Pioneer? Kenwood? Infinity? Help Me Out!

I am trying to decide what kind of 6x8" speakers to get put into my 1998 Ford F-150.  I had my heart set on the Infinity Kappas, but I wanted to see if I could get about the same performance for the same price range.  I was thinking maybe Pioneer or Kenwood speakers?

Pioneer - I have a Pioneer headunit, and it might be nice to try and keep 1 - 2 brands only in my truck.

Any other brands that anyone recommends?

Anyone please let me know!

I wrote a nice lil reply earlier this morning but the site kinda had a heart attack on me when I finally pressed "post" and I wasn't sure if it got sent.  I left to go to work and now I'm back and looks like it never got sent, oh well!

ANYWAYS, I was going to suggest that you go with the kappas--they're very good speakers and are a very good value for the SQ that you get.  Focals are amazing but they can get kinda expensive sometimes; for some people it's worth that extra money, but for a lot of people they're just too expensive.  That's kinda something you'd have to decide for yourself obviously....

I've heard the new Pioneer REV speakers are awesome but I've never heard them myself so I can't verify that.

Might wanna try doing a side-by-side listening test to compare some different brands and models, if that's possible.  If you have to choose blindly though stick to the kappas.

Kappa's man.

I have them in my car (along with Kappa 6.5 Components and 2 12" Kappa Subs) and they sound awesome.

Kappas it is.  I can get them for about 70 a piece too through my wholesale dealer.  Thanks all for the advice.

About the Crystals and Focals, I'm just not a big fan of change.  Its hard for me to trust a brand if I haven't heard it in realtime action first though.  I will keep my eyes(and ears) open for these speakers.  Thanks guys!
