Question about Audio & Video Receivers
SOURCE: Losing volume on channels
I am afraid not. That crackling is a component in one of the solid state amp circuits starting to fail. These are all soldered into the printed circuit board. This could be a difficult repair to find an intermittant component. Depending on how old the unit is and how much it cost will factor in on if you have it repaired or not. Rule of thumb is that if the unit is two to three years old and cost less the 200 to 300 bucks you should not invest more then 100 to 150 bucks into it. Good Luck

The general fault come up with the AV recievers is:
My A|V receiver says, "OVERLOAD" and shuts off, what should I do?
Poor wiring connections, bad wires or a bad speaker may cause this. As you increase the volume, you will increase the amount of current you are drawing from the receiver. To troubleshoot this issue, try the following:
1. Disconnect each speaker wire connection. Inspect for any frayed or damaged wiring and replace it.
2. Check the impedance of the speakers; make sure they are properly rated for your stereo. In most cases, they need to be 8 ohms. Only a few Pioneer receivers will support lower impedance.
3. If the problem still continues, try these steps:
1. Turn the receiver off.
2. Remove one speaker.
3. Turn the receiver on.
4. Increase the volume.
If the receiver overloads, repeat steps 1-4 (selecting a different speaker each time). If you disconnect a certain speaker and the receiver no longer overloads, have this speaker checked at a service center. It could have a bad speaker component, like a tweeter, sub-woofer, or even a bad crossover.

There is a disparity in the impedance of the speakers and the outputs of the receiver - the speakers are too weak and they act as a short , damaging the amplifiers , hence the Protect status being engaged.
Trying to run the receiver with a wrong set of speakers has probably damaged it. Get a correct one and try the setup only with it, if you're lucky it was just the safety system cutting the output.

Something doesn't add up. You mention two connections to the speakers - CA-9335 and a "simple jvc cd player". Is that true? If so, you might want to UNconnect the CD from the speakers and run it into the receiver where it belongs. An amp isn't designed to share the load with another live device; or even have electrical contact with anything BUT speakers.
Did you actually find documentation that supports this hook-up? Or just winging it?
