My car is a 2012 Acura TL base model, and I'm going to install a subwoofer in my car soon. I just need to know how I'm supposed to install the remote turn on wire while keeping the original radio in my car. From what i've read, people say to connect it to the factory amp, but it also seems as if the connection i'll be using to connect the sub to the stock radio could serve the same purpose. Any help would be much appreciated.
