Jimmy, wasn't directed at you. My professional opinion was for someone who hasn't bought an amp, and who also may not want to give up room for a subwoofer.

The reality is if someone wants to keep their factory controls for audio, they need the dsp to make up for the what you solved with a alternate head unit. Agreed? You can make it sound great without, as proven above, not absolute.

I measured 130+ db at my speakers without noticeable distortion. I would put a major prize bet that can't be done without active setup.
