actually it could be the alternator, or starter. or you could have a bad ground, or open loop in your power supply line. i'll need more info, but it sounds like a ground issue.

well most newer cars have the anti-theft,vss,or other BS, wired thorough the radio harness for whatever reason they felt. however they now have by-pass modules for most aplications.

check this out. If you take the factory radio face (rack of buttons) in a 01 ford focus the car will not start, or if you turn the car off, and push the volum knob to turn the radio on for one hour then lock the doors from the remote, the remote will no longer unlock them without being re programed(after you break-in to pop the hood and cut power and then re-program)....fewww!!

you must buy a wire harness connector from best buy or another dealer with knowlege and parts available / ps with this connector you just connect the wires from the radio to the connector following the color diagram and then snap on the connector to the car plug and it will work..

that model is for an automobile, if you go to the website link I am posting look for your model of unit as you used to be able to download owners manuals as well as wiring directions for free but in the past you had to join the pioneers web site

go to any store that specializes in car audio, they will hAVE AN ADAPTER HARNESS TO MAKE THIS WORK.

check the wiring loom & pins in the plug.

there is a fuse in the unit as well so check that as well.

ok maybe i am not understanding what you are trying to do .if you are looking for balance you found it balance is front to back and side to side. if you are saying the volume wont change you might have one rear hooked up to the front and one to the back. this is most common on cars thatare hard wired "no harness"double check the way you ran the wires good luck

Get to the set-up menu by pressing the source button until just the clock is displayed, no music just the clock. Now press and hold the "func" button until "Menu" appears. Now scroll thru the various items using the up & down or the side to side buttons. I believe you will find the item for US or Europe or like Alpine reads Area 1 for US and Area 2 for the rest. Good luck.. Mark

Push the menu/sel button, select bal/fad. Pioneers use the same adjustment for balance and fade. push side to side for balance, up and down for adjusting front to rear

I think this will help;

If this link does not work. Let me know and I'll lead you to the site.

buy the "jumper kit" from walmart, its like 12 bucks ge the GM 1999 to what ever year, match the colors of the wires, plug in the antenna cable and your good to go.

It may just be a bad connection where the harness plugs into the radio but it sounds internal. The trim on the dash in front of the radio pulls off just be gentle. Working from the right side to the left grab the trim panel with your hands you may have to use a small putty knife to lift it off the dash enough to grab it. Then you can take the screws out on the sides of the radio and pull it straight out. It may just have two plastic clips that you have to squeeze not screws. Getting this fixed may be to costly. You can find these radios on Ebay for pretty cheap and they are easy to replace. Less than $50. Good luck I hope this helps you.

you need wiring harness for your truck to the radio go to your local bestbuy or car audio shop then follow color coded instructions for the wiring

If you changed the rear DIN cable to AUX with an adapter, you may need to turn the AUX/Changer feature on. Pioneer is not a brand I sell, but I am pretty sure you just go through the menu to turn it on. If you can't find the option in the main menu, try turning the deck off, and accessing the menu there.

you need the stereo keys and if you don't have them witch i believe you don't have them then you have to take it to a shop or if you do have the keys then remove the small bezel around the stereo then insert the keys on each side of the stereo then just pull and it will slide right out

That is the symptom of a faulty selector switch. That's causing automatically switch up from CD to tuner station. Replaced the selector switch with a new one, so ks normal again.

Good luck;

Don't forget to rate:

MOST OF THE TIME THE CONSTANT CAN NOT BE HOOKED UP TO THE SAME WIRE AS THE POWER WIRE, U SHOULD HAVE A WIRE IN UR HARNESS THAT IS YELLOW USE THAT WIRE, IF U DONT FIND A FUSE INSIDE UR CAB USE THE FUSE AS A CONSTANT POWER LEAD BUT PUT IT ON ONE THAT CUTS ON WITH THE KEY.

pioneer head units only distribute like 200 rms or so to the speakers. you might have to find a blue maybe even blue with white striped wire and nick it just enough to tie your amp wire around it. tape it up and see if it works.

Sounds like a grounded speaker, disconnect each speaker and see if the sound comes back on through the remaining speakers connected. Its sounds like it is just in protection mode from a chssis ground. I hope this helps!
