I have a 2010 Jetta Wolfsburg with the factory touch screen deck in it. I want to hook my 12W6 in it without losing the factory deck. What do I need to do to get this to work without having to cut wires in my new car and have the best sound quality. I'm use to having an alpine deck with a eclipse amp powering 8 infinity kappa speakers with my mtx powering my JL sub in my old car. How can I get the best sound possible without altering a lot?
