Pioneers all around, in both Contours I've had... cheap and decent sound.
Now when I decide to shell out a little $ for a nice 4 channel amp, I'm gonna get components.
Also I've got a 1999 series RF punch 15" in my trunk... can handle a whole 150w RMS at it's 8ohm resistance. Getting about 90w RMS or so right now and sounds just fine for me and my rock music.
