what to buy?

I'm basically getting a whole new sound system except I already have a head unit, capacitor and 2nd battery. The problem is ,as usual, I'm having a problem making up my mind. For door speakers (6.5 components) and rear speakers (6X9s) I'm considering either alpine type-Rs with an alpine amp or Polk audio momos with a Polk amp. Both setups will cost me about the same, but i think the momos retail for more.I'm also looking to get 2 12" or 15" subs and i'm looking for loud bass but with decent SQ. I'm also trying to decide between alpine type-x or orion h2 subs. A few people have told me that the h2s are very loud and have good sq but the type-xs are high wattage and look to be good subs also. I have a hifonics Brutus 1500D amp but I'm considering buying a new amp unless this one will be good for the setup I use, I'm not determined to get either alpine or orion, any good sub will do. Any response will be greatly appreciated!
