Grrrrrr, having done a few audio installs before, I didnt think there would be much of a problem doing an amp & MS8 install on my E90 but I am man enough to admit that I was wrong!

I've got two new under seat woofers installed, the wiring harnesses fed down the side of the car and into the boot, removed the head unit but there is not a chance I can do the following:

1. Piggy back the harness into the back of the head unit and get the head unit to go back flush
2. Get the wiring from the new centre to somewhere resembling the head unit / lower glove box area.

Anyone in the North West do this for a living and want to do these two things for me? Paid, obviously!

GRRRRRR!!!

Took me an age to get it right mate. I had to remove glovebox to get in there with a hand to lever it in well. PITA but be patient with it mate!

Don't give us.
1- Start with central speaker and use the torch from the top (central speaker hole). Your head is to be next to windscreen and looking from the top to direct it. You need to direct it toward the central dash air vent and further down toward the glove box. You'll get this down near the glove box and from there you can direct it to the rear of the car.
2- I assume that you have idrive and hence having issues with the harness.
You should be sitting in the NSF. Once the wires are connected to HU, you should be pulling the network of wires from the spot below the glove box while pushing the HU, so you have minimum network of wires behind the HU. Once the HU sit flush, leave the slack in the wires below the glove box so in case if you need to remove it at later stage, you could follow the same procedure.

I'd suggest you to take frequent breaks and kitkat

I bet your hands are already bleeding.
Fun part begins when you strat tuning MS-8.
