To actually answer your question, yes, a surge protector is just fine. Don't worry about it.
OK to plug sub into a surge supressor......
I have dirty electricity, my wife is always drying her hair, the voltage swings produce pops in my Rhea subwoofer. I have plugged it into a surge supressor that I use for my computer, and it has solved the problem. HOwever, will the supressor also limit the amount of power the subwoofer amp is trying to draw? If so, is it worth getting a dedicated 20 amp line just for the sub and the rest of my rig?? thanks......Mark
