Hi all. I know this has been covered many times but just wanted to get your thoughts. I just got off the phone with crutchfield who has sold me a set of kicker front door woofer and tweeters, and rear door speakers. These are 4ohm speakers. They said they are totally sure these will work without straining the system amp. They said the amp is 4ohm stable. They said the speakers would just be a little louder. I wanted to got that route rather then refoaming but now I am not sure if I should keep these or not and just refoam. I know the rear sub is 12 ohm, and the midrange door speakers they do not have are 8 ohm so the speaker ohms are kinda all over the place. What say you mud?
