Do they seem like a good deal to replace my speakers?

Look like good speakers for the price and if you have a 3 speaker dash.
Some people put the little ones in the kick panels.

The magnet in the center speaker is pretty big and will hit the support brackets in the dash frame.So you'll have to do a bit of customising.
Could be troublesome.

I just bought this single cone off this web site. It fits perfect and works fine for my stock a.m.radio

The tri-coned will sound better if you have an am/fm or after market cd.
