So my other corrections to the front stage are I rewired both front tweeters and mids in the doors. I found that the drivers side mid was wired out of phase. I also found that the crossovers were set to -3dB for the tweeters, which would explain the lack of high end. Surprisingly enough both doors were dynamatted properly and the adaptors were made right.
The head unit is some fancy shamcy Alpine 8" touch screen that is not available in the US. I guess its made for the G8 and Holden Commodore (i think thats the aussie version).
With a high tech head unit and its built in DSP you get lots of adjustability. Great if you know what you are doing, horrible if you dont. Well the parametric EQ was set up all kinds of funky. He boosted the bad frequencies and lowered the frequencies that the customer likes (the customer listens to trance and dance music).
So I set the EQ properly.
Because of the issues with the front speakers the customer had to move the balance to the right because the system was left biased somehow. Now I am able to center it up.
Now on to the subwoofer. Its a 12" IDMax. Its a version 2 but has been reconed and according to Image Dynamics it uses the version 4 specs. According to the website it needs a 1 cuft, well the box that was built by this shop was just short of 2 cuft. Did I miss something? does the sub have 1 cuft of displacement? no it has .14 cuft of displacement. Also, the box was a basic 3/4" MDF box. Great, if they hadnt shaved off parts to make it under the amp rack.
So I made a new box. It turned out that I overshot the size so I made an adjustment.
and thats where Im at now. Without the sub I can say that I have the rest tuned in. Tonally and stage wise its as good as its going to get. I am very happy with how it sounds. I have used all of my test music and this system could compete with other systems with much higher end equipment. The addition of the sub will bring it to a whole new level.
