I have a sundown audio amp and subwoofer that is hooked to the stock bose system on my 2012 infiniti qx56. Initially it was hooked up with a loc that was tapped to the rear stock subwoofer but anything below 35hz wasn't hitting that hard. The lower hz the less loud and sub movement. I parked next to a friend's car to plug his rca to my amp and could pretty much go as low as we tested. I purchased an audiocontrol lc2i and replaced the loc but there wasn't much difference if any besides the gain and boost on it. Will I have to get the signal elsewhere? Before the bose amp but aren't they low voltage signal? I couldn't find any wire diagram for the vehicle. I'm ok with the sound on the bose amp and speakers. Do I need to get rid of the bose amp and get a sound processor and rewire all the speakers? Need an efficient way to do this
