thanks a ton for all your advice, guys.
i have seen you guys persuading a 10k budget guy to finalize a 20k ICE. thats why i mentioned a 10k budget first.
i think JBL GTO607c (6.5" 2-way comps) will fit in the front stock location (it is 6") and GTO607c is packaged with 2 metal adapters which can be installed in 6", 6-1/2", and 6-3/4" openings according to the manual.
about the headunit, there is still confusion. pioneer 7950 is a HU where you can plug in the USB rite. it is around 10k in grey. is it worth it?
speedzak and hydra@ am planning to do the installation by a friend who works at automate.
