Hey man, just wanted to give a quick thanks and an update. The system has ended up sounding pretty awesome. Moved the tweets on the comps right next to woofer and attenuated to -6db (might go back to-3)Depending on the music, comps are hp'd at 125-160 with 6db/oct slope, rear 6x9's hp'd at 80-100 with 6db/oct slope with 1 layer of masking tape over the tweeters. Sub is lp'd at 50 with 12db/oct slope. I wish I could lp the sub at 63 but it starts to resonate too much. The deh80prs has great sq and imaging options. With the position options turned off the overall power of the system is amazing, with it set on front left the stage is down by my knees and the bass is right in my lower back. The only issue I still have to work out is 80-100hz resonating with bass tones in the doors panels. I COMPLETELY deadened one of my doors and it helped a lot so that will be another project down the road when i get the $$$$$. Thanks again man!
