3 1/2 years of first place wins since I started competing in SPL....I change my system up on a regular basis...I run different combinations of amps and subs....so I don't run the same setup over and over....I do all my builds in street driven vehicles...I could build a strictly SPL trailor vehicle...I have a nice caravan just for that if I decide on it.....But right now I'm into street vehicles.....Here is a pic of my Van....There is work being done on it as well.....as we speak...in case I decide to do a build in the near future...
