Would anyone recommend pioneer? It seems to me that they can handle
quite a lot of power. any comments?

I mickey moused my Pioneer 300 6x9s under 6.5 holes. This causes them
to pick up noise. I will be replacing them probably with Infinity
Kappa 63.5i components.

The only reason I am replacing the speakers is to cut down on having
to nibble my speaker holes, and to eliminate the noise. As far as the
speakers themselves, I've blasted them at insane levels, and they
still hold up well (I power them with a used Jensen 400w 4ch amp).
They are nice and clear, not muddy, give good bass and mid, and the
highs aren't too bright. Well balanced. I got my pair for 75 bucks.
They've been through hell and back, and they sound awesome regardless.
I'll probably install them in my sister's car, or sell them off for
like 20 bucks... either way, I love these speakers, and I would
recommend them to anyone who wants good affordable 6x9s, especially
the 300's.
