I am new here and appreciate all I have read so far. I have not discovered a real answer for my question though.
I am starting to make a list for my stereo install. I am considering door speakers thus far. My goal with doors or mid bass speakers is to have enough rich sound as to not need a sub at all, even though I will be adding one. I have done some door Speaker experiments in my last '04 expy (I currently have an 03 Expedition) and I lost considerable bottom end from the OE speakers. At first I did nothing but bolt in some pioneer replacement 5x7 speakers. No mods to the doors at all and the factory sheet of plastic behind the door panel was intact. I then tried an adaptor plate and some component speakers. Still sounded very shallow. I then tried building little enclosures behind the Speaker and it still sounded like crap. I even added some stuffing thinking maybe it would help. No good.
So, with this truck I thought I would take in to consideration what Ford installed, my front speakers are what look like a 4" woofer and tweeter in a little plastic sealed case and my rear door speakers are just the standard 5x7 looking speaker in an open type enclosure. So, the front are in a sealed enclosure and rears are not, what would sound best with aftermarket speakers? Should I attempt again to Build little enclosures around the mid woofer or leave them open? Why the difference in the front door and rear door oem speakers? Any advice?
After much reading I am being led to believe that sealing up the inside of the door, sound deadening the door, and sealing behind the door panel may offer the best sound but should I go with what Ford did in the front door, which is a tiny little enclosure, or go with the back door design using the entire door as an enclosure?
With a truck this big should I try using some sort of 8" mid driver to get the sound I want? I mean, as far as scale is concerned, does big space need big speakers? Maybe an 8 and a 6.5 and a tweeter in each door? There is plenty of space after all.
