OK well I wouldnt want to spend over 200 dollars so that leaves it wid open pretty much and I was looking at parts express for the parts I am planing on doing a custom install that would use the door panel so that it would require less work to replace anything. And yes I do have a sub its a 12" rockford HE in a sealed enclosure and I would prolly be building hte cross over if i cant find a good pre-made one. I was looking at bullet tweets they looked like they had a really good frequency range and all. Plus they would look good. See plan for my interior is blue vynal and i would be doing the doors in this and would be removing the factory speaker grill and replacing it with a peice of plexi glass that the speakers will be mounted into. I hope this would work, I figure I will prolly need to do some bracing and all but oh well.
