Pretty self explanitory. Bout 2 months ago my digital gear lights (P,N,R,D..etc) would go completely out and then turn back on. This past weekend a buddy and myself installed a set up subs, well after we through everything back 2gether those lights went out yet again and haven't come back on, or even flashed on, since. Its been 4 days with no lights. Obviously I know where all the gears are but what needs replaced or how can I diagnose this? Thanks!
