If it turns off when going round a corner or on a bump, this would mean that a connector is loose at the back of the unit. The amp in the vehicle needs a turn-on signal and it gets it on that last wire in the black plug. Can anyone point me in the right direction as to what the problem may be please. Have you double checked that the traffic announcement service is turned off? I replaced my battery the other day and after I did the radio is no longer putting out sound. If this is the problem, you may be able to find a used head unit at a wrecking yard for not too much. But If you decide to get an aftermarket stereo, I'd run new speaker wires from the radio to each speaker, bypassing the factory amp.
I'm not 100% sure if all trucks had factory amps or not, but I know mine does. If there is no sound coming through the speakers on all inputs, you may have a problem. The first thing you should do before checking wires is to test different audio inputs. On an 88 the amp is located behind the radio mounted in a 'U' shaped bracket. Without the radio removal key sets, you will have a hard time removing your radio. I don't think I have an amp. What would be going wrong for that to happen? I have read this in a few other threads, wondering if anyone else can confirm this? Not the most common radio issue due to technological advances.
Hi Sue, Sorry to hear about your problems. Some buttons are somewhat open to the air and dust can get in there. Open that speaker and check the connections. Both radios come on, and can change screens, and the back up camera works too. But does not show up with volume up. Hi jonny have you ever heard sound come from the speakers was it working then stopped? I did install my after market speakers, no subwoofer, just in the doors and front dash. There is nothing more irritating whilst driving your car than car audio problems.
This is like the head unit is on but with the volume down,, bit like white noise. You are then able to use the positive and negative wires of the speaker against the positive and negative of a car battery. I got the same problem. If they do play, reconnect them to the system and continue. It is a silver box that looks more like an ecm computer or somthing than an amp.
Daggar, I will check the speaker wires to look for shorts. If the wiring is all connected correctly, check the ground connector that attaches to your vehicle. I think there's an amp looking under driver seat. The radio screen works fine and it shows that it's playing. Remember to always turn off the power to the system and components before connecting or disconnecting cables and wires. Listen very close and if this is the problem you will hear a faint static noise from the problem speaker.
Why Are My Car Speakers Not Working? Start with disconnecting as many interfaces on the back of the head unit as possible, and add from there. Just seems strange that both front door speakers should go at the same time. I'm another one in this boat so. Quite often it can be the simplest, silliest reason you might get a chuckle out of it later on as to why the system stopped working or wasn't working from the get-go. When I first installed it, I took the easy route and wired all the speaker wire to the wires in the dash that go to the amp and then wired up the amp turn on wire to the radio remote wire.
Always try to avoid having a free or very cheap audio install. There aren't any fuses for the speakers or anything like that and, like I said before, the factory radio produces sound. Confirm that the and are inserted far enough to make good, steady contact with the speaker terminals. The use of a multimeter can also prove useful when testing for problems such as polarity. Its also a possibility that the factory amp crapped out on you. If your car radio is not working then the speakers will of course not work too. This vehicle is the most frustrating I have ever dealt with.
If the speakers still won't play, they may be damaged or defective. Leave the volume down low, lest you blast your ears once the audio is playing fine again. I had purchased another bypass harness but it was the wrong one. I have check and double checked the wiring harness and it is connected correctly. There is no point ripping the wiring harness until you are sure the speaker wire is at fault. So I bought an identical used replacement radio on ebay, still not working and the same problem.
