Woofer Electronics, Chicago

You can learn a lot in 20 years. Woofer Sounds certainly has—since it first opened in 1990, the business has expanded to become one of the largest sellers of mobile electronics in the region. A team of knowledgeable technicians is on hand to answer any questions about their selection of sound systems, accessories, and video systems, from brands such as Alpine and Kenwood. The experts can then equip autos with accessories ranging from GPS navigation systems to rear cameras that keep an eye out for pranksters taping "Rent Me" signs to back bumpers.
