I went to a audio shop and asked about adding an amp and a sub to a BA system. They recommended the Audiocontrol LC2i instead of tapping the signal without boosting it. Has anyone installed one of these, or know of any diy threads. I have already seen the wiring diagram threads, just wondered if there was anything specific to this product. Also, if you have one,are you happy with it? Also considering the LC6i and just re-powering entire system, and replacing all the speakers if anyone has used it instead. How did you do yours? What made you happy? Thanks
