Will go for d8604 then, as far as the speakers are concerned, i want them to be as concert-type loud as possible with no excessive bang, as a result when i play tracks on this setup it go crystal clear throughout the track due to speakers and when the beat drops the sub comes into play as giving it a balanced feel, another condition is that the speakers must overcome or go head to head with the sub instead of getting eaten raw by the sub. Now give your opinion on the speakers(if possible pioneers). Also state where to get it from and where to get it installed from? Any positive feedback would be of immense assist.
