I GET NO OUTPUT TO SPEAKERS

If your 2008 GMC Sierra has power and everything works but you don't have sound from the Power Acoustik WMH7-S1 after wiring it in, here are some steps you can follow to try and troubleshoot the issue:

1. Check the wiring: Make sure all the wires are properly connected and tightened. Confirm that the ground wire is securely connected to the vehicle's chassis.
2. Check the fuses: Make sure the fuses for the audio system are not blown. Check both the main audio fuse and the subwoofer fuse if applicable.
3. Check the speaker wiring: Confirm that the speaker wiring is correct, with the correct polarity (positive to positive, negative to negative).
4. Test the head unit: If you have a multimeter, you can use it to test the head unit's output voltage. The voltage should be between 11 and 14 volts DC. If the voltage is too low, the head unit may not be providing enough power to the speakers.
5. Check the speakers: If you have a multimeter, you can use it to test the speakers. Confirm that they have continuity, and that the speaker wiring is not damaged or shorted.

If you've tried these steps and are still experiencing issues, you may want to consider consulting a professional to help diagnose and resolve the problem.

It sounds like the Yamaha RX V1000 is not properly outputting sound from the speakers. Here are a few things you can try to troubleshoot the issue:

1. Check the volume: Make sure the volume is turned up on the receiver and on the connected source (such as a TV or Blu-ray player).
2. Check the speaker connections: Make sure the speaker wires are securely connected to the receiver and to the speakers. Double check that the speakers are connected to the correct terminals (positive to positive, negative to negative).
3. Check the input/output settings: Make sure the receiver is set to the correct input and that the connected source is set to output sound. Also, check the Yamaha RX V1000's settings to ensure that the speakers are set to "on" and that the correct speakers are selected.
4. Check the mute function: Make sure the mute function on the Yamaha RX V1000 is not activated.
5. Check the amplifier section: Sometimes, the issue could be with the amplifier section of the receiver, which can be tested by a professional technician.
6. Check the firmware: Make sure the firmware of the Yamaha RX V1000 is up to date, if not update it.

If none of these troubleshooting steps resolve the issue, it may be best to contact a qualified service technician to inspect and diagnose the problem. They may be able to troubleshoot the problem and make necessary repairs, or advise on replacement of certain parts if necessary.

I'd have to see the circuitry to be certain, but it's a good possibility that an output driver transistor shorted and blew the speaker amplifier power supply fuse. (I'm assuming the amplifier power supply is fused separately from the power to the rest of the docking station.)

The troubleshooting procedure (the docking station MUST be unplugged!) is to remove the cover and look for a fuse that is likely to be for speaker power (there is almost certainly one for the AC power coming in; it will be close to the power cord attach point; this is not the one we're looking for unless everything in the i30 is dead. Once you identify the fuse(s), check them for continuity with an ohmmeter. If you find an open (blown) fuse, trace circuit to the speaker amplifier. Use an ohmmeter to measure the resistance from the speaker output to fuse, and from the same terminal to the opposite polarity power supply (Most audio output amplifiers use both positive and negative power supply voltages.) A shorted output transistor will read very low resistance from the speaker to one of the supplies. If one of the transistors is bad, both must be replaced because the other one was abused (enough current to blow the fuse went through it.) In many newer audio systems, the output transistors are inside a power amplifier module, so replacing the module automatically replaces both transistors.

Look very carefully when you assemble the boards as your audio output line is being shorted out when it is assembled.there must be a thin wire that is not returned to its proper position and then gets pinched,Quite a common fault when re assembling such delicate items.

With this particular unit you have a Tele mute which is cell phone related to mute volume when your cell phone rings if this is grounded then you have a problem.

1) Verify that the speakers of the vehicle are correctly hooked up , you can test your speakers by taking a 9 volt battery and touching the positive and negative leads of the speaker wires (make sure they are disconnected for radio) you should hear a click.

2) Take a volt/ohm meter set it to ohms touch the leads together this is continuity. Next touch the wire leading to the speaker to be tested and place the other lead of the meter to the bare metal of truck. If the needle pegs all the way over you have a shorted wire.

3) If using a seperate amp to power the speakers you need to insure that all connection to the amp are made properly and grounds are correct.

One other thing to check is the center channel balance as if it is biased you need to adjust it.

There are only a few simple things that can cause no audio output
1) Volume not correct
2) Audio output connections incorrect
3) Speaker wires are bad
4) damaged speakers
5) tele mute is grounded
6)Speaker wires insulation is cut and grounding out or is not making a good connection
7) worst case Radio is defective ( it happens)

make sure the unit is switched off and the clock is displayed then

Hello deeprajm,

Shorted or low impedance outputs can cause the "CUR" display. Power down everything and remove the speaker wires. If it will then power up without the display, the problem is probably a short in the speaker wire or voice coil, or the impedance load is too low. If there are multiple subs, reconnect them one at a time to isolate the bad one and then correct the problem. If the amp works properly with either of the subs but not both, rewire the subs for a higher final impedance.

If the amp still displays "CUR" with the speakers disconnected, there's most likely an internal fault that requires component level repair.

Hope this helps.

It probably has shorted output transistors. To eliminate other possible causes, read through the following page.

Amplifier in Protect Mode - Troubleshooting

Let me know if you have any other questions.

Not unless you know how to troubleshoot solid state electronics. If you disconnected the speakers and the unit still goes into the protect mode, most likely you have a short in one of the power output stages. Good Luck
