im thinking about getting a system in my car.
for those with current system sub installs in the 07+ sedans can you...

-post the grounding points in the trunk
-the mounting points of the amp or the box in the trunk
-and how hard was the wiring of the remote wire to the factory setup or was it done some other way
-and did you have to drill through the firewall to get the power wire transfered

any write up or actual pictures would be so helpful to let me get an idea if i want to go with this or not.
