to get rid of the engine noise you need to get some rem wire and ground all the rca to the body of the deck!!! i have the same deck in my LS400. yes it is possible to wire stock amp to any after market deck!!! problem is the sound going to be a little weak since the stock amp doesnt have any gain settings. some people rung the fosgate 360 and what not
