for some itme now, the subwoofer always coughs, rarely hearing the normal sound. I went to the retailer but they could'nt fix it. It seems that there is a problem with the speaker itself and not the amplifier. It does this without being connected to anything else, so it is not the source.

It could be a bad or bad capacitors. On the power board. Capacitors look like soda cans small soda cans. Good ones will have a flat top. Bad ones will have a biging top and sometimes fuilid sedimant leaking from them..
Hello there..Thats normal only if your sub volume and the pre amp is turned up..Your amp is the cause of the speaker jump..Turn amp volume sub level down a few and check your wire from sub to amp..If all of that is good is a normal operation for pre amp warm up in sub if level is turn to max..Try unplugging amp freom sub then turn sub on stand alone(just sub outlet plugged in and no wires from base amp plugged in..If sub stops the its the amp making the problem..If it still is there then the pre amp is either dusty on inside or the outlet plug that it is plugged in doesnt have a good ground..Hope these help to solve your problem..Have a great day...
I had the same chirping issue with the sub. I found a document that talks about replacing the C5 capacitor for a 47mfd type instead of 470mfd. This solved the chirping issue however I still experience an intermittend issue with the power on indicator flickering off and on. Anyone hear of the fix for this?
Hello, Jesse. I doubt I can help, but there is at least one SIMPLE thing you can try - with maybe a 10% chance it wil return your unit to normal:
Unplug the unit for 30 seconds, then plug it back in to a DIFFERENT outlet.
Oh, yes - there are NO fuses or other "reset" devices.
I'm sorry I couldn't offer you more help.
