What's the 2011 Chevy Impala speaker size?

The stock speakers in a 2011 Chevy Impala are 6-¾ in the front doors and 6x9 in the rear deck. Most Audio packages also include a pair of 1 tweeters mounted in the front pillars and a set of 3-½ inch tweeters in the rear deck. To replace the stock speakers You will need to remove the front door panels as well as the rear deck covering. Most people chose to replace the stock 6-¾ speakers with 6-½ since they are more common and are offered in a much wider range of prices. The rears will usually stay at 6x9 since that format offers some pretty big sound advantages over the smaller round formats. To remove the back cover You will need to remove the surrounding panels as well as the rear seats.
