i'm about to buy a 95 plymouth neon but i need to change the mains out. i want to put MTX mains in as the replacements, the only problem is size. i can switch the 6x9s in the rear but the fronts are 6 3/4s and i can only find 6.5s in MTX. would the 6.5s be able to fit in the 6 3/4s hole? any help would be appreciated. thanks.
