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.

2003 bmw 325i makes buzzin noise after driving for half an hour on a warm weather


If this is after you stopped the engine , is is possible the Cooling Fan is still powered for a short time to cool the system even after you left the car.
In some rare occasions ( VW vr6 p.e.) there is also an electrical water-pump to keep the cooling going after stopping the engine.

I have a jl audio w3 that doesn't play or make any noise. I bought it brand new, never had been installed. Pressing the cone feels smooth and precise, so there is no signs of the coils being burnt out. The...


Id say take it back to where ever you bought it from and get an exchange. Have them test it there and see if it works. I have a JL W6 and have had JL's for a long time.To hear of something like this with a new JL is very rare. Just may be some kind of defect. Bring it back, get it tested and go from there.

Car subwoofer makes deep bass when i hit the gas.


there could be 2 reasons why, first make sure your power and remote wire is ran down one side of the car, second make sure the rca jacks is on the opposite side of your alternator, make sure they are that way, this will work, if noise is still there, then you may need and inline noise suppressor. but you shouldn't

The microwave would appear to be working - light is on, makes a noise like when it was fully operational, timer counts down but when food is removed it is stone cold


there are a few things that can cause this, 9 out of 10 times, its a magnatron and HV diode failure. they will need to be replaced, most manufactures have a 5 year warranty on the magnatron which is the more expensive part. $100-$250. you will need someone to take the whole unit apart to replace these. rarely it could be the power relay on the main control board or a bad door switch. ( there are three) you should have someone trained diagnose the unit before you buy parts. half the time its cheaper to buy a new microwave. estimated total cost $200-$350

That's a shame. Does it not read CDs or not recognized in BIOS or Wirndows? Please elaborate.

Cerwin Vega V-10S Subwoofer doesn´t sounds good


dear "rai17"

This, to me, is most likely the voice coil inside the driver rubbung against the yolk plate, or possibly the spyder slapping the metal plate underneath it, or the amp-(if it has one?) getting tired. this can occur from poor build quality, or playing the subwoofer too loud. depending on how much it cost you, you may want to get it repaired(voice coil re-alignment or something or new amp). But the way it seems, it is probably the driver itself. subwoofers get looser as they break in. This one may have been over-broken....sorry

I hope this helped clarify what is happening!
