They spent two hours on the phone with me on a Sunday evening past their closing time helping me resolve installation issues with the system we bought from them for my son's 2003 Jeep Liberty. First no sound, found in door amps were not hooked up to new system harness. Second issue steering wheel control interface would not program per instructions. Tech was online and on the phone with me at the same time sending me e-mail alternate instructions until we came across one that worked. Every system I've bought I've bought from them and will do in the future.
