Trying to get some feedback on some speakers I'm thinking of getting put into my Jeep. I want to go with Diamond Audio M6661's in the front to replace the 6x9's in the doors and the tweeters in the dash, and also M361i's to replace the rear door speakers all being run off of a Tsunami 4440. I've only seen people commenting on the hex's but not on the M series. Mainly trying to get an idea if these are decent speakers and where they fall in on the quality speaker foodchain and they rate up there with. Thanks for any replies.
