I recommend tapping the sub + one of the front speaker. With the equalizer on the head unit all in the middle and the factory sub set to 4, this is the measured output of my amp with a 24 hz subsonic filter and a 24db/octave low pass filter active.
Tapping the sub only gives you a nasty peak 30hz that pretty much dies after 40hz. Tapping the front gives you a 70-80 hz peak that rolls off at about 12db/octave. Both of which are pretty terrible if you listen to a wide variety of music.
You could also fine tune it to a flatter output by lowering the sub output on the head unit, or raise my low pass filter to 120. I did not find that necessary because the factory front speakers have a pretty big peak output at 60-100hz and blends pretty well with the sub.
I use an audiocontrol ACM 1.300 which has a lci2 built in. I did not find the accubass really useful. I just set my gain with the head unit volume at 35. Make sure when you set you measure where your amp's peak output is at, and then use that frequency test tone to set it.
