I disabled the DSP totally and went with aftermarket amps, speakers and subwoofer. It is still a work in progress but I couldn't resist to try out how it sounds while I am still working on the amp rack and the fiberglass subwoofer enclosure to fit in the factory subwoofer space, so I hooked up the system temporarily to listen to it and it sounds sooo awesome. . Love it.

If you are a stereo maniac, I would suggest to go with gears that you can upgrade later on. It's an expensive hobby but it's worth it .
