First of all let me say I have never seen a car have issues with radio speakers like this platform. If fact in my 40 years of driving I have never had a speaker just stop working all together like these cheap mexican GM speakers. The question is are the back speakers the exact same speaker as the fronts other than the front looks to have a separate tweeter. 2008 Ascender stock radio , non bose . I got the backs working one was blown back there and now I notice the driver front speaker doesnt work other than the tweeter part. I have one from back the which is fairly new that the dealer replaced but I took it out when I replaced the back two with new Kenwoods do to a blown driver rear speaker . If they are the exact same speaker I may just replace the blown one with the working one from the back for now , or are they different ?
