I am picking up my 05 1500 Hemi on tuesday.... Really Pumped... And i am thinking about the 10 inch infinity subwoofer for it (If it is possible). I found one from an SRT10 and really want to put it in. My truck has the infinity 6 speaker with 6 disc in dash. Does anyone know if it is possible to hook up the factory sub to the head unit or whatever and if so how??? Thanks
