Ampere Audio AA-6.5sc Coaxial 6.5" Car Speakers

I own some Ampere Audio 8 inch subs, and they are little beasts. Because of this, i bought a pair of the Ampere Audio 6.5 inch coaxial speakers for my rear doors. Although they handle low mids and bass significantly better that the Kicker Coaxials that i replaced them with, they sound very dull, no depth, and no definition like other speakers. However, Showtime's customer service and delivery was on point, great, and awesome.
