Hi guys I need some help please. I have just bought an under seat subwoofer and was wondering if I can plug the power into the connections going to my double stereo (appradio). The yellow cable (power) that comes out of the converter to the back of the stereo for all speakers etc splits into two. One obviously goes into the stereo but can I use the other to power my sub? The cable coming from the sub has a fuse built in so I guess it should work? Cheers
