I got my hands on a a set of individual amp and speakers and surprised there is no retrofit guide for hifi to L7 or EPS that I can find.

Most people that attempt to retrofit the Logic 7 system just get the entire
setup out of another car , including the harness.
There are retrofit guides for this on the Internet.

the 752 amp has a separate power cable I believe and how it's wired
in I don't know.

Also there is a wiring diagrams for the members thread at the sticky section of
this forum.

This will end up being a can of worms for most people and for not that good of
a system.

For people going to the Individual amp from Logic 7 you never here about them changing
the wiring . Some say the 1A amp is drop in . They sell them on ECStuning and say pretty
much the same. Power Cable is the only thing different I think as far as hardware is concerned.

Does anyone know if the HK system from a 2007 E91 will fit in a 2011 LCI model?
