My jvc UX-D66 B micro system sound is very distorted and crackles when listening to music I checked the wires and they are fine it is the same through aux what could be the problem any advice please


You may have blown the speakers by playing too loud. Try listening with a pair of quality headphones. If the sound is clear through them - then the speakers are most likely the problem.

Popping sound


Check for any external shorting of the speaker wires. Check for kinks or cuts in the cable that feeds the speakers. Also check the posts or socket at the back of the speakers for damage or wiring shorting out. Proactive IT Support PC Repairs Laptop Repairs Custom Built PC Leading IT...

Looking for jvc old receiver model jr-s501


Did you ever find a JVC JR-S501 receiver? I've got one, with a problem. It will play fine for, sometimes half an hour, or sometimes less, and then a loud "POP" sound in speakers. But then will play fine again. Blows fuses on speakers.

My car speakers cut out when i turn my volume to loud what could the problem be i have stock speakers in a 02 chevy truck and a brand new jvc radio


Hello soccer_fr704,

Sounds like the JVC is overdriving the speakers. Most OEM speakers are just not designed to handle more than 12-15 watts RMS and the JVC is rated at 22 watts.

About the only solutions are to keep the volume really low or replace the speakers with ones that can handle the power from an aftermarket receiver. New speakers will make that JVC sound better, too.

Hope this helps.

Scratching (static) noise coming from computer speakers


I foudn this in anther forum:
I have an ASUS motherboard P5E3 Premium. The audio that came with it was the Sound Max audio. I also noticed abnormal sounds coming from the speakers. They included sounds during hard drive activity and also with mouse movement. They were not loud but noticable. I searched all over the web but didn't find the answer. I stumbled across the fix myself. I also have vista-64. In the sound control panel > speaker properties > levels... there is a pc beep slide bar. I noticed that if it is disabled then the abnormal sound went away completely. Problem solved. Hope this helps.

JVC Surround Sound System


The click will be a relay to protect the main amp overloading. In many ways you are driving the amp to hard, unless there is a fault on the main amp which means it can't take the full load that it should handle. One cause of this for example would be a speaker that is either the wrong ohms, or of a lower wattage than what the amp can put out. Or in some cases a faulty speaker, or if the wiring is not good shorts when the speaker shakes when a very loud noise comes from it.
Things to check:
1 That no speaker is lower ohms than the amp.
2 That no speaker is lower in watts (RMS) than the amps total output for that channel it is on. Remember not all surround amps have the same volume on each channel.
It is of course possible to use smaller wattage speakers. But if you have an amp that can output say 200w. Connecting an 80w speaker to it would really limit the amount the volume control could be raised to.
3 Each speaker is working right. Plus all connections are neat with NO possibility of shorting.

If all of these are good then you have a fault on the main power amp. Probably one or more of the output device(s)
