The thread has almost all the information I need to install a mono amp with a sub to my HK system.

Yet I have one question about this statement below

"The HK (or Bang & Olufsen) systems subwoofer outputs have pretty high voltages, upwards of 25-30v"

The amp I'm planning to use has maximum of 10V support for high level inputs. So I definetely need the recommended LOC. However, another option is to use one of other speakers output (say rear left) which I assume is lower than 10V. Is my assumption correct? Subwoofer outs may have low passed signal. Rear does not. So I'll count on my amplifiers LPF here. I'm not changing the balance/fader anyway. This way I can eliminate the need for a LOC, hopefully.

BTW I don't have ASD on my 2.18i. So I assume, car doesn't have the ASD module. Not sure if it will ease some things for me though.

Thanks a lot for the precious information. There is no other word about this topic on the whole internet. Very much appriciated.
