Finally got the stereo installed ( or most of it) after much debating and research - thanks to all who shared.
I end up deciding to do a Nav unit - got a good deal on the new Kenwood Excelon 691 and matched it with a 5 Channel Excelon amp .
Speakers were tougher but after several test fits I decided on the Rockford Fosgate T165s components fro the fron and mounted the tweeter up mi of the A pillar (still need to find a good "pod" to get it angled better....) and then filled the rears with Punch 6.75 2-way rears......
I'm planning for the 10" sub mount so the 5th channel with drive that..... still debating using the headunti to power some 4 inchers in the dash as filler - but worried about them messing with the sound stage
along the way I fat-matted the whole dang trcuk - 3 layers on the doors and 2 layer over all the flat surfaces along with a 1/4 foam dampener matt across it..... can't wait to get the rest of the interior back in to hear how it sounds but have some wiring of stuff for the center console
