there is a black f150 ext cab at buzz off with 6 15" rockfords in it and the back cut out the cab and all the amps in the bed. also the polk truck stopped at CC one day and had 4 12" polk momos in it and it fuckin slammed!! There is so much u can do wit a f150 and the small cab makes it even louder. Thats why when i had 2 10's in my old s10 it sounded damn loud
