1. is there a crossover some where in the wiring for the door speakers or are they crossed over at the driver . i will be installing a new component set soon and would like to use the factory wire.
2. on the factory battery terminal there is an open lug on there . is this fused? or is it there for other options i don't have. i would like to use that as my power connection.
3.are there any pics on how to take apart the rear interior peices.

sorry this is kind of simple i normaly just tear right into my cars but not this one i just want to have a really good game plan first.
