I have an 09AWD with the base system.....Crutchfield tells me that they do not make a harness for my car after I sent them pictures of the connectors, this is not that big of a problem since I am using aftermarket HU, speaker amp, and sub amp for this install. It would be nice to know if there is a factory amp hidden somewhere so that I could tap into it instead of running new wires to the speakers them selves. Does anyone know if there is an amp and where it is located? Thanks
