Hey guys, it's been a while since I posted, but here goes.
Last year I had some techno music up really loud on the weekend. I had an old Pioneer amp that was feeding a live signal(NOT line-out, but actually speaker wire) into the inputs(They are designed to accept line-level or speaker-level signals) of my JBl 15" Sub. Well, I turned it up louder and louder, and after a while I heard a popping noise. So I shut everything off and let the sub rest for the night.
At first everything seemed fine and I would occassionally hear a "pop" from the sub during quiet or loud playback. As time went on, the popping noise became more frequent. At this point, if I even turn the sub on(even if NOTHING is feeding it a signal to reproduce) it makes a continuous "pop-pop-pop-pop-pop" noise. A friend of mine who is an electrical engineer told me this is called "motorboating" and is often a problem with a diode(?) or transistor going bad in the power supply. Do you guys think this is the case? What do you think it will cost to repair the sub?
BTW, it is in the repair shop right now getting an estimate...I just want to know what is a reasonable estimate for repair. I hope the problem is simple to fix.
