Tweeter Placement
I just want to interject here. From an SQ standpoint it is not always necessary to mount the tweet within 6" of the mid range driver. The main reason people do this is purely for time alignment and to prevent huge differences in pathlengths. If you have time alignment and attenuation control then you can put them in the A-pillars and that will result in a higher and wider stage as well as additional depth in many cases.
In short there are tons of places to mount them it is just that complications can arise from seperating them and making large differences in pathlength without some form of compensation. Be it either a Linkwitz Transform or DSP.

OK I will break it down further.
SQ=Sound Quality. Sound quality is as perceived by the listener to be good sounding. More accurately SQ would be to closely replicate a live performance in all aspects such as room size of original recording (called ambience), accurate tonality of voices and instruments being played back, accurate recreation of the stage and placement of the instruments. Accurate staging would essentially mean that if the singer is standing in the middle of the stage and his/her voice is recorded equally in both speakers then you should b hearing the sound from smack dead center of your dashboard. If your stage height is correct then the sound should also appear to come from horizon level or slightly higher. In other words you should not be able to close your eyes and point out where the speakers are.
DSP Digital signal processor. Most DSP's allow you to use time alignment or delay in milli-seconds on the speakers closest to you so that the sound wave reaches your ears at the same time as all other speakers. In short we know the speed of sound is constant so we know how far sound can travel in 1 millisecond. If you have one speaker closer to you then my delaying the signal going to that speaker it will make that speaker seem farther away to your ears. In other words the pathlength (distance between your ear and speaker) can be changed by delaying the signal a few milli-seconds.
Linkwitz Transform is basically a very simple op amp that will allow you to do multiple things similar to a DSP but more complicated for the new user.
Hope that helps!

Ok so we have some good ideas of where we "Can" and want to place the tweeters, BUT where are you guys mounting your crossovers?
I have a set of BC Pro Series with realy nice looking crossovers, but i am having a hard time finding a place to mount them and keep them safe, an ideas, pictures? ect..

Mine are mounted just above that 6" woofer you see above, but i'm not in the norm. I think if they are small enough that there is enough room (2004) under you window controls inside the door panel but outside the actual door. Do not put them where there gonna get wet. You might try looking up above where your feet go, i'm sure theres plenty of space up there.
good info..
so in the armrest, or above the woofer... interesting.
I was thinking about it and I kinda want to have my crossovers visable Why? you ask because i think they look realy nice see:

anyone have any ideas? Thanks!!

I was going to do A pillars for my tweets to, problem is with these Ford cabs is you end up with huge pathlength differences between right and left. From a SQ standpoint kickpanels would be the best location. Aside from that, and I havent done it so I dont know how bad it would be, but I fear with all the glass and plastic on the dash you may end up with some pretty bad acoustics in addition to the pathlength differences. If I do A pillers it'll probably be a seperate set of tweets at around 12,000 hertz and up to help raise the soundstage. Dunno yet though.
But it surely looks cool!

I tell you Shockwave, with the time correction and using them as additional tweets, I don't notice any negative affects on the imaging. It's all good
I'm not sure what the x-over point is on mine. I'm running them through the sat net x-overs with upfront technology.
I would tuck the x-overs away pretty or not. Just get them in a safe secure spot.
