I am interested in purchasing new 4*6 speakers and 6*9 speakers. I dont want to run my 4*6 speakers by an amp but later on in the summer months I wud like to put an amp on the 6*9 speakers. I was thinkg of going with either Alpine or Polk Audio, because i have herd them both and thought they where good. Basically I was jus hoping you guys cud help me make a decision or turn me on to another brand of speakers that are good. Thanx
