6x9's Fit into 6x8 Holes..? How Hard is it..?

My tbirds has stock 6x8 holes, how hard is it to fit 6x9's into them..? The depth clearence is no problem, but what should be done..? How would you enlarge the hole..?

you could use a die grinder, dremel tool, jig saw...Alot of stuff would work, depends on what the material is made out of though. I don't think it would be to hard to do

no, it's not that hard, my friend fit a 6X9 in a 6.5 hole once.

you might be better off putting 6 1/2's in there

hehe, my 6x9 hole is now a 6.5x6x9 hole with a sealed baffle....
