I have recently disconnected my subs from a line converter to my HU that has 4 volt preouts. The sub is noticably cleaner & smoother. Not tremendously louder, but the SQ is greatly impoved!

And it is a lil louder too. :thumbup:

Right, you usually only need an LOC with the HK headunits because of their balance differential/high power (8-12V) output vs. an aftermarket unbalanced "normal" power (1-4V) preamp output.
