I have a Pioneer Premier DEH-P880PRS and my DD9917b on a single IA 20.1 (0.5 ohm) in a box tuned around 35 hz makes it skip at about volume of 30 on the deck, 1/2 gain on bass boost knob, and 1/8 gain on actual amp. These settings are only to show off to friends when they wanna hear it, and I don't ride around with it like this. But I am building a different box tuned to the low 40s (rear fire instead of upfire) that I might use in competitions. But I would need to stop the skipping before I got into any competing.
So basically I want to know if you suffer(ed) from this problem and if you found a way to keep it from skipping, how you did it. In another thread, someone said get a lens cleaning CD and someone else said bend up more metal things .
While you're at it, if you have/had this problem, list up your HU, what you were running, and if you know what you were hitting on a meter when it happened.
