Re: girl has no idea lol
It's likely the amplifier but defective speakers or having speaker wires shorted to ground can cause strange problems also (depending on the way the protection circuit responds).
Disconnect the speakers from the amp and connect a speaker that you know is in good working order. Use a speaker that can handle a lot of power and be ready to switch the amp off quickly or disconnect the speaker wires from the amp in case the problem is in the amplifier (you don't want to damage the test speaker).

Since you have said the speakers make this sound when "turned on", I'm going to assume there's some form of power amplifier attached (internal, external or otherwise). Based on the minimal information provided here, this simply sounds like the normal reaction of a speaker when the amplifier is turned on. In short, an audio speaker is a type of "transducer" and when power is applied (thru some form of amplifier), the cone reacts to the power surge and causes a thump, pop or other noise. Turn on your TV for example and you'll usually hear a small pop from the speakers...and a larger/more powerful amplifier is likely to make a louder noise. Without further information, in most cases this is quite normal.
Assuming there is an external power amplifier, my advice would be to turn the volume on the amp (regardless of whether there's a receiver connected) to 0 before turning the power on. If it still makes such a noise, it's possible the volume control of the amp may require cleaning.
Have you tried different speakers? If a speaker has a short, it will draw too much current from the amp and pop the fuse. Also, does the amp pop a fuse on idle, or just under load. What is the gain set for?
If the amplifier itself is making the popping sound I suggest you disconnect it immediately, as it could be an electrical short within the amp. If the popping sound is actually coming from the speakers, it could be due to a crossed wire, blown amp channel, or blown speaker. If you posses the technical know-how, you can test the amp channel and speaker by connecting a different speaker to the channel responsible for the popping sound. If the new speaker makes the same popping noise then it is most likely a blown channel. I hope this helps =)
make sure your speakers are wired to the amp with correct ohm load, turn gain, bass boost all the way down on amp, zero out your equilizer on the cd player and turn it all the way down then start raising volume on cd player., when u can start hearing music thru the subwoofers adjust the cd player volume till the sound from your subs is at its peak without any distortion. then start raising the gain on your amp till you are happy with the sound. It gives you the optimal signal strength coming from the cd player and the smoothest sound.
Make sure the speaker wires are not touching at the back of the receiver or at the speakers. Make sue the cable(s) connecting the two is not damaged or shorted. If the wires are ok then the amp/receiver is the problem. Possible bad capicitors are the problem in the amp.
You might have mistakenly changed the Equalizer Presets in Volume Control Panel on Tray ICON which is located near to Date & Time (Right Bottom Corner of the Screen). change the presets to Rock/Pop you can get clear output of your choice.
Thanks & regards
turn on the amp and you know that the amp is good and you hear nothing
1. paralell wiring on speakers that are the wrong impedance very often will silence speakers to a eternal sleep along with that amp.
2. 4 ohm speakers mistaken for 2 ohm and are 8 ohm speakers mistaken for 4 ohm, the amp sees this load and it causes a overload on either side of the amp internal filter
( that's what makes the "pop sound") amp pops inside, literally makes a "pop" sound
you get a no sound
