Yes, its very possible and very easy. I have a detailed post with pictures on how and where to run the power wire. Tap your remote wire into one of the non-important fuses located underneath your left knee. The LOC can be tapped into your rear sub. No wires need to be cut, there is a connector for this. Good luck. Get back to me if you need some more info. Look up posts by RR'12SiCp.So I'm thinking about getting a subwoofer for my 2012 si. I still have just the stock stereo w/o nav. Is it possible to hook up a sub with the stock radio? Is it possible to do it with the Honda nav system? Thanks guys
