When my 2000 323ci BMW arrived at Difeo BMW, I figured that I was going to stick with the stock stereo system.  It wasn't till about a month later when I decided that the stock system was unbearable. The sound quality was just not dynamic enough for me. I figured since I had all my aftermarket equipment from my previous truck and all I had to do was purchase new wiring and dash kit, it was going to be easy to implement an aftermarket stereo system in the BMW.  

     After about a week of thinking about the setup and other ideas,  I figured why not go and compete in sound off competitions.  So I made that my objective.  But I had to keep in mind during the whole process of the installation that I was leasing the vehicle. So just incase I decide to turn the car in, I had to make sure that everything was able to be put back into its original condition.

     I wanted the car to have a crisp, clean sound.  Loud wasn't a priority at the moment but I later realized it was a must.   I decided to put one 12" Sub in a custom ported box. The sub will be pushed by a 1200 watt amplifier at 4 ohms.  Instead of replacing the existing factory mounted  mid-drivers and tweeters, I left them in their location and amplified them with two 50x4 amps.  The brain of my whole system was the EPX2 by Rockford Fosgate. It enabled me to set crossover points for each speaker including the Sub and tweeters and allowed me adjust the frequencies on 28 different points.

    As I was nearing the end of the install, when I decided on purchasing a new amp and adding another subwoofer in a custom duel sealed enclosure. The reason for doing this was because the sound was getting trapped within the trunk, as a result the bass wasn't getting to the rest of the vehicle. So that is where I leave off.  My overall goal, To get the stereo system working!!!!  Isn't that what everyone really wants.
