Thanks for the picures of your installation. My "X hasn't arrived yet, so I used your pictures today at the audio store to discuss options in my install. I too will be gutting the entire Bose system and starting from scratch with Alpine gear including XM radio, nav system and Boston ProSeries speakers. Have you installed the Boston 10" ProSeries sub yet? Also, are you satisfied with the wattage levels of your 4 channel and sub amp? I'm thinking about going with only a 250w sub amp. Am also considering PrecisionPower amps, but there may not be enough space in the headrest storage area. They are bigger than the JL amps.
If you have some spare time I would appreciate having the measurements of the headrest storage area. It looks like you have a little room to spare. Also, is there any problem with excessive heat retention especially in the summer when there is cargo on top of them?
Thanks in advance.
