Thanks fot the input guys!!
With regards to the trimming, I am starting to doubt myself now!!! Any suggestions on colours/finishes etc i think would be gratefully received! As you might tell from my reply to Lexx, I did debate it a while and came up with the black being the most suitable choice but I am prepared to listen to other ideas!! I do have a good friend who is an excellant trimmer so I could get him to do a very good job but I wanted to at least try the trimming myself first! tbh, I want as much of this car to be done by me as possible and at the moment it's only the paint job that hasn't been!
As far as speakers go, I am obviously running the two Focal 11" woofers in the boot and am running 3 way Utopias up front. 6", 4" and tweeter in each door. I would love to try the tweeters in each location but due to time constraints in the next few months, I need to get these doors built as soon as possible so really need to choose a location before I can actually listen to the system! Not ideal I agree but something I have to live with!
