Hello all I have a question. I have a 2004 Envoy XL and I'm looking to add a set of 6.5 speakers behind the 3rd row seat (so the kids back there will stop saying "turn it up I can't hear it") somewhere possible on the lifegate or pillars preferably and wanted to know if anybody has done this and if so would you have any pictures and or advice on what speaker pods etc etc worked best. If this has been covered already I apologize as I haven't found a thread for it.
