Thanks all,

I just ordered my radio (Kenwood KMR-D562BT ), and I ordered both metra wiring kits(Metra 70-1784, and Metra 70-1786), the one with all wires, and the one with RCA so I can try different ways of wiring it to the factory amp.
Both kits, removal tools, antenna adapter, and radio came under $150, all via Amazon. Of course, everything will be here Tuesday EXCEPT the tool to take out my factory radio.
