I'm NOT saying this to knock Etchus as they make a lot of great stuff for our cars, their double din kit is high quality and they do a lot for the SS community, but I recently had the opportunity to install both the Etchus kit and The DetailSS kit and I have to say, in my eyes, the DetailSS kit was a clear winner in quality. If you stay tuned, I'll be posting a review at some point on the SS Facebook pages comparing the two but I'll quickly explain the main differences.
first,The DetailSS kit has a much sturdier head unit bracket IMO that makes installing and adjusting the head unit a little easier. Also seems like it would slow a theft down a little bit.
the main difference that I liked better about the DetailSS kit though is that the way the Etchus face plate sits, it overlaps the factory faceplate in such a way that at the bottom it is really obvious if you look closely that the faceplate was an add on. The DetailSS faceplate is cut a little smaller and is designed to fit into a recessed flange left over when you cut out the old center piece, and because of this it sits partially recessed into the old faceplate with a perfect looking lip all around making it seem like it was molded like that from the factory. I'll post some pics of The DetailSS faceplate I just finished up below...
Again, you really can't go wrong with either kit, but I just think it's good to know about the differences because I didn't think there were any until I installed both.
