I'm having a problem with the radio in my moms suburban I installed an after market radio and a sub but before I connected the amp and sub the aftermarket radio was working perfectly but wen I went to disconect the battery to install the positive gauge wire that goes to the amp after I did all that I than grounded my amp ran the remote and rca cables to the amp as well and now I go turn the car on and no sound I turn the car off and turn the key back so the radio can be on while the car is off and the subs and the radio work so am confused is there a trick for this year model???
