i got infinity 4x6's in. i got a fosgate h.u. both sound great (getting a pioneer soon, price is right, same stats, just has mp3+aux on it)
i'm getting some good subs from a friend, so now my next focus is what are a good set of 6x9's that will sound good, aren't real expensive and fit into the factory space?

I have those inifiniti 4 X 6's too! They are good!

I have JVC 6 X 9's. They have monster magnets and deliver good bass

Stick with Infinity for 6x9's. I have Kappa 6x9's and they are AMAZING. The magnent on them is huge, they are so big I had to cut my rear deck in order for them to fit, but it was well worth the hour of effort.

does anyone know anything about soundstream speakers? i found a good deal on trantula 6x9. $100 for a pair... sounds pretty good.
