Klh powered subwoofer model ASW10-120B... when you plug in to power... it makes a loud buzzing/humming noise


I would check the caps on the power supply. They are rather large electrolytic capacitors that will look like they burst and/or leaking. When these die, the caps ground and the sub will make a loud buzzing sound. If you are handy with a soldering iron you can replace them yourself. Replace them with the same voltage or a little bigger and same with the size.

If the cap. says 16v 4700pF on it, for example, a 20v 5300pF or a 16v 6200mF cap. will work for this application.

New fuel pump in 01 blazer making humming noise


No Fuel Pumps do Humbbbb, and some loudly, although you probably left the rubber/insulator for noise absorbtion off the pump. The new ones usually dont come with this, unless you get the whole assembley. It's just a rubber piece that wraps around the pump motor nicely and ablorbs that Hummbbbb.. Time to drop the tank again. I hate when I do that..

Radio shack noaa desk scanners squelch sound unit wont scan


If the squelch is on, there can't be a loud noise. Either the sqelch is completely off or you are not tuned to a station. NOAA broadcasts are continuous, not intermittent

My sub hoover cant play but just making some noise


You need to be much more clear, and provide a lot more detail if you want help on this issue.
What brand/make/model sub woofer? is it a powered or passive sub? what is it hooked up to? how is it connected? what is the audio source? what sound is it making?
Please be specific in all details.

Rockford sub squeaks


Hello markwasicki,

You did not specify what type of enclosure the subs are in or if they share the same airspace. But the sound you describe sounds suspiciously like the enclosure is at fault and not the sub itself.

Remove and reverse the subs in the box and test for the noise again. If the noise is still produced on the same side of the box, it's the enclosure. If the noise follows the sub, then you have a problem with that sub.

If the box is making the noise, and it's a ported box, you probably have "port noise". If it's a sealed enclosure, you could have either an air leak or flexing noise. In either case, repair the enclosure or put the subs in a new one. If the sub itself is making the noise, there probably isn't much you can do. Most likely some part of the voice coil assembly is touching where it should not.

Hope this helps.

Woofer making horrible noise! HELP!


Think as an expert... Probably from my experience repairing woofers etc... the cone (1) or the spider (2) isn't well glued onto the woofer skeleton(or both???) The woofer cone must be absolutely centered or else you will get those clicks in low frequencies(you also get them in higher frequencies but you can't hear them!) I must say that it is very difficult to repair a woofer by your own. I suggest to return it back where you bought it and take another one (i suppose that you have a guarantee ha?).
