I'm also wondering who makes the best 4" hands down? i installed an alpine head unit and i initially wanted to keep it consistent by hooking up alpine speakers, but if i could get a better sound out of it with another speaker manufacturer, then i would be pleased. I only have 2 mounts for 4" speakers and am considering adding a sub in back but would rather keep it simple. any advice? here are links to the only 4"speakers they carry http://www.alpine-usa.com/US-en/products/product.php?model=SPS-400〈=en&tab=Fhttp://www.kicker.com/ks_series

so what do you suggest? my head unit has a preamp but will i need a secondary amp? i want to have a nice system that sounds clear but delivers high levels of sound and decent bass(my car is pretty loud on the freeway and i want to drown the noise with music) and i want to keep it as simple as possible without sacrificing quality (i cant tune it up really high without the speakers sounding like crap)
