How can i tell if there is a problem with my subs verses my amp or if its the wiring......My subwoofers seem to stop working and start working randomly....it makes no difference how hard they are hitting, or how loud i have them....They will stop working and then come back on randomly. Has anyone ever had a problem similar to this? I am running a 500/1 JL Amp (Brand New) And 2 MTX Thunder Subwoofers (new). They ran great for the first couple months, but the last month I seem to be having more problems with them.
