[QUOTE="KEVIN C., post: 3655464, member: 581911"] Prior to using imprint to tune my system, I set the gains on my Alpine PDX 4.150 at approximately 1/3rd of the way up for the mids and highs (set using a DMM for 150w x2). Then I turned down the gain on the bridged output for the sub to match the mids and highs (1/3rd up). The instructions recommend setting the subwoofer gain at 1/2 or less. Set the sub level on the 9887 at 0. Then I Let the imprint do it's thing in all 6 positions for the front soundstage. I chose the linear curve and the reference curve to save on the 9887 as curves 1 and 2. Once the imprint had done it's thing, I turned the gain back up on the sub bridged output to ~3/5's up on the dial. This is where the gain was set for 300x1 on my sub using a DMM. I also turned up the sub level to 15 on the 9887. To my ears after the imprint sound tuning, this outputs clean bass which you can feel while also blending seamlessly with my mids and highs. Spectacular sonic difference compared to what I was able to do tuning manually. Hope this helps... remember your results may vary. [/QUOTE]
