307 FRONT AND REAR DOOR SPEAKER SELECTION

& nbsp;

Yesterday, I joined the 2006 Model & nbsp; Peugeot 307 1.6 HDI 110 HP vehicle. I haven't done the wrong part of introducing myself. & Nbsp; The posts are really nice in the forum. I wanted to ask you a question that got stuck in my head. How many cm are the front and rear speaker sizes and there is a speaker on the back right because I don't hear sound from my rear right speaker, or I think it is broken.
