Does anybody have 4x6 speakers that they are happy with? I am looking for something to replace the Polk EX462s that I currently have in the front of my Jeep. The Polks have decent sound quality, but are not nearly loud enough (jeeps are f**ing loud). The speaker mounting location sucks (about half way down the dash facing slightly downward with about 20% of the speaker obscured by dash plastics) which does not help. The amp I am currently using is a MTX Thunder 204 (25w x 4).
