6x9 speakers in front doors

^This relates to head related transfer function, group delay, and sound localization. You also have level and intesity differences to take into effect.

IIRC, above 15kHz to 20kHz a person's ears can very accurately discern the location of sound. This stands to reason why you see a lot of the OEM systems these days having a tweeter mounted in the a-pillars. It assists in raising the soundstage without too much, if any, equalization or time alignment.

There's a nice little graph that has been posted up, either by myself or Derick, that shows one the frequency breakdown illustrated on a graph. This is fundamental for learning your sound descriptors and ranges...as a matter of fact, here you go:



This is a really neat graph to work with.

Take note of what Derick and I are doing with our Yaris systems. See where we place our speakers and ask questions. Derick is learning big time as am I. I may have a few more contacts into the mobile audio world than the normal person and am happy (most of the time) to give advice. I'm trying to get Derick into IASCA competition on the NE. After my resounding siccess on the IASCA circuit out here in the NW, I absolutley know our cars can sound off with world championship potential.

Pay attention to what we do. Let us spend our money, it'll help you avoid some of our mistakes. One word of advice...BE PATIENT! Don't go out and blow your wad, have something go wrong, and then quit. Great sound is a learning process. You're not going to get the same sound as a million dollar sound room in your Yaris...you can get close though. That takes time, some money, and *ahem* patience.
