Audiocontrol Loc's
 

I'm almost done with acquiring all the components for my stereo build. The build will use the oem head unit for now. So I need a quality line output converter. Has anyone here used processors by Audiocontrol? This company claims to be able to take speaker level signals from any oem system(even bose-which is what I have) and convert the signal to a clean preamp signal that's ready for an after market amp.
