Hmmm...So youve explored every possible option right. You know everything there is to know about the 'MP3car scene'? Am I taking this wrong or did you directly say that you know everything from experience you have had? let's see where I will start asking questions...have you put a DVD player in your car....Used a CRT...and an LCD character, graphic, full color? Have you TRIED a DC-DC converter...I mean ylu personally for every question I have asked. I dont want to hear about what you have read on other peoples sites. I want to here about how you have personally tried every possible option and came with the fact that your way is the best...isnt that how you put it?
The whole point of doing it yourself is to do it however you d*mn well please. then if you choose to tell people about what you did, I have a suggestion: Try the 'This is what I did' approach rather than the 'Here is my way to do it and naturally its the best so you better do it this way too' approach.
And as for creating this Topic for your opinions: If you don't want people to reply and to rebute what you might say..Put it on a webpage. Period. If you dont want people to contradict you ore expresse there opinions what ever made you think a 'Disscussion Board' was the place to do it...(note that word Discussion)
