Can't turn on "A" speakers and "B" speakers at same time

This is a self-protection mode protecting the receiver from low impedence / High Current on the speaker side. Given that this is an exercise stereo and it may be turned up I would recommend purchasing a second amplifier to run the second set of speakers. Obviously I would recommend one that you would be able to add and remove before and after the class.

I have a recently purchased RS 2664 RCA shelf

If the wires got crossed and/or touched each other at all - that could certainly damage the amp(s).
Also - if the system is not made for extra speaker - that would change the ohmage - and that could aslo damage the amp(s)..

Or maybe the system designed to protect the amp(s) was damaged..

Hope this helps !!
Please rate me good ;o)

My shelf system says protect when i turn it on & i don't know if thier's a way to reset it. model#ca-mxgc5

The only way to reset these units is to unplug it from the wall for about 4 to 7 days, then plug it back in and see what happens. They do not have a reset button, and it takes a while to reset because they have a capacitor in the microprocessor circuit that holds the voltage for it for a good long while. The type of capacitor they use acts much like a battery and takes a long time to drain.

Your unit is in the protect mode, and it happens when there is a blown channel in the amplifier circuit or a power supply failure. The only way to determain exactly what is wrong would be to troubleshoot the unit using the proper tools. If you have a multimeter and soldering equipment you may be able to do this yourself if you have some experience with electronics. If you do not, you really should just take it in for repair at an authorized JVC service center. They would have the schematics and ability to troubleshoot it properly.

If you have the tools needed and would like to try it yourself just let me know and I will be happy to guide you thru the process. Please be aware that troubleshooting electronics by somebody with little or no experience with it can often result in more damage than you started out with in the first place. Having said that, if you are willing to try, I am willing to help. But if you end up with more damage than you started with you can not hold me responsible, I have warned you

I work at an authorized JVC repair center and have repaired many of these units over the years, so you would not be getting help from somebody who doesn't know what they are talking about. So just let me know if you want to take a crack at it.

My cd trays are locked and wont open on my jvc stereo model #Ca-Hxd77 system #Hxd77 and i dont know how to unlock it.

Most CD trays have a small hole at front for you insert a straightened paperclip about 1-2 mm inwards. This allows release of tray when power is off. I assume this is what you mean by mechanically locked, not locked by software.

Hooking up a turntable to a JVC XM-J50 Via AUX port.

You need a phono pre-amp for magnetic cartridge. This will amplify the magnetic cartridge output from its low level to line level which is required for your amplifier.

This can be bought at most audio-file type distributors and stores. There are different quality levels in these depending on how much you want to pay.

My stereo says "protect" when it comes on then it powers down

The protect messing indicates that a problem was found in the final output stage of the amplifier. To prevent further damage, the system shuts down. The typical problem are the output transistors which can fail. They are usually shorted. Expect a parts cost between $15-$40. Add in the local labor rate for the total repair cost.
