tweeters

Whoa look at all these posts and no one is telling wrathchild *why* what he's trying to do is going to sound so bad.

wrathchild, when you start adding speakers in the manner you are talking about, you wind up not adding sound, but in many cases canceling what you have out and muddying up what is left.  I couldn't imagine how your setup would sound but it is sounding so incredibly bizarre that I'm having a little trouble just imagining how you came up with this setup.

Think of dropping two stones in the water.  Ya know how the waves will hit each other and disappate each other? That is kinda what happens when you start adding speakers around a car in the manner you are talking about.  That is why we are telling you it is such a bad idea.  Lotsa buzz-words and heady sound-philosophy here.. but the fundemental idea here is that more really isn't better.

Ya know how if you drop two stones in the water, but you hold them close together, and they make one big splash?  That is why Poormanq45 is telling you, if you are dead set on doing something this goofy, do it with an extra componet set, not 4x4"... if you mount one in a kickpod and the other in the front door, *close* together, you get much less of that cancelation effect... and you'll be closer to your goal of more sound that you'll ever get with your 4x4 plan. 

Not only that, wiring a midbass in parallel with a tweeter b/c thats the only way it'll work, especially given all the other equipment you have, is completely retarded.  I can't even address the ridiculousness of such a proposition without my head almost hurting.

You say "come on guys, ppl with 8 12 don't just have 4 really nice speakers" .. I don't really know how else to tell you this, but usually ppl don't have 8 12's at all.  I really don't know if you'd even be able to design a high end that would be able to keep up with that sort of pressure.  What kinda of vehicle is this behemoth system in?

Poormanq45 is right, if you want to do this the way you want, you need new mains.  A 3-way setup with lotsa cone area.. bridge the entirty of that 50x4 to them and run your 6x9's in the rear.. 6x9's have lotsa cone area anyway, that is ur best choice there.  Add an extra set of tweeters in your A-pillars..  but that'd be about it.

It'd be loud anyway.

Huh. I got so wrapped up in why that is such a bad plan I never actually answered the question.

I don't really want to.

You'd want to run your tweeters off of one pair of channels, and  the 4" speakers, wired together in parallel, with the other.  That way the same size speakers would be getting the same signal.  That is kinda important.

Of course, getting a signal that would do that properly is kinda another story.  Ya need a signal processor for something like that..
