This has probably been asked a million times, but after a 20-min search through the forums and several websites conflicting information, I am still stumped as to what precisely the size of the speakers are in my 1991 Accord SE. My questions are as follows:

1) What are the exact sizes of the front and rear speakers?
2) What are the exact mounting depths for the front and rear speakers?
3) I have heard the fronts are 5", an unusual size that I am having trouble finding to buy. Would the mounting bracket hold a 5-1/4" speaker? Does anyone perhaps have a link to a quality replacement 5" speaker (hopefully component)?

Thank you.
