so your sayin only kicks and subs, no rears? (from article in un4givin's post)

Yes. Maybe this will help.

quess i am gonna sell my 6x9s and 4x6s and get me kicks, so what is the best components...infinity kappa? do they carry enough bass?

That's really a personnal preference. I have Infinity's in my car and I like them but Infinity's don't have as much mid-bass as I like. But what' s right for me might not be right for you. The best thing is to shop around and listen to what's out there and pick the ones that are in your price range and provide the sound you like.

thanx

Only kick speakers?? Your suppose to keep your rears. Don't loose those ones. Just move your up fronts to kicks.

i thought the right rear will over power all the other ones

As you can see in the pic I posted above the imaging of the rear sucks big time. The Driver only hears the right rear and the Passenger only hears the left rear. Therefore throwing the imaging out of wack. The only need one would have for rear speakers is for passengers sitting back there to be able to hear the music besides just the bass.
