Remote Lead for Power Source in 2015 Allroad...Anyone?

[zcspec]

Today I tackled the project of adding a powered subwoofer to my 2015 AR's B&O system. During the wiring test-fit, my attempts to finding a remote 12v accessory source was unsuccessful. I used the following DIY: http://www.audizine.com/forum/showth...ier-Add-On-DIY. Unfortunately, the AR does not have an entire red row of switched +12V fuses.

I even went down to Best Buy and the master installer tested all my fuses and they're all live. His manual recommended grabbing the power source from the cigarette lighter up front. I'm not about to tear apart my car just to get power from the cigarette lighter.

As anyone successfully found a 12v accessory source from the back panels?

I think most people are using smart amps which turn on and off when they receive an audio signal.

I may have to go that route.

I think its all the B8.5 A4s/Allroads don't have ACC power fuses in the trunk, only place is in the front fuses behind the dash.

You can tap into the parking brake module as instructed in the below trailer electronics retrofit PDF on slide 2(pg 11, they're saying the ACC lead should be black colored, but test with multimeter) and slide 38 (page 29 - they're showing how you use an inline splicer to connect to this lead.)
