If I understand correctly, the stock 5-1/4" round soundbar speakers can be replaced with 6-1/2" round speakers with no modifications. What about the fronts? What will fit with no mods, what fits with mods? Any good links on modifying the fronts? ( I googled but didn't get any leads.) This is for an '02 TJ Sport - stock bottom end (cassette head) system.
