Well I just reread this WHOLE thing again to try to understand it better!! which is helpful to slow it down. From what I got you guys say dont replace my rear speakers at all just keep the stock ones there?

Ok so then I just need to raplace the front speakers and possibly the one center speaker on my dash? and the HU? If so that makes things alot easier as I reduced the cost at looking for a rear speaker that would be around $80.

Ive heard talk of a good component system for the door setup. So lets say I go with compentent for the door stay with the stock rear speakers. Lets get a setup that way.

Still unsure what to do with the center speaker on my Dash.
