Im thinking about adding a aftermarket sub and amp to my stock system. Does anyone know what wire and where to tap for the turn on signal for the aftermarket amp? I have a 2009 TSX. I'm looking for an accessory wire, I just dont know which one?

 

There are some new LOCs out, Stinger being one of the manufacturers, that have the remote wire built into the LOC so when you turn on your car and the radio comes on, the LOC detects the current and will turn on your amp. No more tapping into fuse boxes.
