Hoping someone can help me out I currently have a 2018 BMW 430i coupe I have a technic pnp running from amp using an audio control lc2i connected to an arc audio xd 1100.5 my issue is I’m trying to power the floor speakers to run HP but not getting any voice/HP filter is there something I’m doing wrong?

How does the ac part factor in? I thought the technic part went from head unit to amp directly?

No goes from oem factory amp to send clean signal then AC them amp

I think there are two versions of that pnp harness, one version only has the sub outputs. That might be your problem.

No I have the correct harness with both, the aftermarket subwoofer sounds great but I can get a HP signal for the floor speakers I’m thinking it’s the amp and or the AC

The lc2i only has one pair of inputs. You can only use both pairs of outputs of the lc2i if the input signal is full range.
If yours was connected to the OEM sub channels, you will not have any high frequency signal going into the loc, so how is is possibly going to have any in the output.

So what’s your suggestion? A dsp?

A dsp would give you the most flexibility and cost the most. You could also use a second loc connected to the proper channels of your oem amp to get the highpass signal you need.

So a lc6i could work? Thanks again for the help

Yep, an lc6i would work.
