Adding amp to 95 BMW m3

I have diagrams of the pin outs here http://home.att.net/~ebaines/e36_leads.htm so i know what wires are what. The amp is located in the trunk so any speaker wire is easy to tap into.

I thought the best thing to do is splice into the Radio Connector in this order:

But on the page it says some of the wires color codes may be messed up so i figured you could just leave those out and go by pin number like this

Pin #1 = Left Front Positive

From what i've geatherd from you i should splice into the "Radio Connector" (singnal wires before amp), solder in the RCA cable, and plug them into the RCA inputs on the amp correct? If i do that everything should work good? In your mind does this seem to be the best thing to do in my position?

Yep that's pretty much all you have to do and that's probably how I would do it if I were you.  And yes I always try to follow the pinouts and disregard the factory wire colors because as long as the connectors are the same size/shape, the pinouts remain constant from year to year and between models.

Usually when I'm tapping in to  or splicing into a wire I'll leave the wire intact.  I strip off about an inch of insulation from the wire, twist the other wire around it, and then solder the connection.  Tape up the joint with some good 3m tape, and usually I'll put a zip tie or two around all of the connections when I tape up the last one...just keeps everything nice and neat and relieves stress on individual wires. 

Well the way I do it, I use wire strippers and squeeze in one spot to cut the insulation, then i move about an inch over and squeeze again to cut it again.  Then usually you can just push the insulation to one end (while squeezing) and it'll just scrunch up and leave the bare wire intact without cutting the wire.  It's kind of hard to explain but this is the way that I and most other installers I know do it.

Well it looks like my install will be delayed. I went to my cousins party and someone hit my car and left. Now it looks like my car will be in the shop for the next month.

Can anyone help me find a good BMW shop within 50-100 miles of Mobile Alabama?
