Best route for Technic harness

black 335xi · 09-17-2011, 02:39 PM

So, I'm well into installing some underseat subs and aftermarket amp in my e90 sedan, and I'm wondering if anyone has some words of wisdom regarding the best route to the trunk for technic's harness.

I've searched the forums and DIY's at length, and other than some generic advice re: going under the door trim panels or carpeting, I've yet to see a concensus regarding the best (i.e. easiest and least conspicuous) route from the hu back to the trunk. Any advice would be greatly appreciated.

In my opinion straight under the dash on the near side of the car and it all fitted straight under the plastic trim along the length of the car to the trunk. No issues. Plenty of room.

We are dealing with both left and right hand drive cars ?
I was told by someone the battery side of the car had more electrical
noise because of the power harnesses and other stuff on that
side. Wouldn't you want to avoid that side.

What does Technic recommend?
