Where to tap signal? Base stereo
Hi, I have searched, but can NOT find anyone telling how/where they did this..
2009 e90 LCI BASE STEREO.
I have a trunk sub, and have tapped rear speaker-signal..
Was going to tap underseat-signal today, and took out
passenger seat..There I found 4 wires, in the connector for the sub/midbass.
As I need left AND right underseat-signal for my converter,
do I have to take out driver side seat for tapping left signal,
or are the 4 wires on the right side, for both left and right "sub" ??
Really confused now..
I believed both left and right speaker cabels went on one side?
If so, dont anyone know the colors for left, and right side? witch is ground and witch is positive?
