I need the 3 1/2's for the front, and what is it 8 1/2X3 for the back ( I cant remember) for my 87 monte. My 22 yr olds speakers finally gave out. I'm not looking for anything fancy, just a good solid replacement. I bought some rampeage speakers 5 yrs ago for my other 87 monte and they didn't last long. What do you all recommend?
