Will kickpanel speakers from brothers sound ok?

[72farmer]

I need some ideas on speakers for my 67.I just installed a Old Air system in my truck and now i do not know what to do on speakers.I bought a set of Sony 5X7's from walmart and was thinking of making a bracket to mount both of them side by side and put them in the original speaker location in dash.I was looking at the kickpanels with 100 watt Pioneer speakers on sale at Brothers for $199 -15%.Which would sound the best?
