You didn't indicate what car your radio is in, whether the car has factory amps that the pioneer is integrated into or bypassing, or if you're using the radio's factory amps to power the speakers, or if you have external aftermarket amps fed from the radio's preamp outputs. So with the lack of information, it's hard to say for sure what's going on, but I would suspect either you have a radio whose internal amplifier is dying, or your car has an internal amp that's being overdriven because your pioneer's internal amp is providing a powered signal to your car's factory amp which should never be done. There's too many directions in which to go to troubleshoot this issue because you haven't said anything about the make and model of your car or it's current sound system, so I hope I've given you enough of a foundation to point you in the right direction.

SOURCE: Is this considered clipping in marine boat stereo help!!!!

if your radio is puiing more power your ground might not be good enough, use the same spot but remove the ground and rough it up a little on the base with some sand paper or add a metal o ring to get a better ground.

SOURCE: i have a pioneer DEH-P3000

Hi nhmteam. I have the solution for you: 1. With your DEH-P3000 turned off, press your FUNCtion button. It's a tiny button towards the upper right of the faceplate. Hold it down until you "ALARM OFF" or "ALARM ON" on the display. Release the button. 2. Press the FUNCtion button again and you should see another feature. I don't remember how many features you need to cycle through, but keep releasing and pressing the FUNCtion button until you see "M-CD ON" on the display. If you miss it just keep going and eventually it will come back. 3. On the right side of your faceplate there is a button with 4 arrows. You will need to push the up or down arrow until the display reads "M-CD OFF". If your display already reads "M-CD OFF", kip to the next step. 4. Press and release the FUNCtion button again and you should see "AUX OFF" on the display. Again press the up or down arrow until the display reads "AUX ON". 5. Now, turn on your unit, then press the INPUT button until the display reads "AUX". You are now ready to use your iPod in the way you always did. Keep these instructions for the future since I believe every time you disconnect the unit from the battery the unit will reset itself and disable your iPod cord. Best regards - TomR

SOURCE: got an aux cord to plug my ipod in, doesnt switch to "aux in" mode

According to the manual, you need to "enable" the AUX 1 or 2 thru the initial settings menu.

Press and hold the SRC until the unit turns off. Then press and hold the MULTI CONTROL (knob) until the Language appears. Turn the knob to cycle thru the options, select AUX 1 or 2 and press the knob again to select ON.

After selecting them to on, power the unit on and press the SRC to cycle thru the sources to find AUX 1 or 2.

The owners manual is here if you need it;

SOURCE: no sound out of subs

Check the ohm of your soeakers again. If it doesn't say 2 ohm thats the prob. Keep in mind that 2 ohm can be any where from 1.7 too 2.3 but any reading on you DVOM that gives you two decimal places is also wrong. i.e. 2.17. This would mean that you have a woofer shorted.

If thats not it and you have already fixd a ground then use your meter to check the ground; to do this set the DVOM to ohms and touch one lead to a true gound, by that I mean scratch the paint and primer off of a spot you can hide untill you see bright mirror like metal. Then disconnect the ground wire from the amp and touch the other lead to it. You should read anything from 0.3 to 0.1 any higher and your ground isn't that great.

If thats not it, The only thing left is to hook the amp up out side of the vehicle away and not connected to ANYTHING that has to do with the car. Get a battery and a diskman or a playstation, anything that can pass sound out of RCA's (Maybe even a diff radio if poss). Hook it up. If it works its in the car and let me know. I'll tell you some more to check, If not its the amp. Good Luck

Not getting any sound from my i-pod Pioneer AVH-P4050DVD


I had the same problem with my Pioneer AVH-P4050DVD

Radio and CD worked fine

DVD would play and I could hear the audio but no video

USB and iPod. It would connect and I could brouse, select and play songs but I would not get any audio even though I could see the track playing, finnishing and moving on to the next one (very frustrating).

Front Aux (Aux 1). I could turn this port on to audio, select it and plus an audio sorce in but no audio would come out.

The solution..
The Pioneer AVH-P4050DVD is odd and different from most other pioneeres in that it has two earth leads that both need to be grounded (2 in addition to the handbreak wire). I had insalled my unit using a toyota - pioneer wireing adaptor I bought from Repco. This adaptor only grounded the wire coming from the corner of the plug (opposite the battery wire). The second earth is located becide the first earth, opposite the ignition wire. If you google pioneer 16 pin wiring diagram it might call this pin BGSENS (pin 13 in the attached photo). With the wireing harness I had this pin was not connected to anything. Once I grounded the second earth (soldered directly to the first earth) everything worked.

Good luck. Hope that helps.

Avh-P2400bt In a 2002 Jeep Grand Cherokee NO SOUND


Plug the old head unit in again and test the wires when the radion is on. There is obviously an amp turn wire in that harness that needs to be powered up. It will be a wire other than the yellow (12 volt constant) and red (12 volt accessory).
Also, the green parking wire can be used to watch movie when the vehicle is in motion. It needs to see ground in order to work but, connecting to constant ground won't do. You need to put a two wire toggle switch on it and the black ground wire and run the switch somewhere that easily accessible when driving.

Unit won't turn on....


There are several surface mount fuses and the flexible pcb is also a suspect, don't attempt to repair this unit yourself unless you have experience if not you will end up doing more harm than good.
