Since the thread got bumped, I figured I'd post up my latest install. This last weekend, I confirmed that it's still too hot for any sane person to work in the garage all day.
The wife and I are taking our Tech license exams on Thursday, so to prepare, I installed our Yaesu FT-7800R dual band radio and Larsen 2/70 antenna.
Rule one for any gadgets I put in my truck is INCONSPICUOUS. I can't stand the big piles of radios, cords, and crap some people have cluttering the cab. No offense if you're one of those people, I just impose this on myself. That said, I spend a couple weeks (during my commute) thinking about all the places I could put this radio that would offer ease of operation yet be out of the way and unobtrusive. I finally decided a remote mount with the faceplate frenched into headliner with an external speaker mounted through the headliner overhead.
I picked the FT-7800 because of its 2M/70cm transmit capability, it's remote mountable faceplate, and (maybe most of all) its orange lighted buttons that match the Taco's dash lighting.
On to the install! I dropped the headliner down (not a short task). I measured to the center a few inches in front of the dome light and marked the spot for the speaker. I took the case of Cleartone speaker apart and marked the screw holes. I cut a small circle in the center to clear the magnet. I screwed through the headliner into the front of the speaker box. I used hot glue to tack the speaker wire down for strain relief and to keep it from bouncing.
The front of the headliner has a bubble right behind the rear view mirror that has enough depth to accommodate the faceplate. I (very carefully) cut an "H" shape and folded back the tabs to form a pocket. I screwed the faceplate mounting bracket into the headliner on the top and back. I hot glued the corners to keep the cuts from propagating. Hopefully that's effective.
I tacked the faceplate cable too, then reinstalled the headliner. I routed the speaker and faceplate cables down inside the drivers C-pillar cover. The last two pictures attached show the speaker and faceplate as installed.
