Hi, i'm looking for some good quality speakers, i need a total of 4..i don't really want to spend a whole lot of money..but it isn't the worst thing in the world

its for my truck, a 2001 Chevy Silverado 2wd the sizes are 6.5 in the front doors and 4x6 in the rear

sorry if this is in the wrong forum, i thought it might be right..
