Yes I had one set of components on the front channel and the rear output driving an old sub amp. the Nak head was able to cook eggs in short order. I got an Alpine pdx-r4 and problem is solved with a replacement Nak. Woofersetc was very uncooperative and denied the unit had any issues. They finally admitted the unit would skip when gently tapped. The thing was a skipfest, probably due to the heat. IMHO the head should be able to drive the speakers without heat. So they sent a new unit and wanted to charge me shipping. Not cool since they offer 100% satisfaction guarantee!
