Exactly what they said. Its not hard to do. I used to install at the Best Buy in Southgate on Dix and eureka. There is one sweet Car audio place in Taylor i think it was on Ranchero drive kinda over by the Star moive place. That was 5 years ago though they might have went under. or Palco electronics on Eureka in southgate kinda by the outback if going towards taylor its on the right side with a big whale on the sign. They are always helpful or atleast where long ago when friends of mine where on the Orion Kick. any more ?'s just ask.
