Best place for tweeters in a Yaris HB (imaging)

[beto2]

Hi, I've been looking all over the forum looking for a guide to install components in the 2007 Yaris HB but have had no luck. I might even get a 3 way component set Focal 165a3 but would like to know if its viable and where could I Install the mids and highs (front doors).

So where should the tweeters go? where should the mids go? how can I install the mids since there is no oem space for the mids?

I might just go for a 2-way but still I don't know where is the sweet spot for the tweeters in order to have the best imaging (or staging).
