Hello Folks,
I am working on moving my 15-inch Kicker L7 over to my new e60.
I got a box that is the perfect width of the trunk with 3.85 cu/ft.


I have found a number of posts on this, but they are a little muddy.
Here is what I have come up with from reading others, but I want to make sure.

Here, we have the trunk factory sub amp harness:


From others' messages, it sounds as though the four black&stripe wires on the left are low level lines from the stereo.
0.75 SW/VI (Black and Violet) pin 13 AZBL- [Line level Left input -ve]
0.75 SW/RT (Black and Red) pin 3 AZBL+ [Line level Left input +ve]
0.75 SW/BR (Black and Brown) pin 4 AZBR- [Line level Right input -ve]
0.75 SW/WS (Black and White) pin 14 AZBR+ [Line level Right input +ve]

So I don't need a Line Output Converter, I can just splice in my RCA Wire Leads here, and run them to the aftermarket amp?


So, I am looking for some confirmation that this would be a decent route.
I was lead to this conclusion from Bruce on Post #2 here:

Thanks all!

contact Technic and buy his harness, that will make this project a plug and play thing. taking all the guess work out and also for you'll not have to cut or splice into your factory wiring.

I guess the idea I liked about this was that we can hook right in to a low level, instead of amplifying this low level and then reducing it and then amplifying it again.

Otherwise, I would recommend this box to anyone with a 15-inch square sub and an e60.
It's a perfect fit:
