There is one more trick option for you... The DSP amp is dependent on the factory radio are co-dependent. If you remove the radio, the DSP amp gets lost. So, if you connect your radio's "I-Bus" wire anywhere else in the car, then the DSP amp will be fooled into thinking that it is talking to a normal factory audio system.

In a nut, if you connect the radio to switched power, constant power, ground, and I-Bus anywhere else in the car, this trick will work. The volume control on the steering wheel and MID (if you have your MID) will still work. You just need to feed your current radio's front channel audio outputs to the DSP amp in place of the factory radio. Then, you set the volume level on the aftermarket radio to a maximum level to your taste, and leave it. After that, you adjust volume from the steering wheel or MID.
