I recently upgraded my sound system because one of my rear speakers wasn't working. So I'm selling the other functional one. It is only one piece. Completely functional. My vios is 2004 G series. I was looking for someone to sell this item so that I can put back my original speakers but no one was selling. Anyways, now I'm selling this. So if you are like me you can have this for RM 100. Please note that this is 12 watt so if your car electric system is different you better consult a car wiring expert first.
