So I've searched around and am unable to determine the spot to tap the front speaker wires. I have a 2015 non-bose 3.

I'm not sure if it's the harness that connects to the infotainment system or if it's the harness connected to the amp under the glove box. I'm just trying to find a good spot to tap into.

So far, I think the wires are as follows:


LEFT Side: Light green +, Red -
RIGHT Side: Pink +, Green -

Any help would be greatly appreciated, thanks.

I only know, that the TAU (tuner and amplifier unit) is located behind the glove box and should be used. Details should add someone else.

I installed an amp in my 2018 3 non-bose by running the high level inputs from the TAU. It is easier than pulling the HU out I think. I ran the front and rear this way.
