I have the least amount of knowledge when it comes to car audio systems, and that is why I have to ask you the following 4 questions. I would GREATLY appreciate any answers.  
	1) I just want to replace the speakers with better ones as I don’t want to drill holes in the door panel for tweeters. Does that mean that I have to buy “coaxial” speakers, instead of “component” speakers?   
	2)Assume that the price for the following 4 brands are the same . What brand would you choose? 
	MB Quart, Polk Audio, Alpine, JBL  
	3) Whichever brand you just chose from above, can you please recommend your model preference?  
	MB Quart - Discus 2-Way Car Speakers with Mica-Filled Poly Cones  
	MB QUART - X-Line Coaxial Speaker with Polypropylene Cone  
	MB QUART - Z-Line 2-Way Speaker System with Polypropylene Cones   
	Alpine - 2-Way Coaxial Car Speakers with Poly-Mica Cones  
	Alpine - 2-Way Coaxial Car Speakers with Polypropylene Cones   
	JBL – 2-way Component Car Speakers with Polypropylene Cones  
	JBL - 2-Way Coaxial Car Speakers with Polypropylene Cones   
	Polk Audio - MM1 Series 2-Way Car Speakers with Dynamic Balance Cones – component 
	Polk Audio - MM1 Series 2-Way Car Speakers with Dynamic Balance Cones-coaxial   
	4) In general do you prefer Poly-Mica Cones over Polypropylene products?  
	Thanks in advance for assistance.
