I found the bose sub was junk, my ghetto blaster from the 80's can put out more base then that. So while installing my nitrous bottle i noticed i would have to take the spare tire and sub out....today i went out and bought 2x 10" rockford fosgate subs and a 1200 4 way audio amp...got all the wiring kit and also a compustart alarm and remote starter for $1038.
