Nice work so far. I love how clean tesa tape makes things look. I keep it on hand for all my BMW installs.

BTW, are there subs (under the seat or something) in the e70? I ask because you say the factory subs are not enough. And, then if you have subs, why not tap the LOC onto those instead of the rear to avoid impacting your fader? Just questions as I am not familiar yet with the sound system in the wife's e70.
