I have been told but don't know for sure yet, that the front and rear door speakers are all the same. Now that I have the intermittent no crank problem fixed, I am now focusing on the speakers problems. The only speaker that works is the driver's rear door speaker. Because I still need to do a side to side swap to see if the problem is the head unit or 3 bad speakers, I am reaching out now to see if a member here has any speakers for sale. If I find that the speakers are the problem, I would want to buy 4 speakers, in case the one working speaker is on it's way out. Thanks for any help with this and please respond with info on whether the 4 speakers are in fact all the same.
