thats a great choice!Right now I have 2 12" Type R's on my Mrp-M1000. So I want to use my M1000 for awhile at least until I have the money for an amp that will do around 4k rms but I want to get the subs so I want to get subs that will handle a little more than 2 k a piece so I was thinking since I am keeping my amp I will have more money to spend on subs so I think i'm going to do 2 15" DC level 4 XL's
