Where can I get speaker wire for a jvc compat component mx-g9

You can't, it is an antique. You can get a reasonable Bluetooth speaker for $20, or if you want to something to fill the house with concert quality sound, a Bowers and Wilkins Bluetooth speaker. I have four of their products.

JVC MX D402T Instructions Manual

If it has a bi-amp, you can connect the speakers to it. By the amplifier, if it's a stereo with bi-amp, be sure that it has at least 400 watts and up in order for the speakers to turn out great, if a receiver like a integrated amplifier, it may have like 2-10 connections, you can connect the speakers all together if it has more than 3 connections, if below 3, you may need to take the speakers apart and make it 3 way by connecting one wire to the tweeter, another wire from the tweeter to the main or mid speaker then one more wire from the main or mid speaker to the sub.

First check that the speaker wires are not shorting, if okay! the problem is in the audio output stage of the receiver, the protect mode comes on if a load is detected.

Is there a problem or are you cabin-bound and really bored?

Or do you want an instruction manual?

If the latter, go to http://www.retrevo.com, register and download it for free. I found it using "JVC MX-D602T" as a search.

If protect is coming up on the display, it means the system is detecting a short somewhere on one of the speakers and so is turning the amp off to avoid damage.
Check all the connections at the back of the amp to ensure they are not shorting, and at the back of each speaker, if nothing is found there, check each wire for damage (like squashed or rodent damage).

The word PROTECT appears because there is a short. It can be in your speakers, try running it without the speakers plugged or check to see if your speaker wires are touching (shorting).
If it still says PROTECT, its because there is a short somewhere in the system, probably from the output section.
The system does this to prevent anything from damaging the electronic components inside.

sorry no but try to find the power wire and then turn it on then try to listen for sound to out of the speakers well that's what i had to do i did it in a half hour im sure you'll figure im only 15 and i did

Open it up and check for internal fuses, if any in there, test with a wire, bulb and battery. The values (voltage and amperage) will be on the fuses or next to the fuse holders. Also look for any obvious burnt components like diodes( small bleck tripods) and capacitors(coloured "tubes" with a wire at each end) and resisters(like capacitors but with coloured stripes on). Obviously it will be cost dependent.
And most important UNPLUG BEFORE OPENING and be cautious as capacitors may be small but they can hold a very high voltage for a long time.

this is easy to do and you musnt be scared.first find 12v permanent ,then 12v switchable,ground ,ignore electric aerial which is normally blue or yellow use a piece of twin flex connected to battery and flash speakers so you know which is where,good clue is speakers have same coloured wires but one has a black or white flash through it .And away you go music
