I know its seems at times like youre explaining something to a 3 year old but
I have a couple of questions that i wanted you to shed some light on once and for all

1. I wanted to know in your system that you did on the x5 and which you used the (front: midbass midrange and tweets) output for the front and rear door speakers were you able to cross-over the rear door speakers or did you play them full range?

2.the reason why I am asking is that is it possible to seperate between the midbass and the tweeter via the crossover if you are only sharing the remaining 2 channelss from the front ?

3. If a person goes with (front: midbass, midrange and tweet, and sub) like you did and ommited the rear channels then combined them would you basically be talking about 5 loc's on 10 channels is that right.?

4. On a side note i have been shopping around for a shop that understands some of the stuff that you laid out about the breakdown of the factory set-up in the x5 ,But the question that keeps coming up from some of installers is, why am i trying to seperate between front, midbass midrange and highs when they are all on 1 amp and not a seperate amp?
and that i would not be able to fade between front mid and tweets no way from the factory radio since the factory head unit only allows front and rear fading! Most sho buy into the notion of just Front rear and sub and have not figure out that its (6 channels up front 4 rear and 4 subs)

I think i carried this thread longer than it needed to be carried, but i appreciate you taking time out of your schedule to answer some of the questions from the members on this forumn..including myself.

Thanks a million
