IMO...stock speaker suck. You can get nice replacments fairly cheap @ Crutchfield.com.
They will fit...I installed 6.5" in front and rear (MTX = same set(s)), but you might need to make a couple of small modifications. Nice thing is Crutchfield supplies all the mounting hw and adapters needed for your install. If I recall, on the front, I had to take a tin snips and cut a couple of notches in the door brace. Nothing too complex....you just have to hold the speaker up in the opening w/bracket, mark and fabricate. To me, with the upgraded head-unit, my stereo's 1000x better now. Good luck!Wow thanks for all the info guys! Hey Iceman do you think those 6.5inch speakers will fit my front doors? Cause I know they won't fit in my back doors.
