Hi skullkeeper,

the problumim having is when i hook up my spekers to my receiver left turmenals A or B it makes the speakers sound blown but the right sounds fine. now both sides are starting to do it.

A and B come from the same amplifier.

also befor the warranty was up i sent it in because if the volume nob got turned by hand or remote it made a staticy sound they sent it back but they never fixed it. now that the audio is coming out sounding blown the nob dosent seem to make a staticy sound.

Is it out of warranty now?

Your fault may not be the volume control. It could be bad relay contacts that connect the speakers, or bad solder joints. Do you play it loud enough that it cuts out?

I moved your thread to the Solid State section where it will get more attention.

Hi skullkeeper,
It is possible that the speaker leads touched if they were not dressed properly. If you have a chip type output, it may be damaged. Transistor (or discrete output stages can be repaired, chip types need the entire chip replaced).

What is the model number?

[skullkeeper]

its KR-A5040

the wires were kinda cramed in the red/black spring speaker turminals

Hi skullkeeper,
It only takes one strand of copper to ruin your day.

Hi skullkeeper,
Okay, start by troubleshooting your stereo. Figure out weather you have cracked solder joints, bad relay contacts or distorted audio.

Do you have a 'scope? A good DVM?

[skullkeeper]

ok ill check what i can. sorry what is scope ,DVM? iv got a Multimeter.

Hi skullkeeper,

sorry what is scope ,DVM?

A 'scope is an oscilloscope. You can see what waveforms look like related to time.

A DVM is a Digital VoltMeter. A good one is usually a Fluke.
