I think so .. Their 92db spl. which is pretty efficient.. The front/doors for sure now it's a clearer sound not muddled.. I have a iPhone and use a FM modulator thru the antenna that plugs into the phone for sound and charges too. The volume is lower than it should be kinda like line level, but I can go full volume on the factory unit and still sounds good

Like I said for now it's fine, but may get a head unit in the future
