Factory Speaker Cut-out Dimensions
 

I am interested in anyone that has a late 90's Fountain with the factory Kenwood 6.5' in it . . .what are the size of the cut-outs for the speakers? I am going to replace all of my speakers but need to know if I am in for a throw 'em in and go or a major undertaking with a Rotozip .. . . . and my boat is 230 miles away . . . .
