I have a 2001 GMC Yukon XL and several months ago, I started having a problem with the OEM radio. The radio evolved to the point where it was in constant state of resetting itself on and off. The clock would reset and the blink off and within seconds come back and then repeat over and over. I checked the instrument panel fuse and pulled the radio from the dash and saw no shorts in the wiring. I ordered an aftermarket radio, wired it in and now I have constant power but have no sound out of any speakers. Confirmed that my splicing was correct for each of the speakers. Still have power but no sound. Any suggestions on how to trouble shoot this problem?

Hi,

Initially, pls verify the splicing/wiring:

If verified and still no sound, either:

• setting configuration (menu); or
• internal fault of the Pioneer unit.

Current transmit to the woofer ll cause tis sort of pro...try to check ur woofer connection and see

Sir,

Try to reset the radio, there is option called Advanced Sound Retriever just click it that.

thanks
good luck

First off it would be a good idea to check your speakers work. Remove them to see if they are in fact connected, DISconnect them one by one and do a battery check with each speaker. Simply use a 9v alkline battery and place the battery on to the speaker terminals(DO NOT connect the battery to the wires comming from the car or radio) do this test to expect a click or popping sound from the speaker being tested. Once you have checked that each speaker response to the battery it is now time to use one speaker as your testing tool to find or check for output sound off of your radio. Take just one of your working speakers and extend wires from the spkr terminals long enough for the speaker to be places on your seat or a safe and stable service. Remove the radio and locate the speaker wire output or wiring diagram if available. Most after market radios like Alpine,Sony and Pioneer will have a standard wireing system..as follows, (+Gray,-gray/back=front right)(+white,-white/black=front left)(+green,-green/black=left rear)(+purple,-purple/black=rear right) NOTE(Do not connect the 2 wires together but 1 wire from the speaker lead, to only 1 wire from the speaker out on the radio and the other speaker lead wire with the other speaker out from the radio) Connect the leads from the speaker to the speaker wires that lead dirrectly out of the radio to check for sound. If you have a nissan radio in yout car you will need to refer to the wiring diagram to locate the speaker output wires. Be sure not to confuse the power wires with the speaker wires or you run the risk of popping your test speaker.It would be a good Idea to use an old junk speaker while doing this test.(After market power wires are commonly solid yellow+ ,solid red+ or somtimes solid orange+)The factory Nissan speaker wires that you find at the speaker should match the same colors behind the OEM radio to narrow down your options. If your system has a factory or after market amp you will need to do a more advance check.

Try unplugging radio connectors for a while.
If you are sure there is no short in connectors inspect radio buttons, a stuck button can cause same problem.
Check memory connector at the back, one of the wires connect power to memory on many car stereos.

Please mention Model and Brand of your car radio to understand the problem.
