Iam seeing a lot of different sizes in speakers for the STI and I just want to know the reg. size for the front and rear doors and the rear deck?? Also with putting a cd player in the car, do I just buy a 02 and up wrx harness for the cd player??
02-03 HU harness worked perfect. From my installation this weekend I would say diameter isn't so much the issue as depth. 6.5" should fit nicely in the front doors as for as the hole is concerned. However, you will need to be equally sensitive to the depth of your speaker as you are the diameter. There are lots of things to consider. I will be writing about my not so epic adventures shortly, and hope to cover some of these areas.
