Hi guys
I am about to fit an amp and sub set up and although I have done this before in a standard car I am cautious about doing this in the WRX because of the keypad/alarms system.
Do I have to do anything different?
Do I have a timeslot to have the battery disconnected?
Anything to look out for?
Any special places to put the cables?

Sorry for all the questions but don't want to get this wrong!

cheers

Pete
