The objection of my system is (it never ends) to get a clear sound that is imaged correctly and sounds the way the artist intended it to sound. I am not into extremely loud music. 125dB is enough for me. Personally, the greatest challenge in car audio is to be able to reproduce ALL TYPES OF MUSIC at its best in this small environment. Before I actually get into anything, I should say that I won't be describing my system nor will I put any pictures of any car audio manufacturer. This section is exclusively a collection of DIY files which I hope will optimize the performance of any car audio enthusiast's system.
