and charges a fair price. You can always go back without any problems years after you have purchased something and he will always help you with any problem you may have. In a world of big business with changing employees without really personal service from someone who treats you like a friend, he is a welcomed change....highly recommended!!

very fair prices
