hello chevi1981..what can happen is if whoever installed your system did not run your speaker wires properly eg if they have worn through and touching metal or a screw through the wires ,it can blow the audio ics in unit resulting in no sound.all these high powered units have above ground circuits in the audio stage .to check ,hook up a separate speaker direct to your unit,separate wiring ,if no sound, will most likely be the intergrated circuits..these will have to be changed by a tech as cd players are a beast to work on,also your 2 speaker wires should not touch one another.with your sec code if your have a removable face you may not have a code ,as removing face is your security .hope this helps

Hi check with a multimeter each speaker output, you should have 6voltsa on each connection. if any have either anything other than 6volts then there is a good chance that your power output stage is blown. some unit do have diode protection. so it may not be as bad as it seams.

as a rule you should get half the supply voltage on the speaker outputs.

SOURCE: Have a Crate V50-112.Have had it for 1 year.

Check for bad tube... it HAPPENS that brand new ones fail... USUALLY if they last 50 hours, they will last for the expected life. The bad tube would likely NOT be the main power tubes, as the amp would still run on one cylinder...

SOURCE: I have Imperial 4 speakers

I do most of my vintage audio shopping on eBay.

You could probably get a whole pair of them for less than sourcing the individual woofer.

Ends Dec 15, 201019:15:17 PST - Right now at $15.00 with $15.61 shipping.

Or maybe you just need to refoam them....

At $26.00 for this kit, I'd opt for whole speakers.

I have a 93 Grand Marquis LS,my radio just stopped emitting sound from all speakers. I have power, the green light shows on the radio face. What can it be something even I can fix I hope.


There may be more than one fuse behind the radio. I have 2, one for the display and one for the output section. It is possible the second of those has blown . To check you will need to access the
wiring behind the radio underneath the dqshboard

Hi,

Initially, pls verify the splicing/wiring:

If verified and still no sound, either:
  • setting configuration (menu); or
  • internal fault of the Pioneer unit.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

blem: I get noise on my car audio system that disappears when I turn the car off.
Possible Cause

Suggested Solution
Alternator or ignition noise is being picked up through the power connection. Install a 12-volt noise filter between the power tap and the power input on your car audio. Back to the Troubleshooting Index Problem: The sound distorts at high volume when I play the radio in my car audio system.
Possible Cause

Suggested Solution
The radio wattage is too low to drive the speakers. Use a car amplifier to increase the radio's power. Replace the speakers with ones which match the radio's output. Back to the Troubleshooting Index Problem: My car radio only get one station.
Possible Cause

Suggested Solution
There is a problem with the wiring. Check the antenna circuit and rewire if necessary. There is a problem with the antenna. Check the antenna and replace if necessary. There is a problem with the radio. If you received more than one station with your previous system and you have already checked the wiring and the antenna, either replace the radio or send it to a service center. Back to the Troubleshooting Index Problem: My car radio keep running hot and blowing fuses.
Possible Cause

Suggested Solution
The wires to different speakers have been combined rather than run separately. Make sure that each of the speakers has 2 wires run to it. Combining speaker wires will cause this problem. Back to the Troubleshooting Index Problem: I lose my station memories in my car radio when I turn off the vehicle.
Possible Cause

Suggested Solution
The tuner memory wire may not be connected properly. Connect the yellow wire to your vehicle battery's positive (+) terminal or to a fuse that provides a continuous source of 12 volts. This connection provides continuous power for the clock and tuner memory when the ignition is turned off. Back to the Troubleshooting Index Problem: The amplifier stays on for a few minutes, then shuts off, then comes back on, then shuts off again.
Possible Cause

Suggested Solution
It is overheating due to power issues. Check your power ratings to be sure they match the amplifier's specifications. There is a problem with the amplifier. If the power ratings are correct, the amplifier needs to be sent to a service center. Back to the Troubleshooting Index Problem: When using two amplifiers, I lose the right channel on one amp.
Possible Cause

Suggested Solution
There is a problem in the sound system or wiring. Try swapping amplifiers or bypassing that amp. If the problem persists on the right channel on both amps, check the wiring and sound system. There is a problem with the amplifier. Replace the amplifier that displays the problem or send it to a service center .

Power but no sound help plz....


well here we go how do you have your pioneer radio connected .
did you run the radio speaker wire out to the factory speaker or did you have an amp connected to the rca output jacks.

1 well if the radio connect by the speaker wire out the
output chip in the radio is fried and needs repair ....

2. if u have a amp connected to power your speakers for sound
check the amp to make sure you have power and no lose connection or speaker wires disconnected.
3. it also possible that the rca jacks are fried too


I no by experience that pioneer loses ground on the audio output jack (rca) well what we did to fix it is..
take and 18 gauge wire stripe back about 1/2" to 1" of the insulation to expose the copper wire and wrap this around the metal casing of the rca jacks and then ground the wire to a ground point do this for both left and right rca jacks...

Motorola S805 headset worked fine with T60 laptop


Solution I found with the same devices is to properly par the devices.

Refer http://direct.motorola.com/ens/s805/QuickstartGuide.pdf

It basically states :

1.Ensure the headphones are turned off (L indicator light not blinking).
2.Press and hold L button. After about 6 seconds, the L indicator light becomes steadily lit.
3.Release the L button. The L indicator light remains steadily lit.

If the L indicator light is flashing or not steadily lit, repeat steps 1 through 3

Now on the T60:

Search for Bluetooth Devices as you would normally.
The T60 lists Bluetooth devices it finds.
Select Motorola S805.
Select OK or Yes to pair your headphones
with your phone.
Enter the passkey: 0000
Select OK.
When your headphones successfully pair
with your phone, the L indicator light
changes from steadily lit to rapidly flashing.

That's it next time you start a audio program on T60 output will be sent to Motorola Headphones

2-way radio causing voltage to spike


Hi and welcome to FixYa,

Your described problem indicates that the RF from the Motorola is being received by the electronic regulator of the alternator and is erroneously factored in as sensor/triggers. Simply stated, the RF causes the regulator transistor to conduct more allowing higher voltage output. There could possibly be two ways of addressing the issue: regulator/alternator side and/or the Motorola side. Things that you could try:
  • shunt a reverse protection diode across the output of the alternator to the ground;
  • install filter condensers on all the wires leading to and from the alternator;
  • wire a ground strap (not a ground wire) from the firetruck's - terminal of the battery to the alternator housing;
  • check/improve (lower down) the SWR of the antenna;
  • if you are using a magnetically mounted antenna, replace with a gutter mount or similar mounting brackets;
  • wire a ground strap (not a ground wire) from the antenna mount to the radio to the body of the firetruck to the alternator to the - terminal of the battery.
A ground strap is a flattened braided electrical wire unlike the common stranded auto electrical wire.

Pls post back results. Good luck and thank you for using FixYa.
