Can you tell me more about the ULS up6 line of speakers to be honest I have never heard of them..

I had Diamonds hex in my previous car which was a lexus Gs430 it sounded pretty good, but you are right about the low end and the loudness not enough mid bass also, but otherwise a great sounding speaker
.
my other option for staging were cdt -audio cl-62-560 or cl-61-560 or Focal 165 k2, mb quart q series

As for the phoenix gold Amps i knew these were the amps that i wanted to use so i purchased the 800.1 4 months ago from a local shop that was clearing them out and the 500.4 last week from ebay.

As for the reason I waw going with the LC6 I am not trying to reproduce 14 channels like the OEM amp. I just wanted front rear and sub, and i figure instead of doing what Janix did i trying to reproduce all these channels and you cant control them from the head unit which only allows you front and rear so i just decided to go front/ rear/ sub.

I used the EQS as an option for further equalization from the lc6 but I guess i can always just use the cross overs from the components or go with an EQX.
either way I think that its an upgrade from the factory system. but I totally wanna be in control of designing this system. because while you have a lot of installers that make your trunk look pretty, they are often clueless when it comes to the dealing with wiring a bmw and their dsp system.
