I am in a toss-up between the 165VB's and the 165V30's for my front component speakers. Will I be justified in the spending the extra money to buy the 165v30's? Also, the 165V30's are listed as 6 1/2" but are really 6 3/4" speakers, while my car fits 6 1/2"s. Will they fit in my car even though they are a 1/4" bigger?
