OK, I got my Vaistech SLI line-in box. How much of my trunk do I need to take apart to get to the head unit in my LS430? It looks like the right side trunk liner has to come out, but is there any more hidden stuff that has to come out?

Also, where have you guys hidden the Vaistech box? There doesn't appear to be any room by the head unit & DVD system.

One more thing, any suggestions on how to run a set of RCAs up to the front seat? I don't see a good path out of the trunk.

I'm not a total car stereo noob but this is a bit more complicated than replacing a DIN radio in my old Integra!!
