Question Where to get input for amp ? Adding 12" sub to HK in 16 M4

I want to add my jl 600/1 and a 12w6v3 in the trunk to add that low end that I like . Car is a 16 M4 with the Harman Kardon system. Is there a recommended spot to splice into for input signal? Planning to use an Lc2i will that work or is there any other complication or signal converter I might need to get a clean input signal?

thanks!

Someone makes a harness that plugs right into the trunk amp and provides outputs for you. I can't remember the company, but read through here a bit and you will find it. It made my install trivial. Not cheap really, but well worth it.
