Re: My subwoofer atarted making deep humming sound, then...
The voice coil of your woofer is off centered and shorting on the armture causing the speaker to draw too much current. The fuse blew thereby protecting the output stages of your amp. Replace the speaker.

Try removing the wires to the subwoofer and then hook a "aa" battery to it and see if it makes a pop sound..this will tell you if speker is ok...if it is then I think the amplifier sectionj for the sub is what is blowing the fuses...you are probably right..it looks like it's a 1 A fuse...but if it's blowing right away..it may be circuitry related
Some kind of semi-conductor in either the power supply section or the main amp has failed and acting like a piece of wire, which is why the fuse is blowing. You might want to look around for damage or burning. If it's a transistor or diode that has gone an Ohm Meter will show it up well. For when you put the test probes on the terminals of the suspect part, it will be like you had touched the probes together!
Check your speaker settings on the main menu of the receiver first. If you still have an issue, post a comment and I will help you troubleshoot some more
kindly check out maybe the fuse was already explode...check the connections specially the coil of the speaker using a multi tester....thanksss and gud luck
Sounds like an inadequate ground wire in the signal cable. You may have to replace the cable between the reciever and bass module. It also, however, may be IN the bass or reciever module.
The humming sound usually comes from the DC supply that is not filtered. The a/c converted or changed to DC needs to be "cleaned", before going into the ckt. Usually the capacitor and resistor network go bad, maybe causing the fuse to open. Even if you replace it, u may still have the "humming" because the circuit is still bad. If you know how to look at the capacitor, resistor,or coils AFTER the diodes & replace the damaged part, u should be good!
Check the circiut board for any blown capacitors. Sometimes it's that simple as replacing a capacitor. But then again, what is causing the capacitor to blow??/ Hope this helps.
