lol all the people in here telling you "it won't sound good" and its a power hog... probably have never used em and go by what everyone else on here has heard from one person or another so they repeat it.. They are decent amps if you know what you are buying.. They will do about 2400-2500 watts cleanly.. don't listen to the 2200 watts guy he has never used one I would bet.. don't crank the gains set it up right.. the MAX ratings are useless so don't base anything on them..
the one guy has a 1508d which is not the same so he bases his assumptions on that.. for a SUB amp unless you have some sq/sql subs you won't here a difference in amps especially at 2500 watts!! any one that begs to differ is retarded as at about 2500 watts you can get around 140+db depending on setup
