A friend of mine currently has an all Memphis setup consisiting of 2 15" M3's ( Not Mojo's) and a PR1000D. He's considering selling his whole system ( highs amp too) and going for a something that sounds good, SQ and still gets loud SPL. Suggestions would be appreciated. He'd like to stick with 2 15's but if he can get good sound quality and still be loud with just 1 thats fine too. Oh and the budget is about $1000 or so.
