Subwoofer thumping when turn on

I have a old Mirage PS-12-180 power subwoofer and recently it gives a continuously popping noise by itself when power on. The popping will becomes very loud during audio and video playback. I wonder what could be the problem and is very expensive to get it fix
Thanks

    The subwoofer is for my home theater. However I did try a different wall outlet to see if this is the power problem but the problem remains. It just keep " POP pop, POP pop ...after 5 mins power on.

Your subwoofer is not getting enough power, or it is grounding out due to a bad connection. What is powering the subwoofer? You might want to consider buying an AC to DC power inverter and a car amplifier to power your subwoofer. You connect the AC/DC inverter to your amp the same way you would in your car (+) to (+) and (-) to (-). The only other thing you will have to do is run the remote wire to the (+) on the amp. You can buy the AC/DC inverter at radioshack for $49.99, and all you really would need is a 200watt max amplifier and that would cost you about $10-$20.00 for a cheap one.

What causes motor boating with this subwoofer


Sometime an amplifier becomes a victim of feedback (or oscillation) within itself. This would normally be caused by a failed component; usually a capacitor.

On high gain amplifiers, poor wire routing can also cause feedback, or crosstalk between channels.

The amp might also have a power supply issue. The voltage regulation might not be good enough to keep the amp functioning properly.

Popping noise with hissing sound after long times about 1 hour


If I were you I would start by replacing the biggest (Capacitors) value ones first. You could put an ohm meter on any to see if they charge up when you take them out of the circuit.

Internal damage to Mirage BPSS-210 Subwoofer amp


Something getting hot probably means something shorted out. You probably know that since you replaced the fuses already... . Can you give me some idea of what you do and do not know about electronics? Then I will say fewer dumb things. . When troubleshooting any electronic device, especially amps, open it up and look at the circuit board. Look for burned board and components. Then test to see if the burned/blown component had reason to blow (it probably did). . Often a shorted transistor runs too much current through some other component and the other component blows up. . Another cause, less common, is a shorted cap. . Look at the schematics if you have them, if not, you may have to create one to make sense of it. . Or take it to a shop where somebody does this all the time. The only one here went belly up in the last 12 months... . . About the pots . Try blowing out the pots which are popping with some tuner cleaner. Use with caution, and always with everything turned off and power cords unplugged. . Pots do not usually make popping noises unless they are very old or live in a very dusty place... . I found the manual, but no schematics... http://docs.google.com/viewer?a=v&q=cache:9Doi39-AcW0J:www.miragespeakers.com/images/download/374.aspx+Mirage+BPSS-210+schematic&hl=en&gl=us&pid=bl&srcid=ADGEESjBKgLSTb8wp5SRWIOWd-gE0INdBXbfz5QDNJ_3esye4_R2Q9aKba8cEePSWQWOebeXB9zXnJSelIel2bLSR5q6KExe8MVjOk1zqFKk4K-ruti_797yf1Ig3CIcUNjE49jx8DAr&sig=AHIEtbS6udedt_o6GqL7ALPunU0v3vMvuw . You might be able to get better, more exacting help on the Mirage Forum... http://community.miragespeakers.com/forums/ But maybe not, since the Subwoofer section gets less than one post per month, and the much busier Technical Questions section only has 23 in the last 12 months.

I WANT TO SELL 4 MIRAGE AVS 200 AND ONE avS 100 SPEAKER. WHAT IS THE VALUE IF THEY ARE IN EXCELLENT CONDITION?


There is a set of 4 avs 200's on Ebay for ~$200 OBO so figure around there. Really though these are 10 year old bookshelf speakers so the market for them is pretty soft especially now that Polk and the other big names have affordable bookshelf speakers... (I'm just giving my set to a friend when I move this month)

Sunfire annoying popping noises


If you remove the volume knob, and tighten the nut below, it should take care of the popping noise, as well as any input noise issues. Based on my experiences with my MKII
