Nice i had the deh-p800prs and it was really sweet sounding. The auto eq was hard to beat. My nak DSP has been a PITA, I think my phone is out of memory. It clears my eq when I restart the car ); But I got a DSP with time alignment for $129. Everybody's price gouging on them now, however. No microphone like pioneer or alpine though. You just gotta do it by ear and rough measurements.
