    Is it a "squeel"? Alternator whine (changes when motor is reved?) In theory, NO high frequenct should be coming out of subwoofers as they play low frequency, unless your crossoveris set to high. Let me know.

Sounds like it could be a warning sound that indicates either a short or a bad connection and is tripping the safety warning. check all speaker terminal connections and connections on the amp to make sure there is nothing loose or touching

High Pitched Noise Coming from Sony STR-DH510 LCD Screen - how to fix?


Hello
The problem is with its backlight inverter board. there are some step-up transformeres [small ones] fitted on board. If any one's core bacome loose this fault will occur. Just open the TV and listen to which one makes hi-pitch noise. Replace it, if you can buy it from the electronic market at your town. In most cases, the inverter board needs replacement.
This board can locate on the right or left side of the panel, fitted vertically.

High pitched noise red light blinking


A high pitch noise comes normally from blown capacitors from the motherboard or the power supply. But mostly high pitch noise comes from power supplies.

You could have to open up the power supply to see them.

Verify if it is the case and replace the faulty part.

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.

Jl audio 500/1 amp low ohm light at high volume


I would try running the subs in parallel. Pos to Pos Dual Voice, Neg to Neg Dual Voice. Then Run + to + stereo - to - stereo on both channels.
So you have + and - running to one channel and + and - running to the other channel.
Also your LPF filter could be set too high.

High pitched noise comin from sub


if sound also goes away when throttle is released and sound returns when throttle is pressed down, then you have engine noise from car engine electronics. In older cars, this was quite noticeable when the cars had distributor caps. The electrical noise caused by arcing required for the spark plugs could be your issue. It is resolved with a noise filter which gets wired inline leading to your in-dash deck and power amp (if you have one). The filter can be found many places including Radio Shack and Crutchfield.com. First find your total wattage draw for each component of the sound system (deck and amplifier), then divide by 12 to get current draw through filter. Purchase that size filter or larger.
