I cannot say enough good things about Maximum Soundin Glendale. They provide excellent work and service in a timely manner. They installed a rearview mirror navigation, blue tooth and backup camera plus a remote start security system in three hours. Others said it would take seven hours. They have been in the audio business for many years and know their business. They have a very comfortable waiting room and there are located close to several food places. I recommend them very highly. Joan T.
