A couple of months ago, I purchased the Kenwood / Sound Gate combination to add Sirius to the factory HK head unit. I won't cover all of that information again, as if you're interested do a search and it will be there.

I finally had the opportunity to button down the installation, as the units were just sitting there, but working fine.

I decided to hide the cextra cable and Sound Gate unit behind the door that the Kenwood is screwed down to. The HP amp is also in there, so there's little extra room.

The antenna wire goes through the gromet at the top of the hatch by the roof, where so many others have run it.

Here's a couple of pics of the finished look.

ps. With the antenna here, the signal is blocked with the hatch up.
