This is part of my 2010 Prius' original invoice info: 8 speakers. The bass is enough to numb your skin from your hair vibrating. Isn't there a subwoofer installed? If so, where is it? Trying to remember though... if there is 1 each front door, 2 in dash, 2 in each back That is 8. The stock stereo is pretty killer, but I am guessing there is no subwoofer?
