Ok ive been reading a lot of info on sound quality in a car lately and i have to say that it isnt an easy thing to get, but im still gunna try and here is how im gunna do it. IM picking up the supplies for my kick panels today and im going to start really moving around all of the speakers in my car. Im going to place my tweeter midrange and midbass in a kick panel for the left channel on the small side wall under the dash to the left of the pedals and im gunna place the midbass for the right channel in a kick panel on the oppsite wall with 2 dummy grills so that it will appear to be even on each side. Then im going to place the midrange and the tweeter in a pillar pod on the right channel. Here is why:

In order for each channel to be in phase they have to be as equidistant as possible to the driver and this is the best placement i could come up with to achieve this goal.

In order to keep proper imaging the general rule of thumb for speaker placement when it comes to distant is that the speakers should be no more than half the wave lenght of the crossover freaquency away from the speaker that it is crossed over with. Which in this case the crossover freaquency will be 400 or a little less im still deciding on this.

In order to obtain the proper brightness in each channel im going to use a 3db boost on the tweeter on the right channel because im concerned about it sounding off of ballance because of its location.

what do u all think I know all of this sounds crazy and it doesnt seem like it would sound good but i think it will. The only Draw back i can think of is that the right channel may sound bright but i can work that out with some of the EQs and crossovers on my cd player

One of the biggest things i've found in car audio, is a flat response. And you can use multiple EQ'* bass boost whatever, but personally the highest SQ/Musical setup on my subwoofer, is like this.

Deck
Loudness ON
Bass +/- 0

Amp
Gain/Crossover accordingly set
Bass boost off.

The only real processor being used is loudness, and that'* affecting the whole system too.

Your Sound stage will be much taller on one side, because the drivers will be at different lengths apart.

Yeah my deck has an eq and other good features that will help me give it a flat response. I also chose the speakers because i get a flat response. As far as the sound stage sounding taller on one side I think i can minimalize this by angling and ballance controls. If its neccessary i can add a tweeter to the left channel on the pillar pod.
