Hey guys, so over the weekend I took the family to the Buena Park location and did a test drive on a MS & MX I'm about 2 weeks or so away from getting my 2013 MS CPO w/ the upgraded sound. While I was at the dealer I got to listen to a standard system and the upgraded system, my conclusion is that they are both decent, obliviously the upgrade is slightly better but I still think its missing that lower end (bass) sound. I'm really considering getting the NVX sub kit, but I really would like to hear the setup 1st before I purchase, so I come to the "club" to see if anyone around the SoCal area has it installed and would be willing to meet up for me to listen to it!!! I live in the I.E. but work near Cerritos, so anywhere around those areas would be great!!!! Of course a coffee/beer/cocktail or whatever would be on me for your time. T.I.A.
