Amping front speakers and adding a sub.
 

Following on from the low level output tread, I will be doing this modification very soon.
I am planning on adding an amp to the front speakers and also a sub.

I have a non amped system and have a few questions.
1)
To connect to the front speaker line out i use
pins 1 Front Left +
8 Front Left -
2 Front Right +
11 Front Right -
5 Remote turn on
Would i be correct with the above?

2)
Do the speaker cables run directly from the module in the boot to the doors?

3)
Is there a cross over anywhere in the system.?
