i know this may not be relevant to this forum but i was wondering if anybody could help me wire my sub/amp to my civic lsi. from what i know the
- red power wire from the amp connects to battery terminal
- brown is earth
- two sethrough type wires are spakers/sub etc

- but there is a thin blue wire which connects to the amp and runs down to where the head unit goes. im not sure whre this blue wire connects to any help please.

thanks

 

the blue wire is the amp lead wire and it connects to the corresponding color from the headunit (assuming its aftermarket)

 

it bascially tells the amp to turn on or off when the HU is on/off
