These customers came in with their 2014 Nissan Sentra. They wanted a car stereo and bass system installed. When we showed the customers our options on display, they fell in love with the Kenwood Excelon DDX492. They like the fact it has a volume nob control to adjust the volume, HD radio and Bluetooth streaming. For the bass, the customers went with the all-in-one bass package JBL GT-BASSPRO12 that comes with an amp, bass nob, and subwoofer enclosure. With the combination of the stereo and bass in the car the system sounds awesome! This Nissan Sentra subwoofer and receiver were professionally installed by the tech crew at Audio Express 4501 E.
