That is a lot more reasonable.
I have been looking at a number of speakers online. Many of them are called 'woofers' plus the coaxial tweeter, usually 4 ohm.
I doubt they add much bass compared to the door speakers and I might want to add a bass blocker anyway. Plus I wonder if the edge is sealed around the speaker. They might be my best choice.
Parts Express has some 3.5 full range or midrange but I don't know if they fit the space properly.
I know there is a huge advantage to having speakers on the dash for the sonic imaging etc plus I just dont get much treble from the front. In fact I was listening carefully and I heard more treble from the rears! So even crappy are probably better than none.
