Question about Infinity SW-12 Subwoofer
It could be an internal "cold solder joint" however, if your lucky, it may just be dust buildup on the control pods and switches. Radio Shack sells "Tuner Wash" which will clean potentiometers (volume controls) and other electrical contact points. It's an inexpensive "try". Pull the volume and crossover knobs and lightly spray down with the wash. Let it set 10-15 seconds then move the control pod back and forth. Turn it back on and see if it's better. Hope this helps
