I'm taking delivery of my 128 soon (with the current stock sound system, the so called "Hi Fi") and such a scenario is what I want to do.

Between the head unit and the amp, I want to place a (ideally parametric) EQ, and using test tones and a spectrum analyzer, dial in the EQ close to flat. Ideally the same unit would also have some additional DSP that gives me the option to expand the stereo image a bit and maybe even deal with timing and phase errors (optimizing the sound for the driver's [MY!] head location).

Something like:

which seems to be going for under $300 online since it is out of discontinued and buggy, or RF 3sixty.1 or the JL clean sweep.
