[QUOTE="SkizeR, post: 8631015, member: 633600"] As mentioned before the main focus of this rebuild was total accuracy. Since i already have done work in this car and save all of my before and after measurements, i looked over the Before measurements from the last pillar mounted midranges, the frequency response of the previous midrange, and the frequency response of the new midrange. For the passenger side, it seemed like firing right on axis was the best bet to get the right frequency response and levels with the desired crossovers was firing on axis. The driver side on the other hand, seemed to have a slightly rising response in the upper frequencies in the pillar location. In order to combat this i aimed them at the passenger side D- pillar, a little less on axis than the passenger side. The difference isnt very noticeable, but its a nice step to take to make sure things are sounding the best they can. Another thing was that Mike wanted to compete, so i did what i can to keep him out of an unnecessarily high class. Here i am getting a general idea of how i want to put the pillars. [IMG]https://i.imgur.com/WXmpngS.jpg[/IMG] New pillars were acquired from the dealer for this, and immediately cut up. Driver side aiming. More cutting needed to be done to prevent blocking of the top of the speaker.
