One of the chief concerns I had (and based on some forum responses to the similar install, a concern for others) was the now-open vent ducts blasting the back of the radio. There were a couple of mentions of perhaps using the small open space along the top left of where the radio would be and 'routing' the air flow to that spot, thereby keeping at least PART of the center vents. While an admirable idea in theory, it would become a LOT more complicated in terms of fabrication. Because then, you would have to fabricate a ducting 'system that would have to create a good seal behind the radio and snake it's way around and to the side of the radio to exit at the aforementioned open space. Then there would be taking the current vent, reducing it in size, then further fabricating a mounting structure to keep it in place. A lot more work than even I was willing to undertake for this project.So, I instead decided to just completely eliminate the center vents entirely. Now, before you say something like "I like my center vents" and "I can't be without my center vents", let me elaborate on this idea a bit. During my initial part removal phase, one thing I noted of course, was the amount of air which came from the front and two side (passenger and driver) vents, as well as the lower foot and upper window vents. With the center vents 'plugged up' (this, with a rag at this point), and with the HVAC controls set for the upper (not window) position, the volume of air coming from the side vents increased dramatically. And this was with the fan set at "3". And since the same side vents able to be directed pretty much across both passenger and driver seat, It could almost be said that the center vents were redundant. And since nobody at this point documented just HOW they did this, I decided to do it here. Let's get started, shall we?
