dude it freakin rocks! It goes inline with your existing bose system. It does not hinder your stock system at all, but what it does give you is: the ability to hook up an aftermarket amplifier. The big difference between it and other "converters" is that it does it before the bose amplifier! That way you get a clean, unprocessed signal. I hooked it up to my Kenwood 500Watt amp and 2 JL 12" subs. It is perfect for adding deep bass to the stock system.
