In reality, there's no such thing. If you're good with a dremel, make some 6x8 to 6.5" adapters out of MDF, or have someone make them for you, and put REAL speakers in there. 6x8s are pretty much ford specific crap.
In a word.... No. if you're looking for something cheap, then I'd go with the alpines, but if you're looking for something GOOD? I'd rather make the MDF baffles for $10 and mount a real set of components.
6x8 and 5x7 are the same thing, people always argue that they need 6x8 for there ford, and i tell them 5x7 are the same dame thing. So either way a 6.5" will sound better then either, but yes alpine does make a good 5x7
as for good speakers... I found that for the money the pioneer rev series sound great
6.5" components for the front and 6x8 for the rears. These are pioneers best...so i was told. Supposedly they are Pioneers competition serties speakers. Ilistened to them at the stereo shop and they sounded awesome. Can find them online for about $150 for the fronts abd $100 for the rears. I'll be putting them in soon and tell ya'll how they sound.
