    Worked in my 2012 Civic Si with the factory subwoofer. A little tip for those installing a LOC, if you have a factory subwoofer, tie the positive connections for the left and right speakers together and vice versa then tap into the positive and negatives of the factory subwoofer. Did that, have had no problems for more than 6 months
