I will try that. I had some problems with my system when I put it in. This is a new house with those pesky arc fault breakers and I had to run two entirely new lines with standard gfp breakers for my stereo/pc components. I also installed two battery backup/regulators. The sub and oaw4 are only hooked to a surge suppressor. Where I had the sub originally was a bass trap of doom, hence the need for the oaw. Thanks for the advice!
