Upgraded Stereo System in a 2003 BMW 325i

The owner of this 2003 BMW 325i wanted to upgrade his Stereo System. The first thing on the list was to upgrade the factory radio with a JVC car stereo model KD-AR855BT Bluetooth CD receiver.  This is a good head unit to power a car audio system and also provides Bluetooth hands free calling. To properly power the subwoofers we added a Kenwood amp model number X500-1. For bass we installed two Kenwood KFC-XW10 10 inch subwoofers in a dual slot ported box. On top of that we needed to get some security on this BMW to protect the new car audio equipment with a Viper 3105V car alarm. Professional installation of this upgraded stereo system done by the tech crew at Quality Auto Sound 6699 Leetsdale Drive, Denver, CO 80224 303-394-3500 your car audio installation experts. We can recommend and install an upgraded stereo system to fit your car and budget.
