u know that section of plastic...directly above the center console, to the left of the z28 emblem..yet directly under teh dash mat!?! what behind there..been thing about drilling for a while now...
either a min 6'' or so screen and two 4 titanium bullet tweeters...or 3 4'' speakers?
any info gang

 

anyone ever did it? or anything like it...would love to see pics

 

do a search for Jim85IROC, he did something almost exactly what you're thinking of. may have some good pointers

 

did some searching couldnt find any pix/posts about it! he is a VERY active poster..lol
took my dash mat off today and looked around...looks like a relatively clear shot

 

did some digging, but unfortunately all his photos are dead links now (forgot he did this back in 03, wow time flies). shoot him a pm, he may still have something kicking around.

 

behind that area is a wiring harness and at some point in the center there is a metal brace to help support the dash assembly. The center ducts might run down right there too. I wouldn't drill directly into it without dropping the steering column and partially disassembling/ separating the dash shell. Otherwise there's a very good chance you'll drill into something you don't want to.
