I've always heard Momos are just dressed up dxs that can handle a little more power, I hope you got some good subs, regardless $399 apiece you got hosed bad dude. You can get so much better online for far cheaper price, for example Eclipse 8812 alums, just over $300 at woofersetc.com, but regardless I hope they end up kicking ass, just think you payed way too much, but of course you've probably got a factory warranty, not flaming you, just think you should have shopped around and got a better deal.
