Please understand that I am just reading the stuff on the box, I ended up buy a Kenwood Marine like the Op, its a Kenwood KMR-D768BT Marine CD Receiver with Built in Bluetooth KMRD768BT, I have removed the old unit and have the front going into the plug and I am running the REAR L/R wires from the tuner to the Amp hoping I can figure out which wires to clip for them. I will be replacing ALL the speakers because I believe I only have the RT door that even works. It will look good with the silver face and it can BT my guest phone. Thanks for all the help.
