There is a harness from Metra (I believe) that will adapt from RCA of any aftermarket source to the OEM single preamp plug that will feed the OEM amp. However, this is NOT a long-term solution as whenever the aftermarket unit is turned on, there is a nasty loud pop and picks up noise also. This isn't because of the harness adapter, but because of the OEM amp'd system, as it uses a shielded harness bundle. In addition, the higher RCA output voltage may contribute to the noise popping that feeds the OEM amp, which accepts a much lower input. The best thing to do is to bypass the OEM amp and use the amp section in the Pioneer hideaway unit instead.
