[QUOTE="AlterEgo99, post: 5946656, member: 610253"] OK, OK. [IMG]//content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif[/IMG] One of the biggest gripes with Imprint is how it can mess with your bass. If you follow the manual and either turn the gain "below normal" or all the way down, yes, you bass is gonna be affected after running the software. Plus, the documentation is not too specific about setting the crossover and subsonic filter/bass boost if you have that option. So, here's what I do based on my Alpine PDX 1.600 (also note that is based on my CDA-9887 HU - not sure what other Alpine models use this same software and their (HU) RCA output voltage may differ): Gain Setting: Right in the middle, dead center. Input Gain Selector Switch: 0.1V-1.0V X-Over Frequency Adjustment (LP Filter): Dead center, 100Hz Subsonic Filter: Off As for my amp driving my front and rear component Polks (Alpine PDX 4.100): Gain Setting: Nominal (dead center) Filter: Off X-Over Frequency Adjustment: I leave these set to the lowest freq. my front and rear woofers can reproduce. As for the HU itself, I make sure the Bass, Treble and Sub settings for each source is set to flat (0)...for the Sub setting I make sure it's in the middle, or 7 or 8. I'm not 100% sure it matters, but just to be safe. I then run the program for left front (that'd be for the driver position - me!) and I then make sure that all 6 locations are measured. This will take about 40-45 minutes to complete. I then download both curves. Once completed I had to adjust the gains on my Alpine PDX 4.100 down a bit but left everything else as is. For my PDX 1.600 I set the x-over to about 140Hz and the subsonic filter to 15Hz. I also crank the gain to about 3/4. I have measured the AC output at the speaker outs on the amp and about 3/4 volume (which is about as loud as I can tolerate) and it gets to about 24V max at some real deep bass points with some reference music.

I'm happy with the setup, the soundstage is perfect and the freq. curve really gets nicely smoothed out.
