I have had my h.u. For a few months now a Kenwood excelon KDC x998 and have never heard the cd skip with one 12in woofer. This past weekend I installed 3 SQ hds3s. The 1st couple days I didn't play them very hard , day 3 and 4 I cranked them up and my audio control epic center was saying a 147db no skipping. These past couple days I can't get past 141db with the h.u. Skipping bad. It even does it around 137 138 moderately. Does anyone know what all the sudden is causing the bad skipping. Do I need to have my h.u. serviced. Did something rattle loose? If it is the h.u. And will always have problems with this model Does anyone know a good unit that has DSP built in that won't skip? I have also heard drops in voltage will lead to skipping but I have completely upgraded the electrical and if that was the problem why didn't it do it the days I had no issues. I have been slowly building this system over the last few months and it's disappointing I can't even turn it up now. If it is this headunit I'll be quick to get something different as long as it has most of the features the Kenwood I have now has. Thx for any input
