My m3 is coming withen the month so I am starting to look for possible speakers to replace the 95 stock system. I like the mb quarts and was wondering if anyone had any feedback about how they installed their 6.5 in. q-series speakers. How hard is it to custom install the 6.5's and also to put the tweeter and mid-range in the kick panels together? Also I was looking at jl audio stealth boxes and was wondering if anyone had any complaints about rear fill with only the 8's in the back. Also how many watts are you guys running to your stealthboxes and quarts? Also where did everyone place their amps? I will probably run two seperate rockford fosgate amps. 90x2 for the fronts and 125x2 for the backs. Any other feedback would be appreciated. thanks
