hey bro, i took my back seats out about 4 months ago to do the same thing. well, never happend. the only thing that sux is the road noise, and the fuel pump noise when the radio is at low volume.
other than that, i never liked puttin peeps in my backseat, it is way too small to start with, and i think it is just an insurance gimmick.
