what kind of siren/light box?
that will help....
It's a SoundOff Signal 380R. Still trying to decide where I want to mount the remote head (considering the overhead console).
As for removal of the interior, not really all that difficult. I think I read about it on a Silverado board or something, but here's a quick overview:
Remove the bench seat. On the D/S floor there's a plastic cover with 3 plastic pins, remove to access the (2) 3/4" bolts. Remove the (2) 3/4" bolts from the P/S floor. In the center on the floor there's (1) 3/4" bolt that the two cables for the child seat securing system connect to. Remove that and pop off that bracket (I carefully used a pry bar to get it off of the bolt). Lift seat up first, then out.
From there, it's just a matter of removing everything else. It's all connected with pop in/out fasteners for the most part. As long as you apply steady pressure and not jerk on stuff, it'll come off without breaking. Remove the trim panel under the rear window first, then you can remove the sides. Use a T50? Torx to remove the seatbelts so you can get the trim panel off, then remove the seatbelt all together by removing the third T50 behind the panel. This allows great access to the grommet that goes into the rear door. I'd still be cognizant of sharp edges if you're going to run wires through here.
Everything else pops off pretty easy, including the rear door panels. Just two screws in the handle, and the whole door panel comes off real nice. If you ever wanted better speakers, that would be the time to put them in cause they are crap
I think my install on the lights in the rear doors took me about 15 minutes each, from mounting light, to panel off, solder/heat shrink connections, panel back on.
Headliner is pretty easy from what I've read. Just have to remove the trim all the way around holding it up, the upper console, and dome light and it'll come out real easy. I haven't done it yet, but that's next (I have an
SNM E66 and an
SNM E48 to mount).
