Here is a picture of my Alpine CDA-7949. This headunit along with the Alpine PXA-H600 processor is the best SQ setup that I've had thus far.
This is the Alpine PXA-H600 Digital Phase Processor.
I had both of these units installed in my car a couple of different times. I really like the sound that this combo puts out. I had the 7949, & changer hooked up to the processor with fiberoptic cables, and the processor was taking care of the digital to analog conversion.
This is the microphone that the processor uses to do the automatic setup.
This is the control unit that allows me to setup the processor by hand. I can control paramaters such as time alignment, subwoofer crossover frequency and level, and it also allows me to adjust the 4 band parametric equalizer(4 bands for the front and 4 bands for the rear). Once I put these parameters into the processor's memory I was able to recall them through the 7949's remote control.
