The door speakers in the new cars, and on some previous 1st gen cars, are supposed to be mid-bass speakers. They aren't built to carry the mids and highs. Those are carried by the dash speakers. As a stand alone speaker, you won't get the full range of frequencies you want for full music reproduction. They are designed as part of a larger system.
Conversely, a full range speaker will carry them all but not really do a good job of it. That's why you have "separates".
So I stopped by the shop today. My guy told me basically what you just said Maddog, the signal that is sent to the door speaker is more of a bass signal, whatever as the dash is a high mid and full tweeter signal with the rear dash being a full signal. So, the idea is to take the rear dash signal and copy it to the door and dash, powering the new Hertz mids in the doors with the new tweets also from a new 4 channel amp. This would allow the fader to works a fade for the lower door speaker and the dash speakers. The rear deck will stay as is but amped from new amp. Cost, around 600.00 to 650.00.
The question about the USB being on when the car is off, no it is not. Seemed it was only because it was always on when I was near. This is because of the keyless entry makes the car turn on. Take the keys Away and after a short time it shuts off.

So I thought I would post this just in case anyone else runs into this problem also.
The stereo shop I go to was talking to me about inserting some new door speakers, adding seperates. They would be a Mid and a Tweeter set up.The problem is that you need a full range signal and and as I and others have stated, the current Alpine system signals are split up or EQ-ed out of the deck, posing a slight problem. This means the only true full range of speaker signal is to the rear deck. The door is set up for Bass signal (which is where my sub signal for the new 12" is from) and then a high-mid and tweet signal is sent to the 3 1/2" in the dash. So, to get the mid and tweet the way they should be, you need to start with a full range signal from the deck to a new amp, then out to the speakers. So, we are looking at using the rear deck signal for the the signal. This is all good, EXCEPT the fader will not work (which is not completely true, it will, but only to fad from the door to the dash, but basically it will not work), AND the concern has been that there could be what they are calling a "Time Delay Signal" from the deck. Basically, the signal to the rear deck is delayed a very slight bit, which if you use it up front will sound really kinda funky.
That being said, I really appreciate the shop being concerned with this and not just installing it and saying well that is what you wanted. So they called around yesterday to several places, Alpine, Chrysler and such asking if the stereo was done with Time Delay, so far, there is a constant "No" but the shop has one more person to respond before they are convinced that it is not.
You may ask why all this, well as soon as I know it is not, a new Amp and Hertz seperates are going into the door.
Maddog, ever heard of this tie delay or know anything about it?
I know I have a time delay on my home theater digital signal processor which allows the speakers in the front and rear of the room to be in synch so that you don't get a nasty echo effect with the sound playback. I would not think a car audio system would have a time delay feature as the enclosure is so small compared to a room in a house.
One option to wipe out all of those concerns is an aftermarket amplifier.
Funny you mention the home stereo, Mine too has this. I have a 7.1 system that ironically cost alot more than my car stereo (well so far, LOL) and it does have this time delay, that I just re-set the other day.
The car stereo can have this. I know that in my BMW I had, I put in an aftermarket deck from Alpine that had it. It really is kinda cool, you can notice it a small bit, nothing like the home system though. By the, DO NOT EVER try to change out a deck in a BMW!!! Cost me well over 1000.00!! Damn things use a MOST Fiber optic cable that MUST run with the or through the stock system or it will always throw a code!! So, the stock deck was located in the trunk ONLY for the MOST cable!! Anyays..... LOL
I truely hope that I get the call that we are a go to install the new speakers and amp!!
Maddog, thanks for all your help!!
