Having trouble with all my speakers except my twitters in a 2007 Saturn Outlook...what do I start with? Fuses are good


Speakers get power from the amp if your system has one or from the radio , if the tweeters work it's not a fuse problem . You like listen to your stereo loud . Blew a channel in the radio or amp ?
Take it and have it checked for DTC'S - diagnostic trouble codes
DTC B1025 01: Audio Output 1 Left Front Circuit Short to Battery
DTC B1025 02: Audio Output 1 Left Front Circuit Short to Ground
DTC B1035 01: Audio Output 2 Right Front Circuit Short to Battery
DTC B1035 02: Audio Output 2 Right Front Circuit Short to Ground
DTC B1045 01: Audio Output 3 Left Rear Circuit Short to Battery
DTC B1045 02: Audio Output 3 Left Rear Circuit Short to Ground
DTC B1055 01: Audio Output 4 Right Rear Circuit Short to Battery
DTC B1055 02: Audio Output 4 Right Rear Circuit Short to Ground

Each of the audio output channel circuits (+) and (-), at the radio and audio amplifier (if equipped) have a DC bias voltage that is one half of the battery voltage. When using a DMM, each of the audio output channel circuits will measure approximately 6.5 V DC. The audio being played on the system is produced by a varying AC voltage that is centered around the DC bias voltage on the same circuit. The AC voltage is what causes the speaker cone to move and produce sound. This voltage will vary depending on what type of audio is being listened to, talk or music, and type of music, as well as the volume setting of the system. Low volume and talk settings will measure around 1V AC and less, where constant music may measure 3 V AC and slightly higher.
Do you know how to do DC voltage testing ?
Without Amplifier without UK6
Ignition OFF, disconnect the harness connector at the appropriate speaker.
Radio ON, test for 5.0-7.5 V between the signal circuit terminal A and ground.
? If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the radio.
? If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the radio.
Test for 5.0-7.5 V between the signal circuit terminal B and ground.
? If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the radio.
? If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the radio.
If all circuits test normal, replace the speaker.

Pioneer vsx-d466s receiver shut down while playing music


Either the power supply went south or one of your amp output stages has been blown.

I have a 2009 GMC Yukon and rear speakers aren't playing


Does the system have an amplifier ?
Circuit/System Verification
Radio ON, Rear Seat Audio (RSA) OFF (if equipped), adjust the fade and balance controls on the radio to test all four channels individually. Each of the four channels should produce clear and even sound.
Without Amplifier Radio ON, verify clear audio is heard from each audio speaker.

If audio is inoperative from all speakers, replace the radio.

If audio is inoperative from one or more, but not all, speakers or the audio emitted from the speakers is not clear, refer to Speaker Circuit Malfunction - without Amplifier.
With Amplifier Radio ON, verify clear audio is heard from each audio speaker.

My Marantz SR6200 is not playing loud and it only plays in analog and when it does and I select tuner cd or Dvd will play, there is also a little crackling on the front right speaker. please if anyone...


Hi, maybe you have speakers misconnected or speakers wiring with short circuit (joined bare cables), please check them because if this continues for a long time, your device could get damaged.

Will not power up


Many receivers are built with relay protection on all speaker outputs. Very handy if there happens to be a questionable speaker or maybe a short circuit in the speaker wiring. What happens is the receiver checks each load on the speaker outputs and if it senses a problems it won't activate the relay to switch audio to the outputs.

Pull you system to pieces, speakerwise, and check if there is a broken or shorted connection. Repair the cable and switch the receiver back on to see if you've solved the problem. If it hasn't then a trip to your friendly repairman may be in order. An interal problem can cause similar clicking noises. But I wouldn't recommend poking around the innards if you are unsure of your abilities.

I unpluged back left speaker, forgot to turn off the power and the wire somehow droped down on the floor and smell burn with sound of shot circuit between + and - , after that my speaker does not make any...


Sorry, once there is short circuit happened in one of the component of a set devices mainly your surround sounds speakers and since they are all interconnected of there will be a chain reaction, one short circuit runs through the other device and then another short circuit will happen.

To make it short, if your speakers still have a warranty contact the manufacturer for support and most probably parts replacements.

If all else fails, purchase a new one...

Please never forget that on all electrical and electronic devices, especially home appliances, NEVER PULL OUT THE PLUG IF ITS TURNED ON, TURN IT OFF FIRST.

Hope these helps.

AR Wirells Speak Transmitter Stopped Working


Hi there ,

Let me know if you did the steps below, then we can proceed form there:

Try unplugging the transmitter from power adapter, if it also has batteries remove them. Also unplug transmitter audio cable.

Then remove batteries/unplug adapters from speakers.

Wait few minutes and reconnect the system.

This is a proper hard reset, and can fix minor problems.

If when you re connect the transmitter does not glow, or you do not have sound on one or both channels then there is a fault.

Check the transmitter audio cable, a short in there can cause troubles.

over load means your speakers and its cable----please check it for bad cable or bad speaker------try to insert speaker one by one and test each time to investigate the bad one.--------if every thing is ok and you keep good ventilation around your receiver (no blocking of ventilation holes)and you still have a problem your protection circuit in your receiver needs to be checked by service technician

Solid state transistor amplifier. The speaker 'thumps' loud when switch on.


check proper connection to output stage(good condition of speakers cables)no short in cables or touching each other.-no problem in speaker itself(speaker coil short circuit or open circuit)-disconnect all from amp and check if it is ok-you will have a problem in cables or speaker if not you will have a problem in your amp.

Avr1100 is on protect


please check speakers cables for internal short circuit-short circuit between cable and cable near it-defective speakers(short circuit in speaker coil)-trouble in receiver output stage(workshop repair).
