Nope...no need to cut any wires. You just needs some of these "wire tap-in squeeze connectors" => http://www.radioshack.com/product/in...entPage=search. One connector for each wire you want to tap...very simple procedure. You'll probably end up needing 5 since there are about 5 wires that you want to tap into your OEM amp (4 for speaker inputs: L/R +/- and 1 for remote turn-on).
