i wouldnt get anything installed at bestbuy... look for a small electronics shop around your area they would most likely do a better job than bestbuy, that goes true for the 3 bestbuys around me have seen some horrible installs...amp power cables running right over the valve cover, spaghetti mess under the dash for alarms....its goes on...
