Cheap decent 6x9s for farm truck ?

Don't get planet Audio, whatever you do... I bought a set for the Dart while I was waiting on having money for a set of Diamonds and they had this horrible unbalanced sound to them that is just hard to describe. They were cheap, like $30 for a set of 6x9s. I've bought Pioneer and Kenwood 6x9's in the past and never had an issue, but these deemed immediate replacement. I swapped em out for a set of whatever was cheap at Best Buy which wound up being a set of Pioneer 6x9's for $40, and the awful, tinny, raspyness went away. Night and day difference.
