Scott, I Installed Speakers that barely fit into VIN 4606 rear firewall, but I don't recall the dimenstions offhand of how deep the speakers were. My advaice to you. Re-mount the rear panel that you drilled holes into and use a ruler to measure how deep on the hole a speaker can go. -Chris DMC6453 Scott <bk2d80s@xxxxxxxxx> wrote: So I am in the middle of replacing the rear speakers by mounting some 6" in the rear wall. I know many of you have already done this. Can anyone tell me what the maximum depth is on a speaker I will be able to get away with? I already destroyed my spare backwall by trying to mount in some 6x9s and they were too deep. They were like 3.5" deep. The new 6" speakers I bought are like 2-3/8 or so. . I can always get some infinitys that are only 2-1/16 deep but??? So before I destroy another backwall, does anyone have any suggestions to make this go smoothly? Yahoo!
